Promax 120-04814 Roughing Finishing End Mill 3/4 in

Product Description

The PROMAX 120-04814 is a solid carbide roughing finishing end mill designed for high-performance material removal and surface finishing in a single tool. Built with 4 flutes and a 40-degree helix angle, it delivers aggressive chip evacuation while maintaining a quality finish. The 0.03 inch corner radius on the corner radius end profile reduces stress concentration at cutting edges, extending tool life in demanding applications. An AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures. This end mill is installed and operated by machinists and CNC programmers in production and job shop environments.

This tool is suited for milling ferrous and non-ferrous alloys, hardened steels, and aerospace-grade materials where both roughing and finishing passes are required. The single-end, right-hand cut and right-hand flute direction make it compatible with standard CNC machining centers and manual mills running conventional or climb milling operations. The 3/4 inch shank diameter fits standard ER and side-lock toolholders common in vertical and horizontal machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for high-temperature performance and extended tool life
• 0.03 inch corner radius reduces edge chipping and workpiece stress
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• 4-flute geometry balances material removal rate with surface finish quality
• Right-hand cut, right-hand flute direction for standard CNC and manual mill compatibility

Compatibility

Designed as a direct-fit replacement or new-install end mill for standard 3/4 inch collet and side-lock toolholding systems on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the tool. Seat the shank fully into the toolholder to the recommended gauge length and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut.
