Osg 8673160 Solid Carbide Jobber Drill Bit 11.6 Mm

Product Description

The OSG 8673160 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. Built to Series 6310 specifications, it features a 140-degree point angle with R-thinned web geometry that reduces thrust and improves self-centering at entry. The EgiAs coating extends tool life in demanding applications. At 11.6 mm in diameter with a 71 mm flute length and 118 mm overall length, this bit is sized for productive reach in jobber-class drilling tasks. It is suited for machinists, toolroom technicians, and production drilling operations requiring consistent hole quality in steel and cast iron.

This drill bit is intended for use in CNC machining centers, drill presses, and manual machine tools where blind hole, cross hole, and through-hole drilling are required. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. Primary workpiece materials include steel, alloy steel, and cast iron, making it a practical choice for general metalworking and job shop environments. The straight-cylindrical shank at 12 mm diameter seats securely in standard drill chucks and collet holders.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• EgiAs coating provides enhanced lubricity and extended cutting life
• 140-degree point angle with R-thinned web for reduced entry thrust and self-centering
• Regular spiral flute with tapered web configuration for controlled chip flow
• Right-hand cut with two flutes; suitable for blind hole, cross hole, and self-centering applications
• Diameter tolerance of plus 0 to minus 0.027 mm for consistent hole sizing

Compatibility

Designed as a Series 6310 OSG jobber-length drill for use in standard drill chucks and collet systems accepting a 12 mm straight-cylindrical shank; rated for steel, alloy steel, and cast iron workpiece materials with P, K, and H material group classifications.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with cutting tool setup procedures. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Coolant-through is not supported on this tool; apply external coolant or cutting fluid as appropriate for the workpiece material and cutting parameters. Follow all machine guarding and PPE requirements per applicable shop safety standards.
