No. 11 (4.85mm) HSS Bright Stub Drill
Stub drills (screw machine twist drills) have a shorter overall length than Twist drills for maximum rigidity and longer tool life. 135º 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 the need for end thrust. They are designed primarily for machining operations in lathes (screw machines) but can also be used in manual hand held drills.
Bordo Stub Drills have two helical flutes with 30 degrees of helix angle. This provides fast chip ejection and very stable drilling operation.
Bright Finish Twist 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.
