Promax 106-00822 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The PROMAX 106-00822 is a solid carbide corner radius end mill designed for precision milling applications in metal fabrication and machining. The cutter features a 1/8 inch diameter with a 0.01 inch corner radius, producing smooth, controlled transitions at part edges while reducing stress concentrations in finished workpieces. A TiCN coating increases surface hardness and heat resistance, extending tool life in ferrous and non-ferrous materials. The micrograin carbide substrate supports sharper edges and tighter tolerances than standard carbide grades. This tool is installed and operated by machinists and CNC programmers working in job shops, tool rooms, and production machining environments.

This end mill is suited for light profiling, slotting, and finishing passes where a small corner radius is required at the bottom of a feature. The 1/4 inch length of cut accommodates shallow-to-moderate depth passes, and the 35-degree helix angle promotes efficient chip evacuation. The single-end, centercutting design allows for plunge entry as well as conventional peripheral cuts. Typical applications include die and mold work, aerospace components, and precision part production where edge geometry control is critical.

Key Features

• 1/8 inch cutting diameter with 0.01 inch corner radius for controlled edge geometry
• 3-flute solid micrograin carbide construction for rigidity and edge retention
• TiCN coating for improved wear resistance and reduced heat buildup
• 35-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting design enables plunge milling capability
• Right-hand cut and right-hand flute spiral for standard CNC and manual mill use

Compatibility

Designed as an OEM-style replacement and standard tooling option for 1/8 inch collet or end mill holders used in CNC machining centers, vertical mills, and similar equipment requiring a 1/8 inch shank corner radius end mill.

Installation Notes

This tool is installed by machinists using a compatible 1/8 inch collet or end mill holder. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout at the shank before cutting to stay within the specified shank diameter tolerance. Consult manufacturer feed and speed recommendations for the specific workpiece material and coating type before operation.
