Chicago-Latrobe 53140 Taper Shank Drill
The Chicago-Latrobe 53140 is a high-speed steel taper shank drill bit designed for general-purpose drilling tasks. Its 118-degree conventional point angle suits a wide range of materials including steel, cast iron and non-ferrous metals. The black oxide finish adds corrosion resistance and helps retain lubricant during operation. This tool targets machinists and maintenance technicians who need reliable hole-making in workshop environments.
Fits Standard Taper Shank Holders
The taper shank design seats directly into matching machine spindles, sleeves or drill press sockets without a separate chuck. This self-holding interface transmits high torque efficiently and reduces runout compared to straight-shank bits in collets. It frees up the chuck for other tooling and allows quick changes on equipment fitted with Morse taper spindles. The bit is not suited for handheld drills or three-jaw chucks lacking a taper adapter.
Black Oxide Finish Reduces Wear
The factory-applied black oxide coating lowers friction and improves chip flow, which extends edge life in repetitive drilling cycles. It also provides a degree of rust protection during storage between jobs. No additional coatings, coolant systems or specialised sharpening jigs are included with the bit. Users must supply their own cutting fluid and resharpening equipment to maintain performance over time.
