Bordo 3.26mm HSS Bright Stub Drill Bit

Product Features

• Stub drills (screw machine twist drills) have a shorter overall length than Twist drills for maximum rigidity and longer tool life.
• 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 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.
