Promax 119-01216 Corner Radius End Mill 3/16 in Carbide

Product Description

The PROMAX 119-01216 is a solid carbide corner radius end mill designed for roughing and finishing operations in a single tool. Built from micrograin carbide with a ZrN (zirconium nitride) coating, it runs a 3/16-inch diameter with a 0.010-inch corner radius and a 40-degree helix angle. The three-flute, right-hand cutting geometry balances chip evacuation with surface finish quality. This tool is intended for machinists and toolroom technicians working in job shops, production machining, or maintenance environments requiring precise milling in ferrous and non-ferrous materials.

The 119-01216 fits vertical and horizontal milling machines, CNC machining centers, and manual knee mills accepting a 3/16-inch straight cylindrical shank. Its regular-length profile with a 5/8-inch length of cut and 2-inch overall length suits shoulder milling, profiling, and light slotting where a corner radius is specified to reduce stress concentration at part corners. It is centercutting, allowing plunge entry. No extended reach is incorporated, keeping the tool rigid for close-tolerance work.

Key Features

• Solid micrograin carbide construction for improved wear resistance and edge retention
• ZrN coating reduces friction and extends tool life in aluminum, brass, and similar non-ferrous materials
• 0.010-inch corner radius reduces corner chipping on the workpiece and on the cutting edge
• 40-degree helix angle promotes smooth cutting action and efficient chip flow
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand flute direction with right-hand cutting for standard spindle rotation
• Single-end configuration; Series 119 straight cylindrical shank with tight diameter tolerance

Compatibility

Designed as a direct-fit replacement or standard selection for any milling machine or machining center that accepts a 3/16-inch straight cylindrical shank, including ER collet chucks and end mill holders sized for 3/16-inch tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank in a properly sized collet or end mill holder, ensuring the shank is fully seated and the holding device is tightened to the machine tool manufacturer's specification. Inspect the collet or holder for runout before beginning a cut, as excessive runout accelerates edge wear on small-diameter carbide tools. Always power down and lock out the spindle before changing tooling.
