Osg 17546511 Extra Length Cobalt Drill Bit 3/16 in

Product Description

The OSG 17546511 is a cobalt extra-length drill bit engineered for high-performance drilling in tough materials. Built to Series 1750 standards, it features a 120-degree standard point angle and a fast spiral flute geometry that promotes aggressive chip evacuation and reduces heat buildup during extended-reach operations. The WXL finish enhances lubricity and wear resistance, extending tool life in ferrous and hard alloy applications. The straight-cylindrical shank provides consistent grip in standard drill chucks and collets. This bit is designed for use by machinists, tool and die professionals, and industrial maintenance technicians working with deep-hole or cross-drilled applications where standard-length tooling cannot reach.

The OSG 17546511 suits production and maintenance drilling in applications requiring extended reach beyond what a jobber-length bit provides. It is appropriate for metalworking environments including job shops, manufacturing facilities, and maintenance operations dealing with deep bores, stacked materials, or fixtures that limit tool access. The R-thinned web reduces entry thrust and improves centering on start. Right-hand cutting direction is standard for conventional drill press and CNC drilling setups. The 3/16 inch diameter makes it practical for bolt clearance holes, cross-drilling, and pilot operations in hardened or alloy steels where cobalt-grade tooling is required.

Key Features

• Cobalt construction (M6K grade) for elevated heat resistance in hard and abrasive materials
• WXL finish improves lubricity and extends cutting edge life
• 120-degree standard point angle for accurate entry in flat and curved stock
• Fast spiral flute promotes rapid chip evacuation in deep-hole drilling
• R-thinned, tapered web reduces thrust and improves drill stability at entry
• Straight-cylindrical shank fits standard drill chucks and collets without adapters

Compatibility

Designed as an OEM-style extra-length cobalt drill bit compatible with standard drill chucks, collet holders, and CNC spindles accepting a 3/16 inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or industrial maintenance technicians. Secure the shank firmly in a properly sized chuck or collet and verify runout before drilling. Always wear appropriate PPE and follow applicable OSHA and shop safety procedures when operating drilling equipment. Do not exceed the recommended feed and speed parameters for the work material and bit diameter.
