Osg 17549411 Taper Length Cobalt Drill Bit 0.2969 in

Product Description

The OSG 17549411 is a taper length cobalt drill bit designed for high-performance drilling in demanding industrial and metalworking applications. Built from M-6K cobalt high-speed steel, it delivers extended tool life and heat resistance compared to standard HSS bits. The bit features a 120-degree split point angle with R-thinned web for reduced thrust and improved centering on entry. A fast spiral flute geometry promotes efficient chip evacuation. The WXL finish enhances lubricity and wear resistance. This bit is suited for professionals and production machinists who require consistent, accurate hole quality in tough materials.

The 17549411 is rated for use in alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel. Its straight shank fits standard drill chucks without adapters, making it compatible with floor-standing drill presses, CNC machining centers, and hand-held drill motors. The taper length body provides extra reach for deeper hole applications where a jobber-length bit falls short. It belongs to OSG Series 1750, a line built for demanding production environments.

Key Features

• Cobalt M-6K high-speed steel construction for heat and wear resistance in hard metals
• WXL coating improves surface lubricity and extends cutting life
• 120-degree standard point angle with R-thinned web reduces entry thrust and walk
• Fast spiral flute design accelerates chip removal in deep-hole drilling
• Straight shank fits standard chucks without a sleeve or adapter
• Tapered web configuration adds rigidity along the full flute length

Compatibility

Designed for use in standard straight-shank drill chucks on drill presses, CNC machining centers, and portable drill motors; suitable for production drilling in alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel as specified by OSG Series 1750.

Installation Notes

Installation and use should be performed by qualified machinists or tool and die professionals familiar with metalcutting operations. Secure the straight shank fully in the chuck and verify runout before beginning a cut. Follow the machine manufacturer and OSG recommended speeds and feeds for the specific workpiece material. Ensure the workpiece is firmly clamped and the spindle is powered down completely before changing or inspecting the bit.
