BORDO METRIC QUICK SILVER M2 HSS JOBBER DRILLS DIN338

118° Split Point (crankshaft point)
Split point is self centering and reduces the need for end thrust. Friction at workpiece is reduced. 118┬║ point angles are ideal for use in materials such as mild steel and cast iron. The 118┬║ point creates easily controlled chips which are wide and thin.

DRILL BIT SURFACE TREATMENT
Bright Finish Jobber Drills have no surface treatment and are supplied in the as-ground condition. These tools are suitable for general purpose use, particularly for non-ferrous applications.
