Chicago-Latrobe 53116 Taper Shank Drill Bit
The Chicago-Latrobe 53116 is a taper shank drill bit designed for general-purpose drilling in metalworking and maintenance tasks. Its 1/4 inch size and standard Morse taper fit directly into compatible drill presses and lathe tailstocks without a separate chuck. The high-speed steel construction provides the hardness and heat resistance needed for cutting ferrous and non-ferrous materials. This tool suits machinists and maintenance technicians who require reliable holemaking in a workshop environment.
Sustained cutting performance
The black oxide surface treatment helps retain cutting fluid and reduces chip welding during extended drilling cycles. High-speed steel maintains its temper at the temperatures reached in continuous operation, allowing the 118 degree conventional point to stay sharp longer than carbon steel alternatives. The taper shank seats securely in the machine spindle, minimising run-out that can worsen under load. Consistent feed pressure and proper lubrication keep the bit cutting efficiently through deeper holes.
Upgrading from carbon steel or straight-shank bits
This bit replaces carbon steel drills that dull quickly in steel or cast iron, and it eliminates the need for a drill chuck when used in taper-socket machines. The jump is worthwhile for users drilling harder alloys or producing higher volumes of holes where tool life and rigidity matter. It is not suited for handheld drills lacking a taper socket, for very large diameter holes beyond the 1/4 inch capacity, or for applications requiring specialised point geometries such as split-point or parabolic flute designs.

Questions about this item
Does the 118 degree point angle on the 53116 bit generate more heat during extended drilling sessions?
The 118 degree conventional point is a standard geometry for general-purpose drilling and does not inherently produce more heat than other common angles under normal use.
What taper shank size must my drill press or lathe accept for the 53116 bit to seat properly?
The bit uses a taper shank; you need a machine spindle or sleeve with the matching Morse taper size for secure mounting.
Will the high-speed steel and black oxide finish on the 53116 bit hold up when drilling older, work-hardened steel parts?
High-speed steel with a black oxide finish is designed for general-purpose metal drilling and resists wear on typical ferrous materials including harder steels.
