Osg 17522011 Extra Length Cobalt Drill Bit 0.2812 in

Product Description

The OSG 17522011 is a cobalt extra-length drill bit engineered for demanding hole-making applications where standard-length tooling cannot reach. Built from M6K-grade cobalt high-speed steel and finished with OSG WXL coating, this bit delivers extended tool life in hard and abrasive materials. It runs a 120-degree standard point angle with R-thinned web for improved self-centering and reduced thrust at drill entry. The spiral flute geometry is fast-spiral, promoting efficient chip evacuation in deep-hole operations. At 9.248 inches overall length with a 6.457-inch flute length, this bit is well-suited to production and maintenance shops running deep bores in alloy steels, stainless, and similar tough materials.

This extra-length drill bit is designed for use in CNC machining centers, drill presses, and handheld power tools requiring a straight-cylindrical shank. It is commonly applied in metalworking environments where standard jobber-length bits lack the reach needed to complete through-holes in thick stock, weldments, or structural sections. Right-hand cutting direction makes it compatible with conventional spindle rotation. Machinists, tool-and-die professionals, and maintenance technicians working in industrial or heavy fabrication settings will find this bit appropriate for high-performance drilling cycles.

Key Features

• M6K cobalt construction for heat and wear resistance in hard metals
• WXL coating extends cutting life and reduces built-up edge
• 120-degree standard point angle with R-thinned web for accurate entry and reduced thrust
• Fast-spiral flute promotes efficient chip clearing in deep holes
• Tapered web configuration and 2-flute design balanced for rigidity and chip flow
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style replacement or direct-use extra-length drill bit for straight-chuck spindles accepting a 9/32-inch straight-cylindrical shank across compatible drill presses, machining centers, and handheld drilling equipment.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with metal-cutting tooling. Secure the straight-cylindrical shank fully in the chuck and verify runout before beginning a cut. Power down and de-energize the machine spindle before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection when using cobalt tooling in hard materials.
