Hertel H-81196050000 Cobalt Spotting Drill 0.1969 in

Product Description

The HERTEL H-81196050000 is a cobalt spotting drill designed for precise hole location and chamfering before full-depth drilling operations. Built from Cobalt M-35 (HSS-E), this drill delivers improved heat and wear resistance compared to standard high-speed steel, making it well-suited for harder workpiece materials and interrupted cuts. The 120-degree drill point angle supports accurate centering and self-guiding entry. With a bright, uncoated finish, the H-81196050000 runs well with most water-soluble or oil-based cutting fluids. The straight-cylindrical shank measures 0.1969 inches in diameter, and the overall length is 2.375 inches. This tool is sold as a single unit and is intended for use in drill presses, CNC machining centers, or manual machine setups.

This spotting drill is suited for general-purpose machining environments including job shops, production floors, and maintenance facilities. It is appropriate for use on ferrous and non-ferrous metals where accurate spot location is required before twist drilling or reaming operations. The single-ended design and right-hand cutting direction make it compatible with standard spindle configurations. Machinists and CNC operators working with steel, stainless, cast iron, and similar materials will find this tool fits routine spotting applications.

Key Features

• Cobalt M-35 (HSS-E) construction for improved heat and wear resistance over standard HSS
• 120-degree drill point angle for accurate centering and self-guiding hole entry
• Spiral flute design with 2 flutes and web-thinned geometry to reduce thrust and improve chip evacuation
• Bright, uncoated finish compatible with a wide range of cutting fluids
• Straight-cylindrical shank at 0.1969 inches diameter for standard chuck or collet mounting
• Right-hand cutting direction, single-ended for use in conventional spindle setups

Compatibility

Designed as a general-purpose spotting drill for use in standard drill press chucks, CNC machining center collets, and lathe tailstock tooling that accept a 0.1969-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before changing tooling. Ensure the chuck or collet is clean and properly tightened to the shank diameter before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.
