Osg 8595228 Screw Machine Drill Bit 0.0898 in Hss

Product Description

The OSG 8595228 is a screw machine length drill bit designed for precision drilling in tight clearance applications where a shorter overall length improves rigidity and reduces deflection. Built from high speed steel with a coated finish, this two-flute bit features a 130-degree faceted point angle and web-thinned, tapered web construction for easier penetration and reduced thrust. The straight-cylindrical shank measures 3.00 mm in diameter, and the overall length is 45.00 mm (approximately 1.77 inches). It is suited for production drilling, machine tool setups, and repair work performed by machinists and maintenance technicians.

This drill bit is rated for use on a range of workpiece materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length format makes it a common choice for drill press, CNC, and hand-held machine applications where stub-length tooling is required. The regular spiral flute geometry promotes efficient chip evacuation, and the right-hand cut direction is standard for conventional drilling operations.

Key Features

• Screw machine (stub) length for improved rigidity and reduced chatter
• 130-degree faceted point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction with coated finish for extended tool life
• Two regular spiral flutes for consistent chip removal
• Right-hand cut, straight-cylindrical shank for standard chuck compatibility
• 5xD flute-to-diameter ratio supports deeper hole geometry in a compact form

Compatibility

Designed for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Compatible with standard drill chucks and machine tool spindles accepting a straight-cylindrical 3.00 mm shank.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or maintenance technician familiar with rotary cutting tool setups. Secure the shank fully in the chuck and verify runout before beginning a drilling operation. Coolant through is not supported on this bit, so external cutting fluid or lubrication should be applied as appropriate for the workpiece material. Always wear appropriate PPE when operating drilling equipment.
