Chicago-Latrobe 53129 Taper Shank Drill Bit
The Chicago-Latrobe 53129 is a general-purpose taper shank drill bit designed for metalworking applications. It suits machinists and maintenance technicians who need a reliable tool for drilling holes in steel and other ferrous materials using machines equipped with taper sockets.
High Speed Steel Construction and Black Oxide Finish
The bit is manufactured from high speed steel with a black oxide finish that enhances wear resistance and reduces friction during cutting. Its conventional 118 degree point angle provides effective centring and chip evacuation for standard drilling tasks, while the taper shank ensures secure mounting directly into a machine spindle or sleeve without a separate chuck.
Consistent Cutting Performance in Normal Use
The high speed steel body maintains hardness at elevated temperatures generated during continuous drilling, supporting steady material removal. The black oxide surface helps dissipate heat and resists galling, contributing to smoother operation and longer edge life under typical shop conditions.

Questions about this item
What taper shank standard does the 53129 bit use and what size range does it cover?
It uses a Morse taper shank sized for a 29/64 in drill body; the taper itself follows the standard Morse series for that diameter.
What chuck or holder is needed to mount a 29/64 in taper shank bit?
A Morse taper sleeve or socket matching the bit's taper number, or a drill press spindle with the same internal Morse taper.
How do you seat the taper shank correctly and what common mistake should be avoided?
Clean both tapers, insert the bit, and twist firmly to lock by friction; do not tap the shank with a hammer, which can damage the taper.
