Osg 8595236 Screw Machine Drill Bit 0.0929 in Hss

Product Description

The OSG 8595236 is a screw machine length drill bit designed for high-performance metal cutting in tight-clearance applications. Built from high speed steel with a coated finish, it features a 0.0929 inch (2.36 mm) diameter, a 130-degree faceted point angle, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. With an overall length of 45 mm and a straight-cylindrical shank, this bit is engineered for use in screw machines, CNC lathes, and drill presses where compact tooling is required. The right-hand cut, two-flute spiral design suits machinists and toolroom technicians working in production or job-shop environments.

This drill bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its screw machine length profile — shorter than a jobber bit — provides added rigidity and improved hole location accuracy, making it a practical choice for high-volume drilling operations, short-run production work, and situations where chatter and deflection must be minimized. The 5xD flute-to-diameter ratio supports effective chip clearing at typical production feed rates.

Key Features

• 0.0929 inch (2.36 mm) diameter with a tolerance of +0 to -0.014 mm for precise hole sizing
• 130-degree faceted drill point with web thinning for reduced entry thrust
• Two-flute regular spiral geometry promotes clean chip evacuation
• High speed steel construction with coated finish for extended tool life on ferrous and non-ferrous materials
• Straight-cylindrical shank (3.00 mm) compatible with standard collets and drill chucks
• Screw machine length body (45 mm overall) delivers rigidity in close-quarters setups

Compatibility

Designed as an OEM-style replacement and production drill bit for screw machine, CNC lathe, and drill press applications where a screw machine length straight-shank bit in the 0.0929 inch diameter range is specified. Part of OSG Series 1100.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with cutting tool setup. Ensure spindle and workholding are fully stopped and powered down before changing tooling. Verify shank seating and collet or chuck runout before initiating a cut. Follow applicable shop safety standards and machine manufacturer guidelines for feed rate and RPM selection based on workpiece material.
