Osg 8595074 Screw Machine Drill Bit No. 69 Wire Size

Product Description

The OSG 8595074 is a screw machine length drill bit sized to wire gauge No. 69 (0.0292 inches decimal equivalent) for short-reach, high-precision drilling in production and maintenance environments. Built from vanadium high speed steel and finished with a titanium nitride (TiN) coating, this bit delivers extended tool life on hard and abrasive workpiece materials. The 150-degree faceted point geometry reduces thrust and walking on entry, making it well-suited for automated equipment and hand-held drill applications where tight tolerances matter. Licensed machinists, toolroom technicians, and industrial maintenance professionals are the primary users.

This bit is designed for drilling aluminum, carbon steel, high nickel alloy, stainless steel, and titanium. The screw machine length profile — with an overall length of 38 millimeters (1.4961 inches) and a flute length of 4.50 millimeters — provides maximum rigidity in short-hole applications such as CNC drilling fixtures, turret lathes, and screw machine setups. The fast spiral flute and web-thinned, parallel web configuration improve chip evacuation and reduce torque demand in demanding production runs.

Key Features

• Wire gauge No. 69 size — 0.0292 inches decimal equivalent for precise small-diameter drilling
• Vanadium high speed steel construction rated for high-performance grade applications
• Titanium nitride (TiN) coating increases surface hardness and reduces friction at the cutting edge
• 150-degree faceted point angle minimizes thrust and improves point stability on entry
• Web-thinned parallel web reduces cutting resistance and promotes clean chip flow
• Straight-cylindrical shank (3.00 mm / 0.1181 inches diameter) fits standard collets and chucks

Compatibility

Designed as an OEM-style replacement or production-run tooling option for screw machine and CNC drilling applications requiring a wire gauge No. 69 diameter bit across aluminum, carbon steel, high nickel alloy, stainless steel, and titanium workpieces.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom technicians with all equipment powered down and locked out per applicable OSHA lockout/tagout procedures. Secure the straight-cylindrical shank firmly in a compatible collet or drill chuck to the appropriate clamping specification for the machine. Inspect the cutting edges and TiN coating before each use — chipped or worn edges on small-diameter bits can cause breakage and workpiece damage at high RPM. Consult the machine manufacturer's recommended speeds and feeds for the target workpiece material before running.
