Osg 8608182 Screw Machine Drill Bit 0.0717 in Xpm

Product Description

The OSG 8608182 is a screw machine length drill bit designed for high-performance drilling in metalworking applications. It features a 0.0717-inch (1.82 mm) diameter with a 130-degree split point angle and XPM high-performance coating over a straight-cylindrical shank measuring 3.00 mm in diameter. The spiral flute geometry is paired with an X-thinned, tapered web configuration to reduce thrust and improve chip evacuation. With an overall length of 43.00 mm and a flute length of 11.00 mm, this bit is built for close-tolerance work in production and repair environments. It is sized within the 0.0000 to 0.1000 decimal inch range of the OSG Series 1900 lineup.

This drill bit is engineered for cutting steel, alloy steel, cast iron, and nickel alloys. The screw machine length format — shorter than jobber length — provides added rigidity and reduced deflection, making it well-suited for CNC machining centers, drill presses, and screw machine operations where stub-length tools are preferred. The 3xD flute-to-diameter ratio supports efficient chip clearing in through-hole and blind-hole applications at moderate to high spindle speeds.

Key Features

• 0.0717-inch (1.82 mm) diameter with tight tolerance: +0 to -0.014 mm
• 130-degree standard point angle for self-centering entry into metal
• XPM coating for high-performance cutting on steel and hard alloys
• X-thinned, tapered web reduces drilling thrust and improves penetration
• Straight-cylindrical shank fits standard drill chucks without adapters
• Right-hand cut, 2-flute spiral geometry for consistent chip evacuation

Compatibility

Designed as a Series 1900 screw machine length drill bit for use in standard drill chucks and collets accepting a 3.00 mm straight-cylindrical shank. Primary workpiece materials include steel, alloy steel, cast iron, and nickel alloy.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified trades personnel familiar with cutting tool setup. Ensure the drill chuck or collet is clean and properly tightened before operation, and verify spindle speed is appropriate for the workpiece material and bit diameter. Never exceed the tool's rated application range for workpiece hardness. Inspect the cutting edge for wear or chipping before each use, as small-diameter bits are susceptible to breakage under side load or excessive feed pressure.
