Promax 117-01612 Roughing Finishing End Mill 1/4 in

Product Description

The PROMAX 117-01612 is a solid carbide roughing finishing end mill designed for aggressive material removal followed by a quality surface finish in a single tool. Built with 3 flutes and a chipbreaker geometry, it reduces cutting forces and controls chip evacuation during heavy cuts. The corner radius end profile measures 0.02 inches, protecting the cutting edge from chipping at the corners. A 35-degree helix angle promotes smooth cutting action, and the TiCN coating adds surface hardness and wear resistance for extended tool life in ferrous and non-ferrous applications.

This end mill suits CNC machining operations in job shops and production environments where machinists need to rough and finish in fewer passes. The 0.75 inch length of cut and 2.5 inch overall length make it well matched to shallow-to-moderate-depth pocketing, slotting, and profiling operations on milling machines and machining centers. It is a single-end tool with right-hand cutting direction and right-hand flute direction, standard for conventional and climb milling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance
• Chipbreaker geometry reduces cutting forces and improves chip control
• 0.02 inch corner radius protects cutting edges and reduces stress concentration
• TiCN coating increases surface hardness and extends tool life
• 35-degree helix angle promotes smooth, efficient cutting action
• Single-end design with right-hand cut and right-hand flute direction

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC milling machines and machining centers accepting a 1/4 inch straight shank end mill with ER or collet-style toolholders.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the toolholder. Seat the shank fully into the collet or toolholder to the recommended minimum engagement depth before tightening. Verify runout with a dial indicator after installation and before beginning a cutting operation.
