Taper Shank Drill Bit 57/64 in

The Chicago-Latrobe 53157 is a taper shank drill bit made from high speed steel with a black oxide finish. It features a conventional 118 degree point angle for general purpose drilling. The 57/64 inch size suits applications that require this specific diameter.

Replaces worn or undersized taper shank bits

This bit upgrades from dull or smaller diameter taper shank drills when a 57/64 inch hole is needed. The 118 degree point angle is suited for general purpose work in ferrous and non-ferrous materials. The jump is worth it when the existing bit no longer cuts cleanly or the application demands this exact size.

Verify machine taper compatibility

Ensure your drill press or lathe accepts a taper shank of the correct Morse taper size for this bit. Confirm the workpiece material is appropriate for high speed steel with a conventional 118 degree point. The black oxide finish helps with chip flow and wear resistance in general purpose use.

Questions about this item

What taper shank size does the 57/64 in drill bit need to fit my machine?

The bit uses a standard Morse taper shank matched to the 57/64 inch diameter; check your spindle or sleeve for the same Morse taper number before mounting.

How do I seat the taper shank correctly and what step is often missed?

Clean both tapers thoroughly, insert the bit by hand, then drive it home with a soft-faced mallet — skipping the cleaning step causes run-out and premature wear.

When should I replace or re-sharpen the 118-degree high-speed-steel bit?

Replace or re-grind when the cutting lips show visible rounding, the black-oxide coating has worn off the flutes, or hole diameter drifts beyond tolerance.
