Osg 17543111 Taper Length Drill Bit 0.0938 in Cobalt

Product Description

The OSG 17543111 is a taper length cobalt drill bit designed for high-performance drilling in a wide range of ferrous and non-ferrous metals. Built from M-6K grade cobalt steel and finished with OSG WXL coating, this 3/32 inch (0.0938 inch) diameter bit handles demanding materials where standard HSS bits fall short. The 120-degree standard point angle and X-thinned, tapered web geometry reduce thrust at entry and improve chip evacuation. Right-hand spiral flute with a fast helix keeps cutting efficient. Machinists, tool-and-die technicians, and metalworking professionals use this bit in both CNC and manual drilling operations.

This bit is suited for production and maintenance drilling in alloy steel, carbon steel, cast iron, die steel, hardened steel, stainless steel, and aluminum. The straight shank accepts standard drill chucks, making it compatible with bench drill presses, drill motors, and machining centers without a reduction sleeve. The taper length body provides added rigidity over jobber-length bits, which is useful when drilling deeper holes that require more column support and reduced deflection.

Key Features

• M-6K cobalt construction handles hardened steel and stainless steel where HSS bits wear prematurely
• WXL finish reduces friction and extends tool life in high-feed applications
• X-thinned, tapered web lowers drilling thrust and improves centering at entry
• Fast spiral flute promotes aggressive chip evacuation in deep-hole passes
• 120-degree standard point angle suits a broad range of metal drilling applications
• Straight shank fits standard drill chucks with no adapter required

Compatibility

Designed for use in standard straight-shank drill chucks on bench drill presses, machining centers, and handheld drill motors. Suitable for drilling alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel.

Installation Notes

Secure the shank fully in the drill chuck and confirm it is centered before operation. Always use appropriate cutting fluid or coolant for the workpiece material, especially when drilling stainless or hardened steel. Inspect the cutting edges before each use and replace if chipping or dullness is present. Follow applicable shop safety standards for eye protection and workpiece clamping.
