  • Main materialHAWA
  • Extra-long reach for deep-hole drilling with 2 7/8 in maximum depth

Extra-Long Drill Bit F

This Chicago-Latrobe extra-long drill bit is sized to letter F and built from high-speed steel with a black oxide finish. It suits machinists and maintenance crews who need extended reach in steel or alloy workpieces. The 135-degree split point reduces walking and starts holes cleanly without a centre punch.

Sustained drilling behaviour

The 28-degree helix and 4xD length-to-diameter ratio promote steady chip evacuation during deep passes up to 2 7/8 in. Machining-grade high-performance steel resists softening when heat builds over long cycles. Builders who need a second flute geometry or a shorter stub-length bit should look elsewhere.
