Osg 8595336 Screw Machine Drill Bit 0.1323 in Hss

Product Description

The OSG 8595336 is a screw machine length drill bit designed for high-performance drilling in metalworking applications. Built from high speed steel with a coated finish, it features a 130-degree faceted point angle and a web-thinned, tapered web configuration for reduced thrust and improved chip evacuation. The straight-cylindrical shank measures 4.00 millimeters in diameter, and the overall length is 52.00 millimeters (approximately 2.05 inches). The 0.1323-inch (3.36 mm) cutting diameter carries a tolerance of +0 to -0.018 mm. With two spiral flutes and a flute-to-diameter ratio of 5xD, this bit is suited for short, rigid setups where accuracy and repeatability matter. Licensed machinists, toolroom technicians, and production drill press operators are the primary users.

This drill bit is engineered for use in screw machine and production drilling operations where a compact overall length reduces deflection and improves hole quality. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The regular spiral flute geometry and high-performance grade rating make it appropriate for both manual drill press work and CNC machining centers where short, stubby tooling is specified. Coolant-through capability is not present on this tool.

Key Features

• 0.1323-inch (3.36 mm) cutting diameter with +0 to -0.018 mm tolerance
• 130-degree faceted point angle for accurate self-centering entry
• Web-thinned, tapered web reduces thrust and improves chip flow
• High speed steel construction with coated finish for wear resistance
• Screw machine length body for rigidity in close-tolerance drilling setups
• Right-hand cut, two-flute spiral configuration for standard drilling operations

Compatibility

Rated for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Fits any spindle or chuck accepting a 4.00 mm straight-cylindrical shank.

Installation Notes

Install in a drill press, lathe turret, or CNC spindle with a collet or drill chuck sized for a straight-cylindrical shank. Ensure the workpiece and fixture are secured before initiating the cut. Follow machine manufacturer RPM and feed recommendations for the workpiece material. Inspect the cutting edge and coating for wear before each use; a damaged point will affect hole-size accuracy and surface finish.
