Osg 17544711 Taper Length Drill Bit 9/64 Inch Cobalt

Product Description

The OSG 17544711 is a taper length drill bit from the OSG Series 1750 line, manufactured from HSS-E cobalt (M6K grade) and finished with a WXL coating for extended tool life in demanding drilling applications. Sized at 9/64 inch (0.1406 inch decimal), the bit features a 120-degree standard point, a fast spiral flute, and a right-hand cut with R-thinned web geometry. The straight cylindrical shank simplifies chuck mounting. With a 50 mm flute length and 100 mm overall length, this bit is built for high-performance through-hole and blind-hole work in metal fabrication, maintenance, and precision machining environments.

The OSG 17544711 is suited for drilling alloy steel, carbon steel, cast iron, die steel, hardened steel, stainless steel, and aluminum. Its cobalt HSS-E construction and WXL coating make it a strong fit for production drilling in machine shops, fabrication facilities, and maintenance shops where tool longevity and dimensional accuracy across difficult materials are required. The tapered web configuration aids chip evacuation in longer cuts.

Key Features

• HSS-E cobalt (M6K grade) construction for heat resistance and durability in hard and abrasive metals
• WXL coating reduces friction and extends cutting life
• 120-degree standard point for accurate entry on flat and curved surfaces
• Fast spiral flute with R-thinned, tapered web for efficient chip removal
• Right-hand cut, straight cylindrical shank for compatibility with standard drill chucks
• Diameter tolerance of +0.000 to -0.018 mm for consistent hole sizing

Compatibility

Designed for drilling alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel. Fits standard drill chucks accepting a 9/64 inch straight cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by machinists or qualified trade professionals familiar with drilling speeds and feeds for HSS-E cobalt tooling. Secure the straight shank fully in a keyed or keyless chuck before operation and verify chuck runout is within acceptable limits. Use appropriate cutting fluid or coolant for the workpiece material to protect the coating and extend bit life. Do not exceed the rated speed for the material being drilled, and allow the bit to cool before handling after use.
