Texas Pneumatic Rock Drills
Hand-held pneumatic drills from the 9 lb TX-C9 utility hammer to the 60 lb TX60RD, each shipped with a lubricator and hose whip assembly and offered in multiple chuck sizes.
The short version
Four hand-held drills, and the choice is mostly about hole size and how much air you have. The TX-C9 is a 9 lb utility hammer drill on 20 CFM with a 1-1/4 in chuck. The TX18 and TX29 are the mid-range sinkers at 36 and 56 CFM. The TX60RD is the heavy one at 98 CFM with three chuck options. All four ship with a lubricator and hose whip assembly.

Four hand-held drills
Texas Pneumatic TX-C9 Utility Hammer Drill
The utility hammer drill: light enough for one hand, cheap enough to keep on the truck, and it runs on air a small compressor can actually supply. 1-1/4 in chuck.
9 lb · 20 CFM at 90 psi · 1-1/4 in chuck
Texas Pneumatic TX18 Rock Drill
The mid-range sinker drill and the TPT drill Crowder sells most of. Shipped with lubricator and hose whip, taking standard 7/8 x 3-1/4 steel.
36 CFM at 90 psi · 7/8 x 3-1/4 chuck · lubricator and whip included
Texas Pneumatic TX29 Rock Drill
More weight behind the blow than the TX18 and a choice of 7/8 x 3-1/4 or 7/8 x 4-1/4 steel. The step up when the rock is harder or the holes are deeper.
56 CFM at 90 psi · 7/8 x 3-1/4 or 7/8 x 4-1/4 chuck
Texas Pneumatic TX60 Rock Drill
The heavy hand-held drill in the range, in three chuck sizes so it fits whatever steel the fleet runs. 98 CFM is a real compressor requirement — check it before ordering.
60 lb class · 98 CFM at 90 psi · three chuck sizes

Rock drill questions, answered
What is the difference between a rock drill and a hammer drill?
A pneumatic rock drill is a percussive tool: it hammers the steel into the rock and indexes it between blows, and it needs a compressor behind it. A cordless or corded hammer drill is a rotary tool with a hammer action added, and it is a different class of machine for a different hole. The TX-C9 sits between the two — a light air-driven utility hammer drill for anchor holes.
How much air does each drill need?
20 CFM for the TX-C9, 36 CFM for the TX18, 56 CFM for the TX29 and 98 CFM for the TX60RD, measured at 90 psi. Those are continuous-operation figures for one tool. If the compressor you have cannot carry the drill you want, the honest answer is to buy the smaller drill or the bigger compressor — a starved drill will not produce.
Which chuck size should I order?
Match the steel you already run. 7/8 x 3-1/4 is the most common small-drill shank; 7/8 x 4-1/4 and 1 x 4-1/4 appear on heavier tools. If you are starting from scratch, 7/8 x 3-1/4 gives you the widest choice of steel and bits. Not sure what you have? Send us a photo of the shank and we will identify it.
Do the drills come with anything?
Yes — Texas Pneumatic ships the rock drills with a lubricator and hose whip assembly. You still need steel and bits; those are ordered separately and depend on your chuck size and the rock. See drill steel and bits.
Does Texas Pneumatic make jackleg or stoper drills?
No. TPT builds hand-held sinker-style drills. For jackleg, stoper and airleg drills look at the all-brands rock drills category — Atlas Copco, BTE Mid-Western and Canun cover those and we stock them.
What about drill oil?
Rock drill oil is not optional. These tools depend on oil carried in the air stream for lubrication and for sealing, and running one dry will destroy it quickly. The lubricator ships with the drill; keep it filled with a proper rock drill oil.
How fast do they ship?
Stocked drills ship the same day on orders placed by 4 PM Eastern, with free UPS Ground on most items. Call 1-888-883-5144 to confirm before a start date.
