Promax 106-00814 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The PROMAX 106-00814 is a single-end corner radius end mill designed for precision milling in metals and hard materials. Built from micrograin solid carbide and coated with AlTiN, it delivers extended tool life and heat resistance in demanding cutting applications. The 0.010-inch corner radius produces a controlled edge blend that reduces stress concentrations in milled pockets and slots. At 1/8 inch in diameter with a 1/2-inch length of cut and 1-1/2 inches overall length, this tool is suited for fine-detail work in dies, molds, and tight-tolerance components. Installation is straightforward for machinists working on CNC mills and manual milling machines.

This end mill is used in precision machining environments including tool-and-die shops, mold making, aerospace component work, and general metalworking. The 3-flute geometry and 35-degree right-hand helix support efficient chip evacuation in ferrous and non-ferrous materials. The 1/8-inch shank diameter fits standard collets on CNC machining centers and manual mills. Its non-center-cutting design means it is intended for side milling, slotting, and profiling operations rather than direct plunge cuts.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating provides heat resistance and extended tool life in hard materials
• 0.010-inch corner radius reduces edge chipping and stress in milled features
• 3-flute, right-hand spiral design promotes efficient chip evacuation
• 35-degree helix angle improves cutting action and surface finish
• Single-end configuration; non-center-cutting for side and profile milling only

Compatibility

Designed as a Series 106 replacement or direct-use tool for CNC and manual milling machines accepting a 1/8-inch shank collet.

Installation Notes

This tool is installed by a machinist or tooling technician into a compatible collet or end mill holder. Ensure the machine spindle is fully powered down and locked before changing tooling. Verify collet size matches the 1/8-inch shank diameter and that runout is within acceptable tolerance before starting a cut. Do not use this tool for plunge cuts, as it is not center-cutting.
