Promax 100-04012 Corner Radius End Mill 5/8 in 4 Flute Carbide

Product Description

The PROMAX 100-04012 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/8 inch cutting diameter, a 1-1/4 inch length of cut (LOC), and a corner radius range of 0.055 to 0.065 inches. The four-flute, right-hand cutting geometry with a 30-degree helix delivers efficient chip evacuation and a smooth finish. A titanium carbonitride (TiCN) coating increases surface hardness and wear resistance, extending tool life in demanding applications. The 5/8 inch shank diameter and 3-1/2 inch overall length (OAL) suit standard milling setups. This tool is installed by machinists and tooling professionals in CNC and manual milling operations.

The PROMAX 100-04012 is suited for coarse-pitch milling applications requiring a corner radius profile to reduce stress concentration and improve part durability. The centercutting design allows plunge entry, adding flexibility in slotting and profiling operations. Typical applications include end milling of ferrous and non-ferrous metals where edge integrity and dimensional accuracy are critical. This tool fits production machining, tool and die work, and prototype shops running general-purpose milling programs.

Key Features

• 5/8 inch cutting diameter with 1-1/4 inch length of cut for controlled material removal
• Corner radius range of 0.055 to 0.065 inches reduces edge stress and improves part finish
• TiCN coating provides increased hardness and extended wear resistance
• Four-flute, right-hand, coarse-pitch geometry for efficient chip flow
• Centercutting capability allows direct plunge entry into workpiece
• 30-degree helix angle balances cutting efficiency and surface finish quality

Compatibility

Designed as an OEM-style solid carbide corner radius end mill in the PROMAX Series 100 lineup, compatible with standard 5/8 inch milling collets and tool holders.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Secure the shank fully in a properly sized collet or end mill holder and torque to the machine tool manufacturer's specification before operation. Inspect the tool for chips or coating damage before each use. Never exceed the spindle speed and feed rate parameters appropriate for the workpiece material and tool diameter.
