Designed for the maintenance and repair professional for use in a wide range of hand held and machine applications, 311SM screw machine length drill bits come in wire gauge sizes from 60 to 1 and are manufactured from High Speed Steel so can be used for drilling many different materials including steels, stainless steel and aluminum. They have a 135 degree split point which reduced the push force needed and helps with self-centering – and no more wandering all over the surface of the workpiece, and to ensure a clean and accurate hole, 311SM drills from Precision have a steam oxide finish to prevent workpiece material from sticking to the cutting surfaces of the drill.
