Promax 100-04824 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The PROMAX 100-04824 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard materials. It features a 3/4 inch cutting diameter, 1 inch length of cut, and a corner radius range of 0.055 to 0.065 inches. The 4-flute, right-hand cutting geometry paired with an AlTiN coating provides heat and wear resistance at elevated cutting temperatures. The 30-degree helix angle supports efficient chip evacuation, and the center-cutting configuration allows plunge entry. This tool is built for machinists and toolmakers running CNC mills or manual vertical mills in production and job-shop environments.

This end mill is suited for profiling, slotting, and finish milling applications where a controlled corner radius is required to reduce stress concentrations on machined parts. The AlTiN coating makes it well-suited for dry or minimal-lubrication cutting in hardened steels, stainless steels, and cast iron. With a 3/4 inch shank diameter matching the cutting diameter, it seats directly in standard ER or end mill holders without a reducer. The Series 100 designation places it in PROMAX's standard coarse-pitch line for general-purpose hard-material milling.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for high-temperature cutting performance and extended tool life
• Corner radius range of 0.055 to 0.065 inches reduces part stress concentrations
• 4-flute, right-hand coarse-pitch geometry for efficient material removal
• Center-cutting design allows direct plunge milling
• 30-degree helix angle promotes chip flow and surface finish quality

Compatibility

Designed as a direct-fit replacement for 3/4 inch shank corner radius end mills in standard ER collet chucks, end mill holders, and milling machine spindles accepting 3/4 inch straight shanks.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Secure the shank in a compatible holder to the manufacturer-recommended clamping torque for the holder type in use. Inspect the cutting edges and coating for chips or wear before each use, and verify runout with a dial indicator after seating to confirm proper tool engagement.
