Osg 17518811 Extra Length Cobalt Drill Bit 0.1719 in

Product Description

The OSG 17518811 is an extra length cobalt drill bit designed for demanding drilling applications where standard-length bits fall short. Built from M6K-grade cobalt high-speed steel and finished with OSG WXL coating, it delivers elevated heat resistance and extended tool life when cutting through tough materials. The bit measures 0.1719 inches (11/64 inch) in diameter with a 120-degree standard point angle, a spiral flute length of approximately 3.94 inches (100 mm), and an overall length of approximately 6.30 inches (160 mm). It is intended for use by machinists, tool-and-die specialists, and metal fabricators who require reach and precision in deep-hole drilling operations.

This drill bit suits applications in metalworking, fabrication shops, and production environments where standard-length tooling cannot reach the required depth. The extra overall length makes it well-suited for drilling through thick stock, structural components, or assemblies requiring extended reach. Its right-hand cutting direction and fast spiral configuration promote efficient chip evacuation in ferrous and non-ferrous metals. The straight-cylindrical shank accepts standard drill chucks across a range of machines including drill presses, CNC machining centers, and handheld power drills.

Key Features

• M6K cobalt high-speed steel construction for heat and wear resistance in hard metals
• WXL coating reduces friction and extends tool life in high-speed cutting applications
• 120-degree standard point angle with R-thinned web for reduced thrust and cleaner entry
• Fast spiral flute geometry promotes efficient chip evacuation in deep holes
• Extra overall length of approximately 6.30 inches allows drilling beyond standard reach
• Straight-cylindrical shank compatible with standard drill chucks

Compatibility

Designed for use in standard drill chucks accepting an 11/64 inch straight-cylindrical shank. Suitable for use in drill presses, machining centers, and compatible rotary drilling equipment. Verify machine chuck capacity and spindle speed ratings before installation.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or tool operators familiar with proper speeds, feeds, and cutting fluid application for cobalt tooling. Secure the shank fully in the chuck before operation and confirm runout is within acceptable limits. Always wear appropriate eye protection and follow applicable machine guarding requirements. Do not exceed the recommended operating parameters for the workpiece material and bit diameter.
