Osg 17545311 Taper Length Cobalt Drill Bit 5/32 Inch

Product Description

The OSG 17545311 is a taper length cobalt drill bit designed for demanding material removal in industrial and trade applications. Built from M-6K high-performance cobalt steel, this bit carries a WXL finish and features a 120-degree split point with R-thinned web geometry for reduced thrust and cleaner entry. The straight shank accepts standard drill chucks, and the fast spiral flute promotes efficient chip evacuation. At 5/32 inch (0.1562 inches) in diameter, it delivers tight tolerances of +0.000 to -0.018 mm, making it a reliable choice for precision hole work in tough materials.

The OSG 17545311 is suited for machining and fabrication environments where hard and abrasive metals are the daily workload. Compatible material applications include alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel. The taper length body provides additional reach compared to jobber-length bits, making it useful in jig work, fixture drilling, and applications where a standard-length bit falls short. It is commonly used by machinists, tool-and-die tradespeople, and metal fabricators.

Key Features

• M-6K cobalt construction for heat resistance and extended tool life in hard metals
• WXL coating reduces friction and extends edge life in abrasion-prone materials
• 120-degree standard point with R-thinned web lowers thrust and improves centering
• Fast spiral flute type promotes rapid chip evacuation and reduces heat buildup
• Tapered web configuration adds rigidity through the body of the bit
• Right-hand cut, straight shank for use in standard drill chucks and CNC holders

Compatibility

Designed for use in drilling alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel. Fits any standard drill chuck or holder accepting a 5/32 inch straight shank. Part of the OSG Series 1750 taper length drill bit line.

Installation Notes

Installation of this bit is performed by qualified machinists or trade professionals using standard drill press, mill, or handheld drilling equipment. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits before cutting. Always wear appropriate eye protection and follow applicable shop safety protocols. Do not exceed the recommended feed and speed parameters for the material being drilled.
