Extra Long Drill Bit #34 HSS
The Chicago-Latrobe Extra Long Drill Bit #34 is made from high speed steel with a black oxide finish for machining high performance. It features a 135 degree split point designed for accurate starting and reduced walking. The bit targets wire gauge drilling tasks and suits users needing extended reach for deep holes.
Thermals noise and power draw
The high speed steel construction resists heat buildup during prolonged drilling in metal. A 135 degree split point lowers cutting force which reduces motor load and operational noise. Black oxide coating decreases friction to limit temperature rise. Maximum drilling depth is 1 1/2 in at 4xD capability.

Questions about this item
How do I install the #34 HSS drill bit correctly, and what step is often missed?
Chuck the 11158 bit securely, set the drill to low speed, and apply steady pressure; the step many miss is using cutting fluid to prevent overheating the high-speed steel.
When will the #34 extra-long drill bit need replacement, and what indicates wear?
Replace the 11158 bit when the 135-degree split point dulls, the black oxide coating wears off, or holes exceed 1 1/2 in depth and show wandering.
