Osg 17519411 Extra Length Cobalt Drill Bit 3/16 in

Product Description

The OSG 17519411 is an extra length cobalt drill bit designed for demanding drilling applications that require extended reach and superior heat resistance. Built to Series 1750 specifications, this bit features a 3/16 inch (0.1875 inch) diameter, a 120-degree standard point angle, and OSG's WXL finish for extended tool life in tough materials. The spiral flute geometry with a fast spiral type promotes efficient chip evacuation, while the R-thinned web reduces thrust and improves penetration. It is suited for use by machinists, tool-and-die professionals, and maintenance technicians working in metal fabrication or industrial production environments.

This extra length drill bit is intended for applications where standard-length bits cannot reach, such as deep-hole drilling in structural components, fixtures, or fabricated assemblies. The 170 mm overall length and 110 mm flute length give it the reach needed for through-hole work in thicker stock. The cobalt construction (M6K material grade) handles stainless steel, high-temperature alloys, and other difficult-to-machine materials. The straight cylindrical shank seats securely in standard drill chucks and collet holders without modification.

Key Features

• Cobalt construction (M6K grade) for heat resistance in hard and abrasive materials
• WXL finish for improved wear resistance and extended tool life
• 120-degree standard point angle with R-thinned web for reduced entry thrust
• Fast spiral flute type promotes aggressive chip evacuation in deep holes
• 170 mm overall length with 110 mm flute length for extended reach applications
• Right-hand cutting direction with tapered web configuration

Compatibility

Designed as an OEM-style replacement or direct-use extra length drill bit for industrial drilling operations requiring a 3/16 inch cobalt bit with a straight cylindrical shank compatible with standard drill chucks and collet-style toolholding systems.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with drill press, CNC, or handheld drilling equipment. Secure the straight cylindrical shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Always use appropriate cutting fluid or coolant when drilling hard alloys to preserve tool life, noting this bit does not have through-coolant capability. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
