Osg 11534815 Screw Machine Drill Bit 5/32 Inch Hss

Product Description

The OSG 11534815 is a screw machine length drill bit designed for high-performance drilling in metal fabrication and machining applications. Built from high speed steel with a coated finish, this bit measures 5/32 inch (0.1562 inches) in diameter with a 130-degree faceted drill point and a web-thinned, tapered web configuration that reduces cutting resistance at entry. The right-hand spiral flute geometry promotes efficient chip evacuation. At 54.00 mm overall length with a straight-cylindrical shank, this stub-length bit is suited for use in tight clearance drilling setups where a standard length bit would be impractical.

The 11534815 is appropriate for use on a wide range of workpiece materials including steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length format makes it a common choice for drill press, CNC, and manual machining operations where rigidity and stub-length control are required. The 3xD flute-to-diameter ratio supports controlled chip flow in shallow-to-moderate depth holes. This bit is sold individually and is a production-grade option for machinists, tool-and-die shops, and maintenance trades.

Installation Notes

Install in a drill press, CNC machining center, or hand drill with a compatible chuck rated for straight-cylindrical shanks. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck jaw condition and shank seating to prevent runout. Follow applicable shop safety procedures and machine manufacturer guidelines for feed rate and spindle speed selection based on workpiece material.
