Osg 8692278 Solid Carbide Jobber Drill 7/64 in

Product Description

The OSG 8692278 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding metalworking applications. It carries a 7/64 inch (0.1094 inch decimal) diameter with a 140-degree point angle and an R-thinned web for improved self-centering and reduced thrust. The EgiAs coating extends tool life when cutting hard and abrasive materials. With an overall length of 78.00 mm and a flute length of 26.00 mm, this bit fits standard drill chucks via its straight-cylindrical shank. It is intended for use by machinists and metalworking professionals requiring consistent, repeatable hole quality in production environments.

This drill bit is rated for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces, covering ISO material codes P, K, S, and H. It supports blind hole drilling, cross hole drilling, and self-centering applications. The coolant-through design allows internal coolant delivery to the cutting zone, making it well suited for CNC machining centers and high-speed production setups where heat management is critical. The 5xD flute-to-diameter ratio provides adequate chip evacuation in moderate-depth holes.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating for extended tool life and reduced built-up edge
• 140-degree point angle with R-thinned web for self-centering entry and reduced thrust
• Coolant-through capable for effective heat and chip management
• Right-hand cut, regular spiral flute for reliable chip evacuation
• Straight-cylindrical shank fits standard and collet-style drill chucks

Compatibility

Part of the OSG Series 6510, designed for high-performance drilling in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces in CNC and manual machining applications.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Secure the shank fully in a collet or drill chuck before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Power down and de-energize the machine spindle before tool changes. Follow the machine manufacturer and tooling guidelines for feed rate and spindle speed when using coolant-through capability.
