Pneumatic & Gas Rock Drills

Rock drills bore blast, anchor, and utility holes through hard rock and concrete with rugged percussion power. The pneumatic line leads with the APT 155, CP 0009, and Tamco/Toku TS-55, while the self-contained gas Atlas Copco Cobra Combi drills where no compressor can reach. Compare pneumatic and gas drills, or shop by brand Atlas Copco, Chicago Pneumatic, APT, Texas Pneumatic, and Toku and build the string with the right rock drill bits. New to rock drills?

Pneumatic Rock Drills

Air drills run off an air compressor sized to their demand, with rock drill oil to lube the tool and prevent freeze-ups. The APT 155, CP 0009, and TS-55 cover sinker, stoper, and plugger work; build the string with rock drill bits and steel, and see tips for efficient drilling.

Gas Rock Drills

The self-contained Atlas Copco Cobra Combi carries its own engine for remote drilling with no compressor or power pack. Gas rock drills ship at a fixed freight rate per order.

Legged and Down-Hole Drilling

For overhead and drift work, see jackleg drills and sinker drills; for deep, large-diameter holes, see down-the-hole hammers. Free shipping on every pneumatic rock drill.

Rock Drill Comparison by Weight Class

Lighter drills handle anchor and utility holes; 30–45 lb models cover general drilling; 60 lb class drills are the production sinkers. Air figures are the drill’s consumption at 90 psi — size the compressor to at least the max CFM shown.

Common Questions

What size air compressor does a rock drill need? Match the compressor’s output to the drill’s maximum CFM in the chart above — a 9 lb drill runs on as little as 20 CFM, while a 60 lb production drill needs 92–147 CFM at 90 psi. See our air compressors.

Wet or dry drilling? Wet models like the APT 155 and APT 137 flush cuttings with water and suppress silica dust; dry models use air blow. Many jurisdictions require wet drilling or dust collection on silica-bearing rock.

Gas or pneumatic? Pneumatic drills cost less to run and rebuild but need a compressor on site; the gas Cobra Combi and Red Hawk are fully self-contained for fence lines, trails, and remote rock work.

Which steel and bits fit? Match the drill’s chuck to shanked steel in rock drill bits and drill steel & bits — or see choosing drill steel and rock drill bits.
