American-made HSS drill in a blue anodized 3/8 diameter barrel with pocket clip to prevent rolling. Extra drills store conveniently into the handle which is well-knurled for a comfortable grip. All machined parts are made of rust-free aluminum and the chuck is made of black oxide tool steel. The chuck is pressed into the barrel so that it cannot turn and open easily, and never binds.
The chuck can take drill sizes from No. 80 (.0135) to 52 (.0635).
