Paving Breakers & Jackhammers
Four weight classes, standard or Airgo-Line® anti-vibration, every variation in stock. New to breakers? Start with our Paving Breaker Buyer’s Guide.
APT Paving Breakers & Jackhammers
The classic air jackhammer ladder: 33-lb M117 for slab and confined work, 43-lb M140 for plant maintenance, 68-lb M160 for general breaking and asphalt, and the 90-lb M190 for heavy demolition and road building. Airgo-Line® anti-vibration back heads available on the 140, 160, and 190.
Choose it when: you break concrete, asphalt, or frozen ground off compressor air — pick the weight class for the slab and the chuck for your steel.
Key specs
M160 · 60-lb Class
APT 160 Pneumatic Paving Breaker
The general-purpose jobsite breaker and our best-selling APT jackhammer class: 68 lb of slab, roadway, and asphalt-cutting muscle at 1,680 BPM, in your choice of 1-1/8 x 6 or 1-1/4 x 6 in. chuck — standard back head or the Airgo-Line® anti-vibration version.
Choose it when: one breaker has to cover most of your concrete and asphalt work — the 60-lb class is the do-most answer.
Key specs
Rock Drills — Anchor Holes to Blast Holes
Four hand-held air drills from 9 to 61 lb, wet and dry versions, all taking standard hex-shank steel we stock. Sizing help: the Rock Drill Buyer’s Guide.
Light & Midsize Rock Drills
The 9-lb M109 and 19-lb M115 drill anchor-bolt and dowel holes with a stop-rotation mode for percussion-only chipping; the 38-lb M137 is the midsize production drill with four speeds and wet/dry options for utility work and dowel drilling machines.
Choose it when: holes are smaller or fewer — anchor bolts, dowels, handrail posts — and an easy-carry drill beats a 60-lb sinker.
Key specs
M155 · 60-lb Class
APT 155 Pneumatic Rock Drill
Our best-selling APT tool. A 61-lb sinker drill with three drilling speeds, wet or dry flushing, and a drilled-hole blow-out function — it powers through granite, hard-faced rock, and quarry material and drills secondary blasting holes all shift.
Choose it when: you drill production holes in rock — quarries, foundations, secondary blasting — and penetration rate pays the bills.
Key specs
Rivet Busters — Breaker Power, Held Sideways
One of the strongest rivet buster lines still in production — and one of our biggest APT sellers. How to choose: the Rivet Buster Buyer’s Guide.
APT CN Rivet Busters
A stroke ladder for horizontal demolition: the compact 6-in.-stroke M633CN for tight spaces, the 8-in. M133CN that meets bridge-deck weight rules while hitting like a 60-lb breaker, and the 11-in.-stroke M1133CN Jumbo for reinforced concrete and tank cutting. D, pistol-grip, or T handles; all run jumbo 11X extra-heavy-duty steel.
Choose it when: you cut rivets, break bridge deck or walls horizontally, or need breaker-class energy at half the weight.
Key specs
M133CN · 8-in. Stroke
APT 133 Pneumatic Rivet Buster
The sweet spot of the CN line: an 8-in. stroke that delivers impressive impact energy at just half the weight of a 60-lb breaker, and it meets bridge-deck repair weight requirements. Drop-forged D, pistol-grip, or T handle; runs jumbo 11X extra-heavy-duty steel.
Choose it when: bridge deck, walls, and horizontal demolition are the daily work — the power-to-weight pick of the lineup.
Key specs
Backfill Tampers
Our highest-volume APT tool — 126 sold in the last two years. Compaction basics: the Tampers & Rammers Buyer’s Guide.
APT 131 Pneumatic Backfill Tamper
The workhorse trench tamper: 670 slow, hard blows per minute pack clay and backfill solid for foundation repair, pavement patching, asphalt packing, and setting power or telephone poles. A flapper valve lets dirt pass without stalling the tool. Choose the 6-in. iron butt, 3-in. solid butt, or pole (half-moon) butt.
Choose it when: trench backfill, pole setting, or patch compaction is the job — this is the tool utilities and contractors reorder most.
Key specs
Chipping Hammers
The classic pistol-grip air hammers, all priced the same — pick by stroke and nose. Full walkthrough: the Chipping Hammer Buyer’s Guide.
APT Chipping Hammers
Seven models for scaling, chiseling, form stripping, cement finishing, and light demolition — from the 12-lb, 2-in.-stroke M652 to the 4-in.-stroke M44 with a drop-forged four-bolt handle. Every model comes in .680 round or .580 hex nose, with your choice of retainer and optional whip hose and oiler setups.
Choose it when: you prep surfaces, chip concrete build-up, or strip forms — match stroke length to how hard you need to hit.
Key specs
M263 · 3-in. Stroke
APT 263 Pneumatic Chipping Hammer
The 260-series workhorse: a 14-lb, 3-in.-stroke chipping hammer with APT’s patented automatic ball valve and a drop-forged handle, hitting 1,650 BPM on 33–35 CFM. Scaling, chiseling, form stripping, and mixer clean-out in a package light enough for overhead work.
Choose it when: you chip all day — the 3-in. stroke balances hitting power with control, in .680 round or .580 hex nose.
Key specs
Clay & Trench Diggers
APT Clay & Trench Diggers
Digging tools for ground a shovel will not touch: the 31-lb D-handle M118 breaks clay, shale, hardpan, and frozen ground; the 21-lb M125 is the light, maneuverable digger for tunneling around foundations; the 37-lb T-handle M119 trench digger cuts trenches for pipe and line work.
Choose it when: you dig in hard clay, frozen ground, or under existing structures — with spade and tamper steels to match.
Key specs

Chipping hammersAPT Questions, Answered
Where can I buy American Pneumatic Tools (APT)?
Right here — Crowder Supply is a stocking APT dealer based in Denver, Colorado, shipping nationwide. The paving breakers, rock drills, rivet busters, chipping hammers, tampers, and diggers on this page are in our warehouse with genuine APT parts and matching steel, and our product experts size tools to jobs by phone at 1-888-883-5144.
Are APT tools made in the USA?
APT — American Pneumatic Tools — is a California-based brand whose name has stood for pneumatic tool quality since 1938. Per APT, products and parts are made in various countries by its affiliates and trusted suppliers. What matters on the jobsite: the designs are the proven classics, genuine parts are readily available, and we stock both tools and parts in Denver.
Is this the same APT as APT cutting tools or inserts?
No — we stock American Pneumatic Tools, the air-tool maker. Carbide inserts, reamers, and machining cutters sold under similar names are different companies. If it runs on compressed air and breaks, drills, chips, or tamps, this is the right APT.
What do the old APT part numbers like 5235, 5240, or 18768 mean?
APT renumbered its catalog, but the old numbers still identify the same tools: 5199/5200 = M117, 17923 = M140, 5235/5236 = M160, 5239/5240 = M190, 5229–5234 = M155 rock drill options, 5214 = M131 tamper, 18757/18768/19444 = M133CN rivet buster handles. Order by either number — and our product pages list both.
What sizes of APT jackhammer are there?
Four classes: the 33-lb M117, 43-lb M140, 68-lb M160, and 90-lb M190 — each in your choice of chuck, with Airgo-Line® anti-vibration back heads available on the 140, 160, and 190. See the full paving breaker page for specs and prices.
What size air compressor do APT tools need?
At 90 psi: the M109 drill runs on 19–21 CFM, chipping hammers about 32–35, the M117 breaker 34–38, the M131 tamper 38–42, rivet busters 42–52, the M160 60–65, the M190 75–80, and the M155 rock drill 110–120. Size the compressor with headroom for hose length and altitude — we stock towable compressors to match.
What is the Airgo-Line?
Airgo-Line® is APT’s anti-vibration series: an ergonomic back head (interchangeable with the standard one) that cuts vibration to the operator’s hands and arms with no loss of breaking power. Available on the M140A, M160A, and M190A breakers and the M633CN rivet buster design.
Do you stock APT parts?
Yes — genuine APT chisel retainers, rubber bumpers, whip hose assemblies, repair kits, pistons, rifle bars, and handle parts are on our shelves. Call 1-888-883-5144 with the model and part number and parts ship same day.
Which APT rock drill should I get?
For anchor bolts and dowel holes, the 9-lb M109 or 19-lb M115 — both switch to percussion-only mode for light chipping. For production drilling, the 38-lb M137 or the 61-lb M155, each in wet or dry versions; the M155 adds a drilled-hole blow-out function and is our best-selling APT tool. All chucks take standard hex drill steel we stock.
How fast do APT tools ship?
In-stock tools ship same day on orders placed by 4 PM Eastern. Most items go free by UPS Ground, and everything ships from our Denver, Colorado warehouse.
