Osg 8667260 Solid Carbide Jobber Drill Bit 2.6 Mm

Product Description

The OSG 8667260 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to Series 5210 specifications, it features a 2.6 mm diameter, a 140-degree drill point angle, and a WXL coating for extended tool life and reduced friction in difficult-to-machine materials. The straight-cylindrical shank measures 3.0 mm in diameter and seats securely in standard drill chucks and collets. With coolant-through capability and a regular spiral flute geometry, this bit is suited for CNC machining centers and production drilling environments where heat management and chip evacuation are critical. Machinists and toolroom professionals specify this bit for precision work in steel, stainless, cast iron, and high-temp alloys.

The OSG 8667260 is rated for primary workpiece material groups P, M, K, and S — covering carbon and alloy steels, stainless steels, cast irons, and heat-resistant superalloys. The 5xD flute-by-diameter ratio makes it well suited for moderate-depth holes in production environments. Its overall length of 78.0 mm and flute length of 24.0 mm are consistent with jobber-length standards used in vertical machining centers, drill presses, and multi-axis CNC equipment. The two-flute, right-hand spiral design promotes efficient chip removal in both through-hole and blind-hole applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• WXL coating reduces friction and extends cutting edge life in steel and superalloy applications
• 140-degree drill point angle for reduced thrust and improved centering on hard materials
• Coolant-through design supports high-pressure internal coolant delivery for heat control
• Straight-cylindrical shank compatible with standard collet chucks and drill holders
• Right-hand, regular spiral flute geometry promotes consistent chip evacuation

Compatibility

Designed as a jobber-length replacement or production drill for CNC machining centers and drill presses requiring a 2.6 mm solid carbide bit with a 3.0 mm straight-cylindrical shank and coolant-through capability in the OSG Series 5210 range.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool changer or chuck is de-energized before inserting or removing the bit. Use a calibrated collet or precision drill chuck sized for the 3.0 mm shank to maintain runout within tolerance. Follow the machine tool manufacturer and OSG tooling recommendations for speeds, feeds, and coolant pressure appropriate to the workpiece material.
