Osg 8692310 Solid Carbide Jobber Drill Bit 3.1 Mm

Product Description

The OSG 8692310 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding materials. Built on OSG Series 6510, it features a 3.1 mm diameter with a 140-degree point angle and R-thinned web geometry that reduces thrust and improves self-centering at entry. The EgiAs coating provides enhanced wear resistance and heat dissipation, extending tool life in abrasive and hard-to-machine workpiece materials. With a straight-cylindrical shank measuring 4.0 mm in diameter and a right-hand spiral flute configuration, this bit is suited for precision production environments where consistent hole quality is required. It is typically installed and operated by machinists, tool-and-die technicians, and metalworking professionals.

This drill bit is designed for use in steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. Its 5xD flute-to-diameter ratio makes it well suited for blind hole drilling, cross hole drilling, and general through-hole applications. Coolant-through capability supports high-speed CNC machining operations where internal coolant delivery is available, helping to evacuate chips and maintain cutting edge temperature in deep or interrupted cuts.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 140-degree point angle with R-thinned web for reduced entry thrust and improved self-centering
• EgiAs coating for extended tool life in steel, cast iron, titanium, and titanium alloys
• Coolant-through design compatible with internal coolant CNC spindles
• 5xD flute length ratio suitable for blind hole, cross hole, and self-centering applications
• Straight-cylindrical shank for use in standard drill chucks and collet holders

Compatibility

Designed as an OEM-style precision drill bit for CNC machining centers and drill presses equipped with standard straight-shank toolholders accepting a 4.0 mm shank diameter within the 3.00 mm to 4.00 mm drill bit size range.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with CNC or manual drilling equipment. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify the collet or chuck bore matches the 4.0 mm shank diameter to prevent runout and premature tool wear. When using coolant-through capability, confirm that coolant pressure and flow rate are compatible with the spindle and toolholder setup before starting the cut.
