Promax 106-01224 Corner Radius End Mill 3/16in 3 Flute

Product Description

The PROMAX 106-01224 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 3/16 inch diameter with a 0.010 inch corner radius that reduces stress concentration at the tool path edge, extending tool life in hard-material cuts. The three-flute geometry balances chip evacuation with rigidity, and the 35-degree helix angle promotes smooth cutting action. An AlTiN coating provides thermal resistance at elevated cutting temperatures, making this tool well-suited for ferrous and hardened materials. Licensed machinists and CNC programmers use this tool for finish profiling, slotting, and contour work.

This end mill is used in CNC machining centers and manual knee mills for light-to-medium milling operations on steel, stainless steel, cast iron, and similar ferrous alloys where a corner break or blend radius is required on the finished part. Its centercutting capability allows plunge entry directly into the workpiece without a pre-drilled starting hole. The 3/8 inch length of cut and 2 inch overall length suit shallow-to-moderate depth pockets and profiles in production and toolroom environments.

Key Features

• Solid micrograin carbide substrate for rigidity and wear resistance in hard materials
• AlTiN coating for high-temperature performance on ferrous and hardened workpieces
• 0.010 inch corner radius reduces edge chipping and produces a blended corner on finished surfaces
• Three-flute design balances chip clearance and tool body strength
• 35-degree helix angle promotes smooth, low-vibration cutting action
• Centercutting single-end configuration allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed for use in CNC machining centers and manual mills with ER or straight-shank collet systems accepting a 3/16 inch shank diameter. Part of the PROMAX Series 106 corner radius end mill line.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank in a properly sized collet or end mill holder, ensuring full engagement depth per the holder manufacturer recommendation. Confirm spindle speed and feed rate are set per the material and coating manufacturer guidelines before cutting. Inspect the collet and holder for runout before use, as excessive runout accelerates edge wear on carbide tooling.
