Osg 17547211 Taper Length Drill Bit 13/64 Inch Cobalt

Product Description

The OSG 17547211 is a taper length drill bit engineered for high-performance drilling in demanding metalworking applications. Built from HSS-E cobalt steel with an M6K material grade and finished with OSG WXL coating, this bit delivers elevated heat and wear resistance compared to standard HSS tooling. The 120-degree point angle and R-thinned web reduce entry force and improve chip evacuation. The fast spiral flute design promotes efficient cutting in tough materials, making it well-suited for production environments where tool life and hole quality matter.

This bit is designed for use in stationary drill presses, CNC machining centers, and manual machines requiring a straight shank tool. Its material application range includes alloy steel, carbon steel, cast iron, hardened steel, die steel, stainless steel, and aluminum. It is appropriate for machinists, tool and die makers, and maintenance professionals working in industrial, manufacturing, and fabrication settings where tight tolerances and consistent hole geometry are required.

Key Features

• HSS-E cobalt construction with M6K material grade for superior hardness and heat resistance
• WXL coating reduces friction and extends tool life in abrasive materials
• 120-degree standard point angle with R-thinned web for reduced thrust and cleaner entry
• Fast spiral flute for efficient chip removal in deep-hole and high-feed applications
• Straight-cylindrical shank fits standard drill chucks without adapters
• Tapered web configuration adds rigidity across the flute length

Compatibility

Designed as a direct-fit taper length drill bit for standard straight-shank drill chucks and collet holders accepting a 13/64 inch shank diameter in CNC and manual drilling equipment.

Installation Notes

Installation and use should be performed by qualified machinists or tool operators familiar with cutting tool safety practices. Ensure the machine spindle is fully stopped and the chuck is properly tightened before beginning any drilling operation. Coolant through is not supported by this bit, so external coolant or cutting fluid application is recommended when drilling hardened or stainless steel. Inspect the cutting edges and coating for wear before each use and replace the bit when point geometry degrades to maintain hole tolerance.
