Chicago-Latrobe 53176 taper shank drill
The Chicago-Latrobe 53176 is a new high-speed steel drill bit designed for general-purpose drilling tasks. It features a 1 3/16 inch diameter and a standard 118-degree conventional point angle. The black oxide finish provides corrosion resistance and helps retain lubricant during operation. This tool suits machinists and maintenance crews requiring reliable hole-making in metal.
Morse taper shank fits machine spindles
The taper shank seats directly into a compatible machine spindle or sleeve without a separate chuck. This interface transmits torque securely and allows quick bit changes in a drill press or lathe. It frees the user from tightening three-jaw chucks and reduces run-out compared to straight-shank bits. The shank requires a matching Morse taper socket in the equipment.
1 3/16 inch diameter for large holes
The bit produces a 1 3/16 inch hole in a single pass through steel, cast iron and similar ferrous materials. The 118-degree point centres well on flat surfaces but may walk on curved or hardened stock without a spot drill. High-speed steel wears faster than cobalt or carbide when drilling abrasive alloys or stainless steel. It is not suited for masonry, wood or composite materials.

Questions about this item
How deep can the 1 3/16 in drill bit cut before chip clearance becomes the limiting factor?
The 118-degree conventional point and black oxide coating on high-speed steel are designed for general-purpose drilling, but the maximum efficient depth depends on the material being drilled and the feed rate used.
Does the high-speed steel body overheat during continuous drilling in steel?
High-speed steel retains hardness at elevated temperatures, and the black oxide finish helps reduce friction, though sustained heavy use will still generate heat that requires proper cutting fluid and periodic withdrawal.
What taper-shank holder or machine spindle is needed to mount this bit?
The bit uses a standard taper shank that fits matching Morse taper sockets or sleeves in drill presses, lathes, or milling machines with the corresponding taper size.
