Promax 106-01622 Corner Radius End Mill 1/4 in 3 Flute

Product Description

The PROMAX 106-01622 is a solid carbide corner radius end mill designed for precision milling operations in metalworking applications. It features a 1/4 inch cutting diameter with a 0.02 inch corner radius, providing a controlled edge break that reduces stress concentration and extends tool life compared to sharp-corner end mills. The 3-flute, right-hand spiral design with a 35-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating adds surface hardness and lubricity, making it well-suited for ferrous and non-ferrous materials. This tool is built from micrograin solid carbide for rigidity and wear resistance at elevated cutting speeds.

This end mill fits standard CNC machining centers, vertical mills, and manual milling machines equipped with a 1/4 inch collet or end mill holder. It is a single-end, center-cutting tool, meaning it can be used for plunge cuts as well as peripheral and slot milling. The 3/8 inch length of cut and 2 inch overall length make it appropriate for shallow-to-moderate depth milling passes in dies, molds, fixtures, and general machine shop work. It is suited for use by machinists and toolmakers in production and job shop environments.

Key Features

• 1/4 inch cutting diameter with 0.02 inch corner radius for reduced edge chipping and longer tool life
• 3-flute right-hand spiral geometry with 35-degree helix angle for efficient chip removal
• TiCN coating increases surface hardness and reduces friction during cutting
• Micrograin solid carbide construction for rigidity and wear resistance
• Center-cutting design allows direct plunge entry into workpiece material
• 1/4 inch shank diameter fits standard collets and end mill holders

Compatibility

Designed for use in any CNC or manual milling machine accepting a 1/4 inch shank end mill. Suitable for Series 106 PROMAX tooling setups.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder and verify runout before beginning a cut. Follow machine manufacturer torque specifications when tightening the tool holder drawbar or collet nut.
