Titan Usa SD91436 Reduced Shank Drill Bit 9/16 in Hss

Product Description

The TITAN USA SD91436 is a reduced shank twist drill bit designed for drilling through metal, wood, and plastic in professional trade applications. It features a 9/16 inch cutting diameter paired with a 1/2 inch reduced shank, allowing it to fit standard 1/2 inch chucks without requiring a larger chuck capacity. The bit is manufactured from high-speed steel (HSS) with a bright uncoated finish and ground to a 118-degree split point angle for accurate starting and clean entry. Overall length is 6 inches with a 3 inch flute length, providing adequate reach for most general-purpose drilling tasks encountered on job sites.

This drill bit is suited for use by electricians, plumbers, HVAC technicians, and general contractors who need to bore holes in sheet metal, mild steel, aluminum, wood framing, or plastic conduit and fittings. The reduced shank design is a practical solution when a larger diameter hole is needed but only a 1/2 inch chuck is available. It fits into standard 3-jaw keyed and keyless drill chucks common on corded drills, drill presses, and magnetic-base drills used across the trades.

Installation Notes

Installation is performed by a qualified tradesperson using a drill press or hand-held power drill with a 1/2 inch or larger chuck. Secure the workpiece before drilling and use cutting fluid when drilling through ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or dullness is observed. Always wear appropriate eye protection when drilling.
