Promax US362184 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The PROMAX US362184 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal applications. It features a 1/2 inch mill diameter, a 1-5/8 inch length of cut, and three flutes configured for coarse-pitch roughing operations. The tool carries a ZrN (zirconium nitride) PVD coating applied via PROMAX PowerLayer technology, which improves wear resistance and thermal stability during aggressive cutting cycles. A variable helix design reduces harmonic chatter and promotes chip evacuation. This end mill is sized for use in a straight-cylindrical toolholder and is suited for machinists and toolroom technicians working on CNC milling equipment.

The US362184 is intended for roughing passes on non-ferrous metals such as aluminum, copper, brass, and similar materials. Its center-cutting geometry allows plunge entry, making it adaptable to slot milling, ramping, and pocket operations. The long-length profile with a 4 inch overall length provides clearance for deeper workpiece features. The right-hand flute direction and right-hand cutting orientation follow standard CNC mill toolpath conventions. This tool is part of the PROMAX US362 series and is sold as a single-end tool in individual unit packaging.

Key Features

• Solid carbide micrograin substrate for rigidity and edge retention
• ZrN PVD coating via PowerLayer process for wear resistance on non-ferrous materials
• Variable helix geometry reduces chatter and improves surface finish during roughing
• Center-cutting design supports plunge entry and ramp milling
• 0.0150 inch corner radius reduces stress concentration at the cutting edge
• Coarse pitch, 3-flute configuration optimized for chip clearance in roughing cuts

Compatibility

Designed for use with straight-cylindrical toolholders. Primary workpiece material is non-ferrous metal (material code N). Part of the PROMAX US362 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Secure the shank fully within the toolholder collet or end mill holder to the manufacturer-recommended engagement depth before use. Verify runout with a dial indicator after tool change to confirm proper seating. Follow all machine guarding and PPE requirements per shop safety standards before operating.
