Promax 120-01622 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The PROMAX 120-01622 is a solid carbide corner radius end mill designed for combined roughing and finishing operations in a single pass. It features a 1/4 inch cutting diameter, four flutes, and a 0.02 inch corner radius that reduces edge chipping and improves surface finish on ferrous and non-ferrous materials. The 40-degree helix angle promotes efficient chip evacuation and smoother cutting action. A TiCN coating extends tool life by increasing surface hardness and reducing friction at the cutting edge. This end mill is suited for use in CNC machining centers and manual mills where precision profiling and contouring are required.

This tool is applicable to milling operations on steel, stainless steel, cast iron, and similar materials in production and job shop environments. The corner radius end configuration makes it well suited for profiling, slotting, and peripheral milling where sharp inside corners are not required. With a 3/8 inch length of cut and 2 inch overall length, it fits short-reach applications in tight workpiece features. The 1/4 inch shank diameter is compatible with standard collet chucks and end mill holders commonly found in light to mid-size machining setups.

Key Features

• Solid carbide construction for rigidity and wear resistance
• TiCN coating for extended tool life on hard and abrasive materials
• 0.02 inch corner radius reduces edge chipping and improves workpiece finish
• 40-degree right-hand helix promotes efficient chip evacuation
• Four-flute design balances material removal rate with surface quality
• Single-end configuration with right-hand cutting direction

Compatibility

Designed as a standard 1/4 inch shank corner radius end mill compatible with collet chucks and end mill holders sized for 1/4 inch straight shanks on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the minimum recommended engagement depth in the tool holder and verify runout before beginning a cut. Follow the machine manufacturer and tooling guidelines for speeds and feeds appropriate to the workpiece material.
