Osg 8595241 Screw Machine Drill Bit 0.0949 in Hss

Product Description

The OSG 8595241 is a screw machine length drill bit designed for high-performance drilling in metalworking applications. Built from high speed steel with a coated finish, this bit features a 130-degree faceted drill point and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 3.00 millimeters in diameter, and the overall length is approximately 1.81 inches (46.00 mm). With two spiral flutes and a regular spiral type, this bit is suited for machinists, tool-and-die workers, and production drilling setups requiring a compact, stub-length geometry.

This drill bit is intended for use on a range of workpiece materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length format provides increased rigidity compared to jobber-length bits, making it well suited for drill press, CNC, or manual machine tool use where shorter reach and reduced deflection are priorities. The flute-to-diameter ratio of 5xD and right-hand cut direction are standard for conventional drilling operations in light to heavy industrial environments.

Key Features

• High speed steel construction with coated finish for wear resistance on ferrous and non-ferrous materials
• 130-degree faceted drill point for clean entry and reduced walking on hard surfaces
• Web-thinned tapered web reduces axial thrust and improves chip flow
• Screw machine length for increased rigidity and reduced deflection in tight setups
• Two spiral flutes with regular spiral type for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as an OEM-style screw machine length drill bit in the OSG Series 1100 line, suitable for use with standard straight-shank drill chucks and collets on drill presses, lathes, and CNC machining centers requiring a stub-length bit in the 0.0000 to 0.1000 decimal inch size range.

Installation Notes

Installation and use should be performed by qualified machinists or tool operators familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and power is disconnected before changing or securing the bit in the chuck or collet. Verify shank diameter compatibility with the holding device before use, and inspect the cutting edges for damage prior to each operation.
