Promax 119-02814 Corner Radius End Mill 7/16 in 3 Flute

Product Description

The PROMAX 119-02814 is a solid carbide corner radius end mill designed for roughing and finishing operations in a single tool. The 7/16 inch diameter cutter features a 0.02 inch corner radius on a three-flute, right-hand cutting geometry with a 40-degree helix angle. The AlTiN coating provides heat resistance and extended tool life in ferrous and high-temperature alloys. Micrograin carbide substrate adds toughness and edge retention under heavy chip loads. This is a single-end, center-cutting tool with a straight cylindrical shank, suited for CNC machining centers and manual mills running demanding materials.

This end mill is suited for milling operations that require both material removal and a finished surface in one pass. The corner radius geometry reduces edge chipping and improves surface finish at part corners compared to a square end mill. Typical applications include profiling, contouring, and pocket milling in steel, stainless, titanium, and similar hard materials. The 1 inch length of cut and 2-3/4 inch overall length make it a compact, rigid tool appropriate for moderate-depth cuts in a production or job-shop environment.

Key Features

• 7/16 inch mill diameter with 0.02 inch corner radius for reduced stress at part corners
• 3-flute right-hand cutting geometry with 40-degree helix for efficient chip evacuation
• AlTiN coating for elevated heat resistance and extended tool life in hard materials
• Micrograin solid carbide substrate for superior edge retention and rigidity
• Center-cutting design allows direct plunge entry
• Straight cylindrical shank with tight diameter tolerance for secure toolholder fit

Compatibility

Designed as an OEM-style solid carbide corner radius end mill in the PROMAX Series 119 lineup, compatible with standard 7/16 inch ER collets, hydraulic chucks, and shrink-fit holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, de-energized state. Ensure the toolholder bore and shank are clean and free of chips before seating the end mill. Confirm runout with a dial indicator after clamping to verify proper seating. Follow the machine tool manufacturer torque specifications for the toolholder style in use.
