Promax 117-01212 Roughing Finishing End Mill 3/16 in Carbide

Product Description

The PROMAX 117-01212 is a solid carbide roughing and finishing end mill designed for aggressive material removal and smooth surface finishing in a single tool. Built with 3 flutes and a chipbreaker geometry, it reduces cutting forces and clears chips efficiently during high-feed operations. The 0.01-inch corner radius provides edge strength at the tip while maintaining tight corner tolerances. A TiCN coating adds surface hardness and lubricity, extending tool life in ferrous and non-ferrous materials. This end mill suits machinists and toolroom operators running milling operations on CNC machining centers and manual knee mills.

This end mill is suited for roughing passes that transition directly into finishing cuts without a tool change. The 3/16-inch diameter and 5/8-inch length of cut make it appropriate for slotting, profiling, and pocketing in tight geometries. The 35-degree helix angle promotes efficient chip evacuation and smooth cutting action. It is a single-end tool with right-hand flute direction and right-hand cutting direction, standard for conventional CNC milling setups in job shops and production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance
• TiCN coating increases surface hardness and reduces friction during cutting
• Chipbreaker geometry lowers cutting forces and improves chip control
• 3-flute design balances chip clearance and cutting edge count for roughing and finishing
• 0.01-inch corner radius strengthens the cutting edge and reduces chipping at corners
• 35-degree helix angle promotes smooth chip evacuation

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting 3/16-inch shank diameter end mills.

Installation Notes

Installation and use of this end mill should be performed by qualified machinists or toolroom personnel. Secure the shank in a compatible collet or end mill holder rated for the shank diameter before powering the spindle. Verify spindle speed and feed rate settings against manufacturer recommendations for the workpiece material before beginning a cut. Inspect the cutting edges for wear or chipping before each use and replace the tool if damage is observed.
