HSS Bright Finish Drill Refill Set 1.0-6.5mm x 0.5mm increments.
135° Split Point (crankshaft point)
Split point is self centering and the short distance from the drill axis to the outer corners results in faster penetration, reducing end thrust.
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.
