Promax US362402 Corner Radius End Mill 1 in 3 Flute Carbide

Product Description

The PROMAX US362402 is a solid carbide corner radius end mill engineered for material removal in non-ferrous metal applications. It features a 1-inch mill diameter, a 3.25-inch length of cut, and a 6-inch overall length with a straight cylindrical 1-inch shank. The tool carries a ZrN (zirconium nitride) PVD coating applied through PROMAX PowerLayer technology, which improves wear resistance and surface performance on aluminum, copper, brass, and similar non-ferrous workpiece materials. Three flutes with a variable helix and coarse pitch geometry drive efficient chip evacuation during roughing passes. Center-cutting capability allows plunge entry. This tool is installed by machinists and CNC programmers in production and job-shop environments.

The US362402 is intended for roughing operations on non-ferrous metals in CNC milling applications. Its long-reach geometry, 3.25-inch length of cut, and variable helix design make it suited for deep-pocket milling and profiling where standard-length tooling cannot reach. The 0.190-inch corner radius reduces corner chipping and improves tool life at depth. This end mill seats into a standard straight-bore toolholder or collet chuck compatible with a 1-inch shank diameter.

Key Features

• 1-inch mill diameter with 0.190-inch corner radius for reduced corner stress
• Solid micrograin carbide substrate for rigidity and edge retention
• ZrN PVD coating via PowerLayer process for non-ferrous material performance
• Variable helix, coarse pitch flute geometry optimized for roughing and chip evacuation
• 3.25-inch length of cut supports deep-pocket and extended-reach milling
• Center-cutting design permits direct plunge entry
• Right-hand cut, right-hand spiral, single-end configuration

Compatibility

Designed for use with standard straight-bore toolholders and collet chucks accepting a 1-inch cylindrical shank. Primary workpiece material designation is non-ferrous metal (material code N), consistent with Series US362 tooling.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's torque and runout specifications. Verify shank engagement depth meets the toolholder minimum before operation. Confirm spindle direction is set to right-hand before engaging the cut. Inspect the cutting edge and corner radius for chips or coating damage prior to each use, particularly after roughing passes at full depth of cut.
