Bordo 1mm HSS Black Stub Drill Bit

Product Features

• 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
• Bordo Stub Drills have two helical flutes with 30 degrees of helix angle. This provides fast chip ejection and very stable drilling operation

Applications

• They are designed primarily for machining operations in lathes (screw machines) but can also be used in manual hand held drills

Specifications

• Black Finish Stub Drills (also called blue finish) achieve their distinctive colour by steam tempering, a thermal process resulting in a porous tool coating
