Promax US362012 Corner Radius End Mill 5/8 in 3 Flute

Product Description

The PROMAX US362012 is a solid carbide corner radius end mill designed for precision milling of non-ferrous metals. It features a 5/8-inch (0.6250 inch) mill diameter, a 3/4-inch length of cut, and three flutes arranged in a variable helix spiral configuration. The ZrN (zirconium nitride) PVD coating reduces friction and improves tool life when working aluminum, copper, brass, and similar non-ferrous workpiece materials. With a short overall length of 2.5 inches and a straight-cylindrical shank, this is a single-end roughing tool suited to production machining environments where material removal rate matters. Machinists and tooling specialists are the primary users.

The US362012 fits applications involving non-ferrous metal roughing passes where a coarse pitch, variable helix geometry helps break up chip harmonics and clear material efficiently. The 0.030-inch corner radius protects the cutting edge and reduces chipping at entry and exit. The 3/16-inch shank diameter allows use in collet-style toolholders commonly found on CNC machining centers and manual knee mills. It is well suited to high-speed pocket milling, slotting, and profile cuts in aluminum alloy and similar soft metals where a ZrN-coated carbide tool outperforms uncoated tooling.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention in non-ferrous applications
• ZrN PVD coating reduces built-up edge and extends tool life in aluminum and non-ferrous cuts
• Variable helix flute geometry dampens vibration and improves surface finish during roughing
• 0.030-inch corner radius (tolerance -0.0010 to +0.0010 inch) protects the cutting edge
• Center-cutting design allows plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute spiral compatible with standard CNC spindle rotation
• Short length type minimizes deflection during aggressive material removal passes

Compatibility

Designed for use with standard straight-bore collet toolholders accepting a 3/16-inch shank diameter. Intended for non-ferrous metal workpiece materials (material code N) including aluminum alloys and similar soft metals. Part of the PROMAX Series US362 corner radius end mill family.

Installation Notes

This tool is installed by a machinist or tooling technician into a collet-style toolholder; ensure the collet bore matches the 3/16-inch shank diameter and that the toolholder is torqued to the machine manufacturer specification before running. Power down and lock out the machine spindle before changing tooling. Confirm runout with a dial indicator after seating to protect both the tool and the workpiece. Do not exceed the feed, speed, and depth-of-cut parameters recommended for solid carbide end mills in non-ferrous materials.
