Promax US362046 Corner Radius End Mill 3/4 in 3 Flute

Product Description

The PROMAX US362046 is a single-end corner radius end mill designed for high-performance material removal in non-ferrous metal applications. Built from micrograin solid carbide and finished with a ZrN (zirconium nitride) PVD coating, this tool delivers a tough, low-friction cutting surface suited for demanding roughing operations. The 3/4-inch mill diameter runs with a 2-inch length of cut on a 1/4-inch straight-cylindrical shank, giving machinists reach and rigidity in a compact package. Three right-hand spiral flutes with a variable helix angle and coarse pitch promote efficient chip evacuation and reduce harmonic chatter during aggressive cuts. Licensed machinists and CNC operators working in job shop and production environments are the primary users of this tool.

The US362046 belongs to PROMAX Series US362 and is built for cutting non-ferrous metals such as aluminum, brass, copper, and similar materials. Its corner radius geometry (0.060 inches) protects the cutting edge at the tool-workpiece transition, extending tool life versus a sharp-cornered end mill in the same material. The stub length type and 2.5-inch overall length make it appropriate for standard toolholder setups where minimal overhang is preferred. Center-cutting capability allows plunge entry in addition to peripheral and slot milling operations.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance
• ZrN PVD coating reduces friction and built-up edge on non-ferrous materials
• Variable helix, coarse-pitch flutes reduce chatter in roughing applications
• 0.060-inch corner radius for edge protection and improved surface finish at corners
• Center-cutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute, single-end configuration for standard CNC and manual mill setups

Compatibility

Designed for use with standard straight-bore toolholders accepting a 1/4-inch shank diameter. Primary workpiece material compatibility is non-ferrous metals (material code N).

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing any end mill. Confirm the toolholder bore is clean and free of chips before seating the shank, and tighten set screws or collet nuts to the toolholder manufacturer's specification. Verify runout at the cutting diameter after clamping before beginning a cut.
