Osg 8595237 Screw Machine Drill Bit 0.0935 in Hss

Product Description

The OSG 8595237 is a screw machine length drill bit designed for high-performance drilling in metal and non-ferrous materials. Built from high speed steel (HSS) with a coated finish, this bit measures 0.0935 inches (wire size #42, 2.38 mm) in diameter with a 130-degree faceted point angle optimized for fast, accurate starts on steel, stainless steel, aluminum, and aluminum alloy. The short screw machine length body reduces deflection and improves rigidity in drill press and CNC applications. A tapered web with web thinning lowers thrust force and improves chip evacuation. Licensed machinists, tool-and-die techs, and maintenance mechanics are the typical end users.

The OSG 8595237 Series 1100 drill bit is suited for production drilling and precision machining operations where a stubby, rigid bit is required. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The right-hand spiral flute geometry and straight-cylindrical shank make it compatible with standard drill presses, CNC machining centers, and manual hand drills equipped with a standard 3-jaw chuck. The 5xD flute-to-diameter ratio supports chip clearance in deeper hole applications at this diameter range.

Key Features

• Wire size #42 (0.0935 inches / 2.38 mm diameter) with a diameter tolerance of +0 to -0.014 mm
• 130-degree faceted point angle with web thinning for reduced thrust and cleaner entry
• High speed steel construction with coated finish for extended tool life
• Screw machine length body (46.00 mm overall) minimizes deflection and improves hole accuracy
• Right-hand cut, 2-flute spiral design with tapered web for efficient chip evacuation
• Straight-cylindrical shank (3.00 mm) fits standard chucks without adapters

Compatibility

Designed for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Fits any standard drill press, CNC machining center, or handheld drill accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Do not exceed the recommended surface footage for HSS tooling in the target material. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
