Osg 8623100 Extra Length Cobalt Drill Bit 0.3937 in

Product Description

The OSG 8623100 is a cobalt extra length drill bit designed for drilling operations that require extended reach beyond standard-length tooling. Built to Series 1750 specifications, it carries a WXL finish and features a fast spiral, two-flute configuration with a 120-degree standard point and R-thinned, tapered web geometry. The 0.3937-inch diameter matches a 10 mm nominal size, and the overall length of 9.843 inches gives machinists and metalworking trades the clearance needed for deep-hole applications. The straight-cylindrical shank seats securely in standard drill chucks and collet holders.

This bit is suited for high-performance metal drilling in job shop, maintenance, and production environments. The M6K-grade cobalt steel construction handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel. The WXL coating reduces friction and extends tool life in interrupted cuts and abrasive materials. Right-hand cutting direction is standard for conventional drilling setups. It is installed and used by machinists, tool-and-die workers, and industrial maintenance technicians.

Key Features

• Cobalt construction with M6K material grade for durability in hard and abrasive metals
• WXL finish reduces friction and extends cutting life
• Fast spiral, two-flute design promotes efficient chip evacuation in deep holes
• R-thinned, tapered web geometry reduces thrust force at the point
• 120-degree standard point angle suits a wide range of metalworking applications
• Extra length overall at 9.843 inches supports deep-hole and extended-reach drilling

Compatibility

Designed as an OEM-style extra length drill bit for use in standard drill chucks and collet systems accepting a 0.3937-inch straight-cylindrical shank, suitable for high-performance metalworking and maintenance drilling applications.

Installation Notes

Installation is performed by machinists and industrial maintenance technicians using standard drill press, mill, or handheld drilling equipment. Secure the shank fully in the chuck or collet before operation and verify runout before commencing a cut. De-energize and lock out all machine power before changing or inspecting tooling per applicable machine safety standards. Do not exceed the recommended feed and speed parameters for the workpiece material.
