Part of the Precision range of drills for the maintenance and repair professional, 331HD heavy duty jobber drills come with a steam oxide finish, preventing workpiece material from sticking to the cutting surfaces of the tool, to produce clean and accurate holes. Suitable for use in many different applications, both hand held and machine, the tools are made from High Speed Steel, meaning they can be used for drilling a range of materials including steels, aluminum and stainless steel, and have a 135 degree split point to aid self-centering and reduce the push force needed. 331HD heavy duty jobber drills are available in fractional diameters from 1/16" to 1/2" inclusive.
