The Tamco/Toku THD1100N is a 9 lb class handheld pneumatic rock drill for light chipping, spot drilling and small-diameter anchor holes. Its 1-1/8 in. bore delivers 3,200 BPM through a right-hand-rotation 7/8 x 3-1/4 in. hex chuck, and at 11 lb and 16-1/2 in. long it is the truck-inventory detail tool at the lightest end of the pneumatic rock drills Crowder Supply stocks.

Because it draws only 28 CFM at 90 PSI, a small utility compressor that would starve a production drill runs the THD1100N without complaint. The chuck takes standard 7/8 x 3-1/4 in. hex shanked drill steel; crews who run 3/4 in. round-shank chipping steel instead can look at the Tamco/Toku CP-9A, and our article on choosing a rock drill sorts out the weight classes.
