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.

Questions about this item
How much heat does the 135-degree split point generate when drilling all day?
The 135-degree split point on this high-speed steel bit reduces thrust and heat build-up during extended drilling in tough materials.
What shank type does the F-size bit need to fit my drill chuck?
The bit has a straight shank sized for standard drill chucks that accept letter-gauge F diameters.
