Osg 8702690 Solid Carbide Jobber Drill 6.90 Mm 140 Deg

Product Description

The OSG 8702690 is a solid carbide jobber-length drill designed for high-performance drilling in demanding materials including steel, alloy steel, cast iron, titanium, and titanium alloys. It features a 6.90 mm diameter with a 140-degree point angle and an EgiAs coating for extended tool life and heat resistance. The R-thinned web reduces thrust and improves self-centering at entry. With a 5xD flute-to-diameter ratio and coolant-through capability, this drill is built for productive metal-removal in production and job-shop environments where tool consistency matters.

This drill is suited for drilling blind holes, cross holes, and standard through-hole applications in CNC machining centers and drill presses. It is used in aerospace, automotive, and general metalworking operations where hard and abrasion-resistant workpiece materials require a carbide substrate and a high-performance coating. A straight-cylindrical shank with an 8.00 mm diameter fits standard ER collet chucks and drill holders commonly used in these environments. It is appropriate for machinists and tool-room personnel working with P, K, S, and H material group classifications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating for reduced friction and improved thermal performance
• 140-degree point angle with R-thinned web for self-centering and reduced thrust
• Coolant-through design supports chip evacuation in blind-hole and deep-hole applications
• Regular spiral, 2-flute configuration for balanced cutting and chip flow
• Tapered web with 5xD flute ratio provides stability throughout the cut

Compatibility

The OSG 8702690 is rated for use in steel, alloy steel, cast iron, titanium, and titanium alloys, corresponding to ISO material group codes P, K, S, and H. It is part of OSG Series 6510 and falls within the 6.00 to 7.00 mm drill size range.

Installation Notes

Installation and use of this drill is performed by qualified machinists familiar with CNC or manual drilling operations. The straight-cylindrical shank should be seated fully and securely in a compatible collet chuck or drill holder before operation. Verify coolant-through lines are clear and delivering adequate flow before drilling coated or hardened workpieces. Do not exceed the drill manufacturer's recommended feed and speed parameters for the target workpiece material.
