Osg 8622860 Taper Length Cobalt Drill Bit 0.2362 in

Product Description

The OSG 8622860 is a taper length cobalt drill bit designed for high-performance drilling in demanding metalworking applications. It measures 0.2362 inches in diameter with a 120-degree point angle and features a fast spiral flute for efficient chip evacuation. The WXL finish improves surface hardness and lubricity, extending tool life in tough materials. The straight shank and R-thinned web reduce thrust requirements at the point, making entry cleaner and more consistent. This bit is sold individually and is suited for machinists, tool-and-die technicians, and fabricators working in production or job-shop environments.

This drill bit is built for use in alloy steel, carbon steel, cast iron, stainless steel, hardened steel, die steel, and aluminum. The taper length body provides added rigidity over jobber-length bits when drilling deeper holes where deflection is a concern. The cobalt M-6K grade substrate retains hardness at elevated cutting temperatures, making it appropriate for materials that generate significant heat during machining. It is suited for use in drill presses, CNC machining centers, and manual milling machines where straight-shank tooling is compatible.

Key Features

• Cobalt M-6K grade substrate retains hardness at elevated temperatures for use in hard and abrasion-resistant materials
• WXL finish provides enhanced surface hardness and lubricity to extend tool life
• 120-degree standard point angle suits a wide range of metalworking applications
• Fast spiral flute geometry promotes efficient chip evacuation in deep-hole drilling
• R-thinned web reduces point thrust and improves hole entry accuracy
• Tapered web configuration adds rigidity along the flute length

Compatibility

Compatible with alloy steel, carbon steel, cast iron, stainless steel, hardened steel, die steel, and aluminum workpieces. Fits any standard straight-shank drill chuck accepting 0.2362-inch shank diameter tooling.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians. Secure the straight shank fully in a compatible chuck before operation and verify runout is within acceptable limits. Always use appropriate cutting fluid or coolant for the workpiece material, particularly when drilling stainless or hardened steel. Inspect the cutting edges for wear before each use and replace the bit when point geometry degrades to maintain hole tolerance.
