Osg 8595153 Screw Machine Drill Bit 0.0602 in Hss

Product Description

The OSG 8595153 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, it features a 0.0602-inch (1.53 mm) diameter, a 140-degree faceted point, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 3.00 mm in diameter and seats securely in standard drill chucks and machine spindles. With an overall length of 42.00 mm and a flute length of 10.00 mm, this bit is engineered for short-reach, precision hole-making in production environments. It is installed and used by machinists, tool-and-die professionals, and industrial maintenance technicians.

This drill bit is suited for drilling into steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length format — shorter than jobber length — provides added rigidity and improved accuracy in CNC machining centers, turret lathes, and drill presses where close-tolerance, repeatable hole sizing is required. The 5xD flute-to-diameter ratio supports efficient chip clearance at typical production feed rates. It is packaged and sold individually.

Key Features

• 140-degree faceted point with web thinning for reduced entry thrust
• High speed steel construction with coated finish for extended tool life
• Screw machine length for improved rigidity over standard jobber-length bits
• Right-hand cut, 2-flute spiral design for consistent chip evacuation
• Straight-cylindrical shank compatible with standard chuck and collet systems

Compatibility

Designed for use in drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Part of the OSG Series 1100 screw machine length drill bit line.

Installation Notes

This bit is installed by machinists and maintenance technicians in drill presses, CNC machining centers, and turret lathes. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank fully in the chuck or collet to the recommended grip depth before operation. Follow facility lockout/tagout procedures and applicable OSHA machining safety guidelines when changing or inspecting drill bits.
