Osg 859523811 Screw Machine Drill Bit 3/32 Inch Hss

Product Description

The OSG 859523811 is a screw machine length drill bit designed for high-performance drilling in a wide range of materials. With a 3/32 inch (0.0938 inch) diameter and a 130-degree four-facet point, this bit delivers clean entry and reduced walking on hard and abrasive workpiece materials. Manufactured from high speed steel with a coated finish, it carries a web-thinned, tapered web configuration that reduces cutting resistance and extends tool life. The 5xD flute-to-diameter ratio and two-flute spiral design promote efficient chip evacuation. This bit is suited for machinists, tool-and-die technicians, and fabricators working on close-tolerance drilling operations.

This screw machine length bit is used in bench drill presses, CNC machining centers, and hand-held power tools where a stub-length configuration is preferred for rigidity and reduced deflection. Its straight cylindrical shank fits standard drill chucks without adapters. The OSG Series 1100 is built for drilling into steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces in both production and maintenance environments.

Installation Notes

This drill bit is installed and serviced by machinists, tool-and-die technicians, and fabricators. Secure the straight cylindrical shank firmly in the chuck before operation and confirm the chuck is fully tightened. Always wear appropriate eye protection when drilling. Follow applicable workplace safety standards for rotating cutting tools and ensure the workpiece is clamped securely before beginning any drilling operation.
