Chicago-Latrobe 53165 Taper Shank Drill Bit

This Chicago-Latrobe 53165 drill bit features a 1 1/64 inch diameter and a 118 degree conventional point angle. It is manufactured from high speed steel with a black oxide finish for general purpose drilling applications. The taper shank design ensures secure fitment in compatible machine spindles or drill press sockets.

High Speed Steel Construction and Black Oxide Finish

The high speed steel material provides hardness and heat resistance suitable for drilling metal, wood and plastic. Black oxide coating reduces friction and helps resist corrosion during normal use. The 118 degree point angle delivers reliable centering and chip evacuation across common workpiece materials.

General Purpose Geometry for Standard Drilling Tasks

The conventional point geometry handles typical drilling operations without specialised tooling requirements. No bundled accessories or software accompany this individual drill bit. Users requiring different diameters, point angles or shank styles will need separate tooling.

Questions about this item

How do I install the taper shank into the spindle, and what step is often missed?

Insert the taper shank firmly into the matching taper socket and seat it with a firm tap; the step often missed is ensuring both tapers are perfectly clean before assembly.

What maintenance or replacement will this 118-degree high-speed steel bit need later?

The cutting edges will dull with use and require resharpening to the original 118-degree angle; black oxide coating wears off and does not need renewal.

What limit shows up first when drilling continuously with this 1 1/64-inch bit?

Heat buildup at the cutting edges is the first limit; high-speed steel loses hardness if overheated, so use cutting fluid and reduce feed pressure.
