Chicago-Latrobe 53158 Drill Bit
The Chicago-Latrobe 53158 is a taper shank drill bit sized at 29/32 in with a 118 degree conventional point. It is manufactured from high speed steel with a black oxide finish for general purpose drilling tasks. This bit suits machinists and maintenance technicians who need a standard Morse taper fit for larger hole diameters.
Upgrade from straight shank bits
A taper shank replaces straight shank bits when the drill press or lathe uses a Morse taper spindle, providing a self-holding seat that resists spin-out under high torque. The jump is worth it when hole sizes exceed the practical clamping range of three-jaw chucks or when rapid tool changes are required on taper-equipped machines. It does not suit portable hand drills or machines without a matching taper socket.
Build fit: taper spindle and coolant
The bit seats directly into a Morse taper spindle or sleeve, so no separate chuck or adapter is needed for machines already equipped with that interface. High speed steel construction allows use with cutting fluid or coolant to extend edge life in steel and cast iron. The black oxide surface helps retain lubricant during deep-hole drilling. It frees up chuck capacity for smaller tooling while the taper handles the large diameter.

Questions about this item
What taper-shank size fits a 29/32 in Chicago-Latrobe 53158 bit?
The bit has a Morse taper shank sized for a 29/32 in drill body; match the shank number stamped on your machine spindle or sleeve.
How do I seat the 118° point correctly in the taper socket?
Clean both taper surfaces, insert the shank fully, then give a firm twist by hand so the 118° conventional point seats before tightening the drawbar.
When should I replace the high-speed-steel 53158 bit?
Replace it when the 118° cutting lips show visible rounding, the black-oxide coating is worn through, or the bit no longer cuts cleanly at proper feed rates.
