Product Identity

The Chicago-Latrobe 53162 is a general-purpose taper shank drill bit manufactured from high speed steel with a black oxide finish. It features a 118 degree conventional point angle designed for standard drilling operations in a variety of materials.

Upgrade Context

This bit replaces worn or damaged taper shank drills of the same 31/32 in size where a 118 degree point geometry is specified. The jump is worth it when the existing tool no longer cuts cleanly or when a fresh high speed steel edge is required to maintain hole accuracy.

Build Integration

The taper shank mounts directly into a compatible machine spindle or sleeve without a separate chuck, freeing up the chuck capacity for other tooling. It requires a machine equipped to accept a taper shank interface and sufficient spindle travel for the bit length.

Questions about this item

What taper-shank size does the 31/32 in drill bit need for the machine spindle?

The bit uses a standard Morse taper shank that matches the 31/32 in diameter; select the corresponding Morse taper socket in your drill press or lathe tailstock for a secure fit.

How do you seat the 118-degree conventional-point bit so it does not spin in the taper?

Clean both the bit shank and the machine socket, insert the taper fully, then give the bit a firm twist by hand to lock the Morse taper before tightening any draw-bar or sleeve.

When should the high-speed-steel black-oxide bit be resharpened or replaced?

Resharpen the 118-degree point when cutting edges dull or chip; replace the bit once the flute length is worn down or the black-oxide coating no longer prevents rust.
