Promax 120-01022 Roughing Finishing End Mill 4 Flute Ticn

Product Description

The PROMAX 120-01022 is a solid carbide roughing finishing end mill designed for aggressive material removal with a quality surface finish in a single operation. Built to Series 120 specifications, it features a 0.1563-inch mill diameter, four flutes with a right-hand cutting direction, and a 40-degree helix angle that promotes efficient chip evacuation. A 0.01-inch corner radius reduces stress concentration at the cutting edge and extends tool life in high-feed applications. The TiCN coating adds surface hardness and lubricity, making this end mill suited for ferrous and non-ferrous materials in demanding machining environments. Installed by machinists and tooling technicians in CNC milling operations.

This end mill is intended for use in CNC machining centers and manual milling machines where a stub-length, small-diameter tool is required. The 3/8-inch length of cut and 2-inch overall length make it well suited for shallow-to-moderate depth milling passes in tight workpiece geometries. The Weldon flat shank provides a secure, positive drive in standard end mill holders. Center-cutting capability allows direct plunge entry into the workpiece without pre-drilling.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• TiCN coating increases surface hardness and reduces friction during cutting
• 4-flute, right-hand cut with 40-degree helix angle for efficient chip evacuation
• 0.01-inch corner radius reduces edge chipping and extends tool life
• Center-cutting design allows direct plunge milling without pre-drilling
• Weldon flat shank ensures positive tool retention in standard holders

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC milling operations requiring a stub-length, 3/16-inch shank, 0.1563-inch diameter end mill with a Weldon flat drive.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat securely against the set screw in the end mill holder and verify runout with a dial indicator before beginning a cut. Do not exceed the rated depth of cut for the selected tool diameter and material combination.
