DORMER PRAMET 6480986 Mechanics Length Drill Bit 5/16 in High Speed Steel

For a versatile product with a tri-flat shank, suitable for the many different machine and hand held applications of the maintenance and repair professional, 321MD heavy duty jobber drills have a 135 degree split point to help keep the drill centered on the hole and reduce the push force needed to drill into the workpiece. They are manufactured from High Speed Steel for drilling all types of steel, and have a dual steam oxide finish which prevents workpiece material from sticking to the cutting surfaces of the drill for cleaner, more accurate holes, and also helps with identification. 321MD heavy duty jobber drills are available in many fractional diameters from 1/16 inch up to 1/2 inch.
