Chicago-Latrobe 53154 Taper Shank Drill
This Chicago-Latrobe 53154 drill bit features a 27/32 in diameter and a 118 degree conventional point angle. It is manufactured from high speed steel with a black oxide finish. The taper shank design fits directly into compatible machine spindles. It serves general purpose drilling tasks in metalworking and maintenance applications.
Replaces worn or damaged taper shank bits
The upgrade is worth it when an existing bit shows dull cutting edges, chipped lips or excessive runout that affects hole accuracy. A fresh high speed steel bit restores cutting speed and reduces thrust force required. It suits shops standardising on 118 degree geometry for mixed materials. Users needing split point or cobalt grades for harder alloys should look elsewhere.
Practical limits of taper shank interface
The Morse taper shank relies on friction drive, so torque capacity depends on spindle cleanliness and taper condition. Heavy feeds or interrupted cuts can cause the bit to spin in the socket. The 118 degree point requires more centring pressure than split point designs. Black oxide coating aids chip flow but offers limited wear resistance in abrasive materials.

Questions about this item
What taper-shank size does the 53154 drill bit require in the machine spindle?
The 53154 bit uses a Morse taper shank that matches the drill's 27/32 inch diameter; the machine spindle must accept the corresponding Morse taper number for a secure fit.
How is the 53154 bit installed, and what step is often missed?
Insert the taper shank fully into the spindle, then seat it with a firm tap on a soft drift; the step often missed is verifying full contact by checking that the tang engages the drive slot.
When will the 118-degree point on the 53154 need re-sharpening or replacement?
Re-sharpen the 118-degree conventional point when cutting edges show wear or chip load increases; replace the high-speed steel bit if the web thickness is reduced beyond safe limits or the black oxide coating is gone.
