Osg 17523111 Extra Length Cobalt Drill Bit 0.3438 in

Product Description

The OSG 17523111 is a high-performance extra length cobalt drill bit engineered for demanding metal-cutting applications. Built from M6K-grade cobalt steel and finished with OSG WXL coating, this bit delivers extended tool life and heat resistance in tough materials. The 0.3438 inch (11/32 inch) diameter bit features a 120-degree standard point angle with R-thinning on the web for easier penetration and reduced thrust. At an overall length of 270 mm (approximately 10.63 inches) with a 200 mm (approximately 7.87 inch) flute length, it is suited for deep-hole drilling where standard-length bits cannot reach.

This drill bit is used in professional machining, fabrication, and maintenance applications where deep-reach capability is required. The fast spiral flute promotes efficient chip evacuation, making it well suited for drilling in steel alloys, stainless, and similar ferrous materials. Right-hand cutting direction is standard for conventional drill press, CNC, and hand-held power tool setups. The straight-cylindrical shank ensures compatibility with standard drill chucks. Industrial machinists, tool-and-die tradespeople, and maintenance mechanics are the primary users of this Series 1750 bit.

Key Features

• M6K cobalt steel construction for high heat and wear resistance
• WXL coating for extended tool life in ferrous and hard materials
• 120-degree standard point with R-thinned web for reduced entry thrust
• Fast spiral flute promotes efficient chip clearing in deep holes
• Tapered web configuration adds rigidity along the flute length
• Extra length design reaches depths standard bits cannot achieve

Compatibility

Designed as an OEM-style industrial cutting tool for use in standard drill chucks accepting an 11/32 inch straight-cylindrical shank across drill presses, CNC machining centers, and hand-held power tools.

Installation Notes

Installation and use should be performed by qualified machinists or skilled tradespeople familiar with metal-cutting operations. Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation, and verify the workpiece is clamped or fixtured to prevent movement. Always use appropriate cutting fluid or coolant for the material being drilled, as this bit does not have coolant-through capability. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds.
