Chicago-Latrobe 53156 Taper Shank Drill Bit
This Chicago-Latrobe 53156 is a new general-purpose taper shank drill bit made from high-speed steel with a black oxide finish. It features a conventional 118-degree point angle suited for a wide range of materials. The tool is designed for use with machines equipped to accept taper shank tooling.
Suited for 7/8 inch drilling
This drill bit suits machinists and maintenance crews needing a 7/8 inch hole using equipment that accepts a taper shank. It is not for operators whose machines require straight shank tooling or who need a different diameter. Buyers requiring specialised point geometries for hard metals or deep-hole drilling should look elsewhere.
118-degree conventional point angle
The single specification that decides fit is the 118-degree conventional point angle combined with the taper shank design. This geometry determines how the bit centres and cuts in standard ferrous and non-ferrous materials. Verify your machine spindle accepts a taper shank and that the 118-degree profile matches your application requirements.

Questions about this item
What taper-shank machine or adapter is required to hold the 7/8 in drill bit?
A machine spindle or sleeve that accepts a Morse taper matching the bit's shank is needed; the 7/8 in diameter determines the Morse taper size required for a secure fit.
Will the 118-degree conventional point work in the same materials as my existing split-point bits?
Yes, the 118-degree conventional point on this high-speed steel bit handles general-purpose drilling in steel, cast iron and wood, though it may walk more than a split-point design on hard surfaces.
How can I confirm the black-oxide finish is providing the intended lubricity during use?
Observe chip colour and ejection; consistent silver chips and smooth evacuation indicate the black-oxide coating is reducing friction and heat as designed.
