The Texas Pneumatic TX29 is a 30 lb class pneumatic sinker rock drill for pedestal-style downward drilling: anchor-bolt holes, foundation pins and small-diameter blast holes on quarry benches. A 1-1/8 in. bore delivers 2,450 BPM, the tool weighs 30 lb over an 18-1/2 in. length, and chucks come in 7/8 x 3-1/4 in. and 7/8 x 4-1/4 in. hex.

It consumes 56 CFM at 90 PSI, so a 100 CFM compressor covers one drill with margin. Both chucks take common 7/8 in. shanked drill steel stocked in Denver. The TX29 splits the difference between light chipping drills and 60 lb production models in the Texas Pneumatic rock drill lineup the rock drill buyer’s guide shows where each weight class earns its keep.
