Osg 8595215 Screw Machine Drill Bit 0.0846 in Hss

Product Description

The OSG 8595215 is a screw machine length drill bit designed for precision drilling in metalworking applications. Built from high speed steel with a coated finish, this bit features a 130-degree faceted point angle and a web-thinned, tapered web configuration that reduces entry force and improves chip evacuation. The straight-cylindrical shank measures 3.00 millimeters in diameter, and the overall length is 45.00 millimeters (approximately 1.77 inches). With a 0.0846-inch (2.15 mm) cutting diameter and a flute-to-diameter ratio of 5xD, this is a high performance tool suited for machinists, tool-and-die technicians, and production drilling setups.

The OSG 8595215 is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its screw machine length profile makes it ideal for use in drill presses, CNC machining centers, and turret lathes where stub-length rigidity is required. The right hand cut, two-flute spiral design promotes controlled chip removal during through-hole and blind-hole operations in both ferrous and non-ferrous materials. This bit is sold individually and is part of OSG Series 1100.

Key Features

• 0.0846-inch (2.15 mm) cutting diameter with a tolerance of +0 to -0.014 mm for precision fitment
• 130-degree faceted point angle reduces walking and improves self-centering on entry
• Web-thinned tapered web lowers thrust requirements and improves chip flow
• High speed steel construction with coated finish for improved wear resistance
• Two-flute regular spiral design supports efficient chip evacuation in steel and aluminum
• Screw machine length (stub) profile provides increased rigidity over jobber length bits

Compatibility

Rated for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Part of OSG Series 1100. Designed as an OEM-style replacement or production drill bit for applications requiring a 0.0846-inch diameter screw machine length drill.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Secure the shank fully in the drill chuck or collet before operation and verify runout is within acceptable tolerances for the application. Always power down and de-energize the machine before changing tooling. Follow shop safety protocols and applicable OSHA standards when operating drilling equipment.
