Osg 17548811 Taper Length Drill Bit 17/64 in Cobalt

Product Description

The OSG 17548811 is a taper length cobalt drill bit designed for high-performance drilling in tough ferrous and non-ferrous materials. At 17/64 inch (0.2656 inches) in diameter, it features a 120-degree point angle, a fast spiral flute, and OSG WXL surface treatment for extended tool life and reduced friction. The straight shank and tapered web configuration make it a reliable choice for production drilling in machine shop and fabrication environments. Licensed machinists, toolroom operators, and CNC setup technicians are the primary installers and operators of this bit.

This drill bit is suited for taper-length drilling applications where a longer flute is needed beyond a jobber-length bit but a full aircraft-extension length is unnecessary. The 90.00 mm flute length and 140.00 mm overall length position it well for deeper hole entry in workpiece materials including alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel. It is used in both manual drill press setups and CNC machining centers where consistent, repeatable hole quality is required.

Key Features

• Cobalt construction with M-6K material grade for heat and wear resistance in hard materials
• WXL finish reduces friction and extends tool life across a wide range of materials
• 120-degree standard point angle with R-thinned web for easier entry and reduced thrust
• Fast spiral flute promotes efficient chip evacuation in deep drilling applications
• Straight shank at 17/64 inch fits standard drill chucks and collets without adapters
• Diameter tolerance of +0.000 to -0.022 mm ensures consistent hole sizing

Compatibility

Designed for use in drill presses, lathes, and CNC machining centers accepting a straight shank at 17/64 inch. Compatible material applications include alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel per OSG Series 1750 specifications.

Installation Notes

This bit is installed and operated by machinists or trained CNC technicians. Always secure the shank fully in the chuck or collet and verify runout before beginning a drilling cycle. Power down and lock out the machine before changing tooling. Do not exceed the recommended feed and speed parameters for the workpiece material, and ensure adequate coolant or cutting fluid is applied when drilling hardened or stainless steel.
