Titan Usa SD91453 Reduced Shank Drill Bit 53/64 in Hss

Product Description

The TITAN USA SD91453 is a reduced shank twist drill bit machined from high-speed steel and designed for drilling through ferrous and non-ferrous metals, plastics, and wood composites. The bit carries a 53/64-inch (0.8281-inch decimal) cutting diameter with a 1/2-inch reduced shank, allowing it to run in standard 1/2-inch chuck equipment even though the cutting diameter exceeds that size. The 118-degree split-point angle is a general-purpose geometry suited to a wide range of materials. A bright, uncoated finish is standard for this Series 625 bit. Total overall length is 6 inches with a 3-inch flute length. Weight is 0.5 pounds.

This drill bit is appropriate for use in machine shops, maintenance facilities, and job sites where operators need to bore larger-diameter holes without requiring a larger chuck or dedicated drill press setup. The reduced shank design makes it practical for portable hand drills and bench drill presses equipped with 1/2-inch chucks. Machinists, millwrights, pipefitters, and general maintenance technicians commonly use reduced shank bits of this size when enlarging existing holes or drilling clearance holes for fasteners and conduit pass-throughs.

Key Features

• 53/64-inch cutting diameter (0.8281 inch decimal) on a 1/2-inch reduced shank for compatibility with standard chucks
• High-speed steel construction provides hardness and heat resistance for general-purpose metal drilling
• 118-degree point angle suits a broad range of materials including mild steel, aluminum, and plastics
• 3-inch flute length supports chip evacuation during deep-hole applications
• Bright, uncoated finish allows easy visual inspection of the cutting edge between uses
• Series 625 design with 2 flutes for balanced cutting performance

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with any 1/2-inch chuck drill press, hand drill, or milling machine spindle accepting straight-shank tooling.

Installation Notes

Install and remove this bit only with the drill or press powered off and the chuck fully released. Secure the shank firmly in the chuck and verify the bit runs true before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Wear eye protection and secure the workpiece before operation.
