Drill Bit for General Purpose Drilling
The Chicago-Latrobe 53160 is a taper shank drill bit sized at 15/16 in with a 118-degree conventional point. It is made from high speed steel with a black oxide finish for general purpose drilling tasks. The taper shank design allows direct mounting into compatible machine spindles or sleeves without a separate chuck.
Thermals Noise and Power Draw in Normal Use
High speed steel construction manages heat during standard drilling operations in metal and wood. The black oxide surface treatment helps reduce friction and heat buildup at the cutting edges. Noise and power consumption depend entirely on the driving machine and the workpiece material being drilled.
Build Quality and Mounting Implications
The black oxide coating provides corrosion resistance and helps retain cutting fluid during use. A 118-degree conventional point suits a wide range of common materials without specialised geometry. The taper shank requires a matching Morse taper socket or sleeve in the drill press or lathe for secure, concentric mounting.

Questions about this item
How do I install the 53160 15/16 in drill bit and what step is often missed?
Insert the Morse taper shank into a matching spindle or sleeve, then seat it firmly with a soft mallet; the step often missed is cleaning both tapers completely so the bit self-locks and runs true.
What maintenance or replacement will the 53160 high-speed steel bit need later?
Resharpen the 118° conventional point when cutting edges dull; replace the bit once the flute length shortens past useful depth or if the black oxide coating wears through and corrosion appears.
What limit shows up first on the 53160 bit under sustained drilling?
Heat buildup at the 118° point softens the high-speed steel, causing rapid edge wear and loss of hole accuracy before the shank or flute structure fails.
