Jack Hammer Bits: Paving Breaker & Clay Digger Points and Chisels
Break and trench concrete and pavement with the working points that take the impact. Moil points concentrate force to start a break, narrow and 3-inch chisels cut and trench, and tie tamping tools pack ballast, all for the breakers in our paving breakers & jackhammers range. Every point and chisel comes in all five breaker shanks — 7/8 x 3-1/4, 7/8 x 4-1/4, 1 x 4-1/4, 1-1/8 x 6, and 1-1/4 x 6 in. — in lengths from 14 to 168 in. For the full steel catalog, see tool steel.

Jack Hammer Bit Types
A moil point punches and starts holes — it concentrates the breaker’s blow into a single point to open a crack in slab or rock. A narrow chisel steers the break line and trenches. A 3 in. chisel clears and shaves once the slab is opened. A tie tamping tool packs ballast under railroad ties. For cutting and digging blades — asphalt cutters, asphalt wedges, clay spades, frost wedges, concrete busters, and brick removing tools — see blade tools. To set posts, pipe, and ground rods with a breaker, see driving tools. For 0.580 hex steel that fits smaller air tools, see chipping hammer chisels.
Jack Hammer Bit Sizes
Bits are not universal — the shank must match your breaker’s chuck. The shank size is stamped on the tool and listed on every breaker product page. All five sizes below are stocked for every point and chisel on this page.
| Shank size | Breaker class | Example breakers |
|---|---|---|
| 7/8 in. x 3-1/4 in. | 30 lb class light breakers | APT 117, CP 0112EX, Tamco TPB-30, Texas Pneumatic TX30 |
| 7/8 in. x 4-1/4 in. | Gas breaker / drill combos | Atlas Copco Cobra Combi, CP Red Hawk |
| 1 in. x 4-1/4 in. | 30–40 lb paving breakers | Tamco TPB40, APT 140 |
| 1-1/8 in. x 6 in. | 60–90 lb breakers (alternate chuck) | APT 160 and APT 190 (1-1/8 in. chuck option) |
| 1-1/4 in. x 6 in. | 60–90 lb paving breakers / jack hammers | Tamco TPB60, TPB90, Atlas Copco TEX 90 |
Choosing the Right Point for the Job
Start every break with a moil point — open a crack, then switch to a narrow chisel to run the break line where you want it. Use the 3 in. chisel to shave edges and clear broken material. Longer steel (up to 168 in.) reaches deep trench and frost work without kneeling the operator into the hole. If you’re also sizing the breaker itself, our guide to paving breaker buyer’s guide matches breaker weight to concrete thickness — a 40 lb breaker handles slab up to about 4 in., a 60 lb up to 6 in., and a 90 lb up to 9 in.
Common Questions
Are jack hammer bits universal? No. The shank must match the breaker’s chuck exactly — a 1-1/4 x 6 bit will not fit a 1 x 4-1/4 chuck. Check the chart above or your tool’s product page.
What is the difference between a moil point and a chisel? A moil point ends in a single point that concentrates force to start breaks; a chisel has a cutting edge for steering cracks, trenching, and clearing. Most crews run both on every job.
How do I make jack hammer bits last longer? Keep the shank coated with chisel paste, don’t run the breaker unloaded, and retire steel with mushroomed heads before they crack the front end.
