Chicago Pneumatic Construction Tools
Pneumatic, gas and hydraulic breakers, rock drills, chipping and air hammers, rivet busters and tampers — plus CP portable air compressors, generators, light towers and desiccant dryers. Real stock, real prices, and people who run this equipment.
This page is Chicago Pneumatic Construction Tools. CP impact wrenches, ratchets, die grinders, sanders, drills, screwdrivers and workshop equipment are a separate division — and we stock all of it. CP7000 series air hammers and the RA and B20 scalers live here, with the chipping hammers.
The short version
Breaking concrete with air on site? Start at the CP pneumatic paving breakers (30 to 90 lb class). No compressor on site? The gas-powered Red Hawk runs standalone. Working off a carrier or power pack? See the CP BRK hydraulic breakers. Drilling rock? The CP sinker drills run 9 to 60 lb class. Chipping, scaling or gasket work? Seventeen chipping and air hammers from $86, in .580 hex and .680 round for construction and 0.401 in. for shop work. Need the air to run them? CP portable compressors deliver 95 to 1,600 CFM. Need power, light or dry air on the same site? CP also builds portable generators, LED light towers and desiccant air dryers. Want every brand side by side instead of CP alone? Use the all-brands categories: paving breakers, rock drills, air compressors. Not sure? Call 1-888-883-5144 and describe the job.
CP Pneumatic Tools
Air-driven breakers, drills, hammers and tampers — the core of the Chicago Pneumatic construction line since 1901. Every tool below runs on a standard portable compressor; the CFM figure on each model tells you how big that compressor has to be.
Paving Breakers & Jackhammers
30 to 90 lb class, 45 to 81 CFM. New to sizing? Read the paving breaker buyer’s guide.
CP 1260 Pneumatic Paving Breaker
The 60 lb breaker that does most of the work on most crews: enough mass to move 8 in. slab and footings, still light enough that one operator can reposition it all day. Built in vibration-reduced and mufflered configurations.
Choose it when: You are breaking 6 to 12 in. reinforced slab, sidewalk, curb and light foundation and you want one breaker that covers nearly all of it.
Key specs
Pneumatic Rock Drills (Sinkers)
Hand-held sinker drills for blast holes, anchor holes, dowel bar and rebar pinning — 9 to 60 lb class. See the rock drill buyer’s guide and the drill steel & adapters guide.
CP 0069 Pneumatic Rock Drill
The big sinker: 60 lb class, 130 CFM, built for production blast-hole work in hard rock where a lighter drill stalls. Available in 7/8 x 4-1/4 in. and 1 x 4-1/4 in. shank.
Choose it when: You are drilling deep blast holes or hard formation and penetration rate matters more than tool weight.
Key specs
Rivet Busters
Also called rivet guns and rivet hammers — for shearing rivets on bridges, tanks and structural steel, and for concrete work where a breaker will not fit. See the rivet buster buyer’s guide.
CP 4611 Pneumatic Rivet Buster
The 11 in. cylinder stroke delivers the heaviest single blow of the three CP rivet busters, at 720 BPM. Sold in pistol grip and D-handle; the D-handle is the crew favorite for overhead and bridge work.
Choose it when: You are cutting heavy structural rivets or need maximum energy per blow rather than fast cycling.
Key specs
Chipping Hammers & Air Hammers
Seventeen models from $86 to $1,076, in two families that are not interchangeable. Construction chipping hammers take .580 hex and .680 round steel, weigh 7 to 20 lb and run 20 to 33 CFM — concrete prep, scaling, gasket and weld work, light demolition. Light-duty air hammers take 0.401 in., 0.498 in., 3/8 in. and 1/2 in. hex shanks, weigh 2.4 to 4.9 lb and run 6.4 to 25 CFM — vehicle service, fabrication, foundry and precision scaling. Buy the shank your steel already fits. See the chipping hammer buyer’s guide.
CP 4123 Pneumatic Chipping Hammer
Six configurations across 2, 3 and 4 in. strokes in both .580 hex and .680 round shank, with the standard oval collar retainer and spring. More of these leave our dock than any other Chicago Pneumatic tool.
Choose it when: You need a general-purpose air chisel for weld cleanup, scaling, gasket removal and concrete finishing, and you want the shank that matches the steel you already own.
Key specs
Backfill Tampers
Air tampers for trench backfill, pole holes, pipe bedding and around foundations — where a plate compactor will not fit. See the tampers & rammers buyer’s guide.
CP 0004 Pneumatic Backfill Tamper
The largest butt in the CP tamper line at 6-1/4 in., running 780 BPM on 28 CFM. Covers ground faster per pass than the 5 in. tool while still fitting a standard utility trench.
Choose it when: You are compacting utility trench backfill in lifts and want the widest butt that still fits between the trench walls.
Key specs
Clay & Trench Diggers
Long-barrel diggers with a clay spade for hardpan, frozen ground and hand-dug trench — lighter and faster than a paving breaker in soil.
Scabblers, Chisels & Needle Scalers
Surface preparation, split by substrate. Scabblers scarify concrete — laitance, coatings and high spots — with carbide pistons hitting straight down at 3,000 BPM on 27.5 CFM. Needle scalers strip rust, mill scale, slag and failed coating off steel without cutting into the parent metal, because the needles ride the contour instead of digging a line.
CP Gas-Powered Tools: the Red Hawk Platform
One gasoline-powered platform, three different machines, all on one page: the CP Red Hawk gas line. Red Hawk tools run with no compressor, no hoses and no power pack — which is the whole point on remote right-of-way, rail, and utility work where dragging air is not practical. Pick by what the tool actually does, not by size.
The Breaker: Red Hawk Road
CP Red Hawk Road Gas Paving Breaker
A self-contained gas breaker that does the work of a 60 lb air breaker without the compressor, hose or fuel to run one. Three shank sizes so it takes the steel your crew already stocks.
Choose it when: You are breaking concrete or asphalt away from the truck, on rail, or on scattered patch work where towing a compressor to each spot costs more than the tool.
Key specs
The Drill: Red Hawk Drill
CP Red Hawk Drill Gas Rock Drill / Paving Breaker
The dual-purpose machine in the platform: rotation for drilling anchor and blast holes, and straight percussion for breaking. One tool, 7/8 x 4-1/4 in. shank, no air supply required.
Choose it when: You need to drill holes in rock somewhere a compressor cannot reach, and you would rather not carry a second tool to break with.
Key specs
The Tie Tamper: Red Hawk Rail
CP Red Hawk Rail Gas Rail Tamper
The rail-maintenance member of the family: consolidates ballast under ties to hold surface and line. Same gas platform, three shank sizes, no air on the right of way.
Choose it when: You are doing track surfacing, spot tamping or turnout work and there is no compressor within a mile of the job.
Key specs

CP Hydraulic Tools
Tools that run off a skid steer, excavator, tractor or a CP power pack. Hydraulic gives you breaker-class energy with far less noise and no air hose — and it is the only practical way to run a post driver or post puller off a machine you already own.
Hydraulic Paving Breakers (BRK Series)
Hand-held hydraulic breakers, BRK 40 through BRK 95. These are operator-held tools, not excavator attachments — for carrier-mounted hammers see the all-brands hydraulic breaker category.
CP BRK 40 Hydraulic Paving Breaker
The entry point into hand-held hydraulic breaking, in all three common shank sizes. Pairs with a CP PAC power pack or any circuit already on the machine.
Choose it when: You want breaker performance without a compressor, and you need a tool light enough to run all shift.
Key specs
Hydraulic Power Packs (PAC Series)
Gas-driven hydraulic power units that make every CP hydraulic tool portable. Also in the all-brands power pack category.
CP PAC P13 Power Pack
The larger of the two CP packs: 5 to 8 GPM at 2,200 psi from a gas engine, enough to drive the bigger BRK breakers, the RDR rock drill and the PDR post drivers.
Choose it when: You are running hydraulic tools with no carrier available, or you want a dedicated power source that is not tied up when the machine leaves.
Key specs
Hydraulic Post Drivers (PDR / MDR)
Hand-held post drivers for T-post, sign post, guardrail and fence work. New to post driving? The post driver buyer’s guide covers sizing across brands.
CP PDR 95R Post Driver
The heavy hand-held driver, in trigger-lever and remote-valve activation. Remote valve keeps the control at the operator’s hand when the tool is up on a post.
Choose it when: You are setting guardrail, sign or heavier fence post and the 30T and 75RV are running out of energy per blow.
Key specs
Hydraulic Rock Drills
One true hydraulic drill in the CP line. If you want a hand-held drill on air instead, the CP sinker drills above are the deeper range.
Pick Hammers & Spike Drivers
Lighter than a breaker, heavier than a chipping hammer — for asphalt, frost, and rail spike work.
Post Pullers
The other half of a fence or guardrail job: getting the old post out without a backhoe and without bending it.
CP Site Power: Air, Electricity, Light and Dry Air
Chicago Pneumatic does not just make the tools — it makes the machines that feed them. The compressors, generators and light towers here now sell online with published pricing; the desiccant dryers are quoted. Call 1-888-883-5144 for freight questions or multi-unit deals and we will price it the same day.
Portable Air Compressors (CPS Series)
Fourteen models with live product pages — diesel towables, utility mounts and portable electrics, 95 to 1,600 CFM of actual free air — every one priced and buyable below. Full spec sections are on the CP air compressors page; sizing across brands is in the air compressor buyer’s guide, and the all-brands air compressor category compares CP against everything else we stock.
CP CPS 185 Air Compressor
The volume machine of the CP range. Turbocharged four-cylinder Kohler KDI 1903 TCR Tier 4 Final, up to 12 percent better on fuel than others in its class, with a spin-on separator that services in under an hour.
Choose it when: You are running two 60 lb breakers at once or a big sinker drill and cannot afford to run out of air mid-shift.
Key specs
Show all 14 CPS models ↓
Also in the CP factory range and quoted by phone: the high-pressure drilling trio (CPS 750-360, 1150-360, 1400-500) and the Cummins-powered CPS 750-200 and 900-150 CUD — call 1-888-883-5144.
Portable Gas Generators (CPPG Series)
Seven 60 Hz models across two lines — quiet inverter units for sensitive electronics and AVR standard units for straight jobsite duty, 1.6 to 6.5 kVA nominal — all CARB and EPA3 compliant, all priced and buyable online. Full spec tables are on the CP generators page.
CPPG5.5W Portable Gas Generator
The middle of the standard line and the one most crews buy: 5 kVA of AVR-regulated 240/120 V power with electric start, built for lights, heaters, pumps and hand tools. The standard line runs 8 to 11 hours per tank — the longest runtimes in the CPPG range.
Choose it when: you want maximum runtime per gallon for general jobsite power and the loads are not voltage-sensitive.
Key specs
Multi-unit pricing is available on the CPPG line — call 1-888-883-5144 with the model and quantity.
Portable Light Towers (CPLT Series)
Three towers — diesel, solar and plug-in electric — all priced and buyable online, with full spec sections on the CP light towers page.
Portable Desiccant Air Dryers (CPD Series)
Twin-tower desiccant dryers that pull moisture out of compressed air down to a -40 degrees F pressure dew point — for sandblasting, instrument air, pipeline work and anything where wet air causes corrosion or product defects. Not yet listed for online checkout; call for pricing and lead time.
CPD 850, CPD 1200, CPD 1700
Fully pneumatic controls, so there is no external power to run — connect air and go. Each machine carries a water separator, an oil-coalescing filter and an outlet dust filter, so the desiccant never sees liquid water and the tool never sees desiccant fines. Up to 20 percent extra activated alumina and wide vessels for low air speed and long contact time. Stackable crash frame with lifting lugs and forklift slots on all four sides.

CP site powerChicago Pneumatic FAQ
Is Chicago Pneumatic the same company as Atlas Copco?
They are related but separate brands. Chicago Pneumatic was founded in 1901 and has been part of the Atlas Copco group since 1987; both brands are sold and serviced independently, with their own model lines, part numbers and dealers. We are a stocking dealer for both, so if a CP tool is on backorder we can usually cross you to the equivalent Atlas Copco machine and tell you honestly which one is the better buy that week.
Do you sell CP shop and vehicle-service air tools like the CP7769 impact wrench?
Yes, and we stock the full line. Chicago Pneumatic makes two very different families of tools, and we carry both. This page is CP Construction Tools: breakers, rock drills, chipping and air hammers, rivet busters, tampers, compressors and site power. The CP industrial and workshop division — impact wrenches, air ratchets, die grinders, angle grinders, sanders and polishers, drills, screwdrivers, riveting tools, air motors, cutting tools and shop equipment — has its own home at CP Industrial & Workshop Tools, with 179 tools and over 1,200 accessories and service parts. One exception worth knowing: the CP7000 series air hammers and the RA1, RA2, CP0456 and B20 scalers are catalogued industrial by the factory, but they do the same job as a chipping hammer, so we list them here alongside the construction hammers rather than making you cross two pages to compare them.
What is the difference between a construction chipping hammer and a light-duty air hammer?
Shank, weight and what the tool is trying to do. A construction chipping hammer takes .580 hex or .680 round steel, weighs 7 to 20 lb and draws 20 to 33 CFM: it is sized for concrete prep, heavy scaling, gasket and weld work and light demolition, and the steel is thick enough to take that abuse. A light-duty air hammer takes a 0.401 in., 0.498 in., 3/8 in. or 1/2 in. hex shank, weighs 2.4 to 4.9 lb and draws 6.4 to 25 CFM: it is for vehicle service, fabrication, foundry cleanup and precision scaling on castings and thin material, where a 13 lb hammer would deform the work. The shanks do not interchange, so the practical rule is to buy the family that matches the steel you already own. The one tool that blurs the line is the CP9362 — 7.4 lb, but on full .580 hex or .680 round steel.
Are you an authorized Chicago Pneumatic dealer?
Yes. Crowder Supply is a stocking Chicago Pneumatic construction tool dealer shipping nationwide. Stocking matters more than the title: most of the tools on this page ship the same day, not in six weeks from a factory order.
What size air compressor do I need to run a CP breaker?
Add up the CFM of every tool you plan to run at the same time, then add about 25 percent for hose losses and duty cycle. Size against the compressor’s ACTUAL free air delivery, not its model number: a CPS 110 delivers 95 CFM and a CPS 185 delivers 180 CFM. So a CP 1260 at 63 CFM runs comfortably on the CPS 110; two of them, or a CP 1290 at 81 CFM alongside a chipping hammer, want the CPS 175 or the CPS 185. Our CP portable compressors run 95 to 400 CFM actual across 15 models, up to 1,373 CFM on the high-pressure drilling machines. Full specs and a tool-by-tool sizing table are on the CP air compressors page.
What is the difference between a CP paving breaker and a clay digger?
A paving breaker is built to fracture concrete and asphalt: heavier, slower-cycling, more energy per blow. A clay digger has a longer barrel and runs a clay spade to shear and lift soil, hardpan and frozen ground. Using a breaker in dirt wastes energy and buries the tool; using a clay digger on concrete will not break it. If the material is a mix, most crews buy the breaker and add a spade shank for the dirt work.
Do you carry CP generators, light towers and air dryers?
Yes. The CPPG generators and the CPLT V17 light tower now sell online with published prices, and the CPD 850, 1200 and 1700 desiccant dryers are available on a quote basis — call 1-888-883-5144 for dryer pricing. Multi-unit pricing is available on the generator line.
Which CP rock drill should I buy?
Match the drill to the hole and the air you have. The CP 0009 at 9 lb class and 20 CFM is for shallow anchor holes and light rebar pinning off a small compressor. The CP 0014 (15 lb, 38 CFM) and CP 0022 (30 lb, 56 CFM) cover most utility and foundation work. The CP 0032 (45 lb, 103 CFM) and CP 0069 (60 lb, 130 CFM) are production blast-hole tools and need a CPS 185 or larger to keep up.
What shank or chuck size do I need?
The shank has to match the steel you already own, not the other way around. CP breakers ship in 1 x 4-1/4 in., 1-1/8 x 6 in. and 1-1/4 x 6 in.; sinker drills in 7/8 x 3-1/4 in., 3/4 x 4-1/4 in., 7/8 x 4-1/4 in. and 1 x 4-1/4 in.; construction chipping hammers in .580 hex and .680 round; light-duty air hammers in 0.401 in., 0.498 in., 3/8 in. and 1/2 in. hex. Measure a chisel you have or send us a photo and we will identify it. One thing to know before you order steel: for .580 hex and .680 round we sell our own points and chisels rather than the factory part numbers, in lengths from 8 to 120 in.; for the light-duty air hammers we sell the manufacturer’s SKUs.
Do you stock parts and repair kits for CP tools?
Yes. Wear parts, seal kits, retainers, springs and pistons for the CP construction line are part of our regular stock, and parts orders ship the same day on the same cutoff as machines. Call 1-888-883-5144 with the model and, if you have it, the part number off the old piece.
Gas, pneumatic or hydraulic: which platform should I standardize on?
Pneumatic if you already own or rent a compressor: lowest tool cost, simplest service, widest range. Gas if the work is scattered and remote and towing air to every spot costs more than the tool. Hydraulic if you have a carrier or a power pack, want much lower noise, or need post drivers and post pullers, which have no practical pneumatic equivalent. Most crews end up with pneumatic as the base and one gas or hydraulic tool for the exceptions.
How fast do CP tools ship?
Same Day Shipping on orders by 4 PM Eastern on stocked items. We ship nationwide from our own stock and, on some lines, direct from the manufacturer, so transit times depend on the item rather than on one warehouse. Larger machines such as compressors, generators and light towers ship by freight, and we quote the freight with the machine so there is no surprise at delivery.
