Osg 8692680 Solid Carbide Jobber Drill Bit 6.8 Mm

Product Description

The OSG 8692680 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. It features a 6.8 mm diameter, a 140-degree R-thinned point, and an EgiAs coating for extended tool life and heat resistance. The bit runs a right-hand spiral flute with a regular spiral type, producing clean chip evacuation in blind hole, cross hole, and self-centering applications. Overall length is 109 mm with a 55 mm flute length and a 7 mm straight-cylindrical shank. This bit is installed by machinists, tool-and-die technicians, and maintenance professionals working with CNC or manual drilling equipment.

This drill bit is engineered for use on steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. It is suited to production drilling environments where tight diameter tolerances and chip control matter. The 5xD flute-to-diameter ratio makes it effective in moderate-depth blind hole operations. Coolant-through capability allows internal coolant delivery for improved chip clearing and tool life in high-cycle or deep-hole drilling scenarios.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• EgiAs coating provides thermal protection and reduced friction during cutting
• 140-degree R-thinned point for self-centering entry and reduced thrust force
• Coolant-through design supports internal coolant delivery for heat and chip management
• Tapered web with R-thinned web configuration improves cutting edge geometry
• Diameter tolerance of plus 0 to minus 0.022 mm for consistent, close-tolerance hole sizing

Compatibility

OSG Series 6510 jobber drill bit rated for steel, alloy steel, cast iron, titanium, and titanium alloys. Fits standard drill chucks and collets accepting a 7 mm straight-cylindrical shank.

Installation Notes

This bit is installed by qualified machinists or maintenance technicians using CNC machining centers, drill presses, or manual drilling equipment with appropriate chuck or collet tooling. Ensure the machine spindle is fully stopped and the tool holder is properly torqued before mounting. When using coolant-through capability, verify that the machine spindle and toolholder support internal coolant delivery before use. Inspect the cutting edge for chips or wear before each use, as carbide tooling is brittle and should not be forced into interrupted cuts beyond its rated capacity.
