Osg 8702680 Solid Carbide Jobber Drill Bit 6.8 Mm

Product Description

The OSG 8702680 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding metalworking applications. It features a 6.8 mm diameter with a 140-degree point angle and an R-thinned point for self-centering entry and reduced thrust. The EgiAs coating extends tool life when cutting abrasive and hard materials. With an overall length of 109 mm and a flute length of 55 mm, this bit fits standard drill chucks via its 8 mm straight-cylindrical shank. It is suited for machinists, tool-and-die tradespeople, and production drilling operations requiring consistent, repeatable results in ferrous and exotic alloys.

This drill bit is rated for primary workpiece materials including steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. It supports blind hole drilling, cross-hole drilling, through drilling, and self-centering applications. The 5xD flute-to-diameter ratio and coolant-through design make it well suited for deep drilling cycles in CNC machining centers and manual machine tools where chip evacuation and heat management are critical. It belongs to the OSG Series 6510 high-performance carbide drill family.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• EgiAs coating for extended tool life and reduced built-up edge in steel and cast iron
• 140-degree point angle with R-thinned web for self-centering and reduced entry thrust
• Coolant-through design supports chip evacuation and heat control in deep drilling cycles
• 5xD flute-to-diameter ratio suitable for blind holes and cross-hole applications
• Right-hand spiral flute with tapered web configuration for consistent chip flow

Compatibility

Designed for use in CNC machining centers and conventional drill presses capable of accepting an 8 mm straight-cylindrical shank. Rated for steel, alloy steel, cast iron, titanium, and titanium alloy workpieces per ISO material classifications P, K, S, and H.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with carbide tooling requirements. Secure the straight-cylindrical shank firmly in a collet or chuck rated for the shank diameter before operation. Coolant-through capability should be connected to an appropriate coolant supply to maximize tool life and chip evacuation. Inspect the cutting edge and coating before each use — carbide is brittle and susceptible to chipping if dropped or improperly handled.
