A high-speed steel taper shank drill bit with a 118-degree point angle for general-purpose drilling
This Chicago-Latrobe 53204 taper shank drill bit is built for general-purpose drilling tasks. It fits machines equipped with a taper shank holder, making it suitable for machinists and maintenance technicians who need reliable hole-making in metalworking applications.
The 118 degree conventional point angle is designed for standard drilling operations across common materials. High speed steel construction with a black oxide finish helps manage heat and wear during normal use, supporting consistent cutting performance without specialised cooling requirements.
This bit requires a compatible taper shank holder or machine spindle for secure mounting. The black oxide surface treatment adds corrosion resistance, freeing the operator from frequent tool replacement in typical workshop environments. It is not intended for use with straight shank collets or quick-change systems.

Clean the machine spindle and the drill's taper shank thoroughly before inserting; the step people get wrong is leaving oil or debris on the taper which prevents a secure hold.
Resharpen the 118 degree conventional point when cutting edges dull; replace the bit once the high speed steel body wears down or the black oxide coating is gone.
Heat buildup at the 118 degree point causes the high speed steel to lose hardness fastest, leading to rapid edge wear before the taper shank or body fails.
