The Texas Pneumatic TX18 is a 14 lb class pneumatic sinker rock drill an 18 lb tool from the Texas Pneumatic percussion range that bridges light chipping hammers and 30 lb production drills. Rated 2,900 BPM on 36 CFM at 90 PSI, it handles anchor-bolt holes, foundation pins and small-diameter blast holes through a 7/8 x 3-1/4 in. hex chuck on standard contractor air.

Because the TX18 runs on 36 CFM, a 100 CFM contractor compressor powers it with capacity to spare. It shares its 7/8 x 3-1/4 in. chuck size with many light handheld rock drills, taking the same hex shanked starter rods already stocked for heavier tools, and our article on how to choose a rock drill helps you commit to a weight class with confidence.
