Osg 8595254 Screw Machine Drill Bit 0.1 Inch Hss

Product Description

The OSG 8595254 is a screw machine length drill bit designed for high-performance drilling in metalworking and fabrication applications. Built from high speed steel (HSS) with a coated finish, this bit runs a 130-degree faceted point angle for aggressive penetration and reduced thrust. The two-flute spiral design with a tapered web and web-thinned geometry promotes chip evacuation and improves hole entry accuracy. At 0.1 inches (2.54 mm) in diameter and 46 mm overall length, it fits standard drill presses, CNC machines, and hand-held drill motors used by machinists, tool-and-die techs, and maintenance trades.

This screw machine length bit is suited for close-tolerance drilling in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The shorter-than-jobber body improves rigidity and runout control, making it well matched for tight-tolerance work on manual mills, turret lathes, and CNC drilling centers. The straight-cylindrical shank seats securely in standard three-jaw chucks and collet holders without modification. Series 1100 positions this bit as a high-performance offering within the OSG product line.

Key Features

• 0.1 inch (2.54 mm) diameter with a tight tolerance of +0 to -0.014 mm
• 130-degree faceted drill point for fast penetration and centered starts
• Web-thinned, tapered web construction reduces axial cutting force
• Two-flute regular spiral promotes chip clearing in through-hole drilling
• Screw machine (stub) length improves stiffness and minimizes deflection
• Coated HSS construction extends tool life across ferrous and non-ferrous materials

Compatibility

Designed for use with steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Fits any standard three-jaw chuck or collet system accepting a 3 mm straight-cylindrical shank.

Installation Notes

Install and remove drill bits only after the spindle has come to a complete stop and the machine is powered down or locked out per OSHA lockout/tagout procedures. Secure the shank fully in the chuck or collet to prevent pullout under load. Use cutting fluid appropriate to the workpiece material to maintain edge life and manage heat, especially when drilling stainless steel. Inspect the cutting edges for wear or chipping before each use and replace bits that show visible damage.
