Drill bit for 57/64 in holes

This Chicago-Latrobe drill bit creates 57/64 in diameter holes with a 118 degree point angle. It is made from machining cobalt and carries a machining straw/bronze finish. The reduced shank allows use in chucks that cannot accept a full-size shank.

Reduced shank changes chuck compatibility

The 1/2 reduced shank lets the bit fit into smaller drill chucks that would otherwise reject a full-size shank. This extends the range of drills that can drive the bit without needing an adapter or a larger machine. The cobalt material supports drilling in harder metals.

Cobalt build handles tough metals

Machining cobalt construction resists heat and wear when cutting through steel and other hard alloys. The 118 degree point angle provides a conventional cutting profile suited to general-purpose drilling. The straw/bronze finish indicates the surface treatment applied during manufacture.

Questions about this item

Will the cobalt material on the 57/64 in drill bit need resharpening after heavy use?

The Machining Cobalt construction holds an edge longer than standard steel, so resharpening intervals are extended, but the 118 degree point can be reground when dull.

What stops the 1/2 in reduced shank from slipping in the chuck during continuous drilling?

The reduced shank fits a standard 1/2 in chuck; torque transfer is limited by chuck grip and the 118 degree point's self-centering action under load.

Does the straw bronze finish reduce heat buildup when the 53457 runs all day?

The Machining Straw/Bronze finish aids chip evacuation and provides some lubricity, helping manage temperature during prolonged drilling sessions.
