Titan Usa SD92542 Reduced Shank Drill Bit 21/32 in Hss

Product Description

The TITAN USA SD92542 is a reduced shank twist drill bit machined from high speed steel for cutting through metal, wood, and general-purpose materials in production and maintenance settings. The bit measures 21/32 inch (0.6563 inch) in diameter with a 1/2 inch reduced shank, making it compatible with standard 1/2 inch drill chucks. Overall length is 6 inches with a 3 inch flute length and a 118-degree point angle. The bright, uncoated finish is typical for general-purpose HSS tooling. This is a Series 620 bit with two flutes and three flats on the reduced shank, providing positive drive and resistance to slipping in the chuck.

This bit is suited for machine shop, maintenance, and fabrication environments where a large-diameter hole is needed but only a 1/2 inch chuck is available. The reduced shank design allows the bit to be used in standard drill presses, hand drills, and benchtop machines without requiring a larger Jacobs chuck. Machinists, millwrights, pipefitters, and general maintenance technicians commonly use reduced shank bits in exactly this application. The 3 inch flute length provides adequate chip clearance for through-hole drilling in most stock thicknesses encountered in trade work.

Key Features

• 21/32 inch cutting diameter (0.6563 inch decimal equivalent)
• 1/2 inch reduced shank fits standard 1/2 inch drill chucks
• 118-degree point angle for general-purpose drilling
• High speed steel construction for durability across common work materials
• 3 flats on shank prevent chuck slippage during operation
• Bright/uncoated finish — Series 620, 2-flute design

Compatibility

Designed for use in any drill press, hand drill, or benchtop machine equipped with a 1/2 inch drill chuck. The reduced shank allows a large-diameter bit to run in a standard 1/2 inch capacity chuck without requiring an oversized spindle or specialty adapter.

Installation Notes

Secure the shank fully into the chuck jaws, engaging all three flats for maximum grip before tightening. Ensure the drill press or tool is powered off and the bit is stationary before making any chuck adjustments. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain cut quality. Always wear appropriate eye protection and secure the workpiece before drilling.
