Chicago-Latrobe #57 HSS Extra Long Drill Bit
This Chicago-Latrobe drill bit is a high-speed steel accessory sized #57 with a 135-degree split point. The black oxide finish and 28-degree helix support chip evacuation in deep holes. It is made from machining-grade high-performance steel for extended tool life.
Suited for precision wire-gauge drilling in metal
Machinists needing a rigid, extra-long bit for #57 wire-size holes will appreciate the split-point start and 4xD reach. Buyers who require a larger diameter, a different point angle, or a shorter jobber-length bit should select another tool.

Questions about this item
What size drill chuck is required for the #57 shank on this extra-long bit?
A standard 1/4-inch or 3/8-inch three-jaw chuck will grip the #57 wire-gauge shank; the bit is made from high-speed steel with a black-oxide finish.
Will the 135° split point start cleanly in the harder alloys I already drill with shorter bits?
Yes, the 135-degree split point is designed for self-centring in tough materials, and the high-performance machining grade handles the same alloys as your existing HSS tooling.
