Promax 102-02416 Corner Radius End Mill 3/8in 3 Flute Carbide

Product Description

The PROMAX 102-02416 is a solid carbide corner radius end mill designed for precision milling operations where a controlled edge radius is required to reduce stress concentrations and extend tool life. Built to Series 102 specifications, this 3-flute cutter features a 3/8 inch cutting diameter, a 7/8 inch length of cut, and a corner radius ranging from 0.055 to 0.065 inches. A ZrN (zirconium nitride) coating reduces friction and improves wear resistance. The high-helix, right-hand cutting geometry promotes efficient chip evacuation. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual mills for profiling, slotting, and finishing passes.

This end mill is suited for milling operations on ferrous and non-ferrous materials where a fine corner radius improves part strength and surface finish. The centercutting design allows plunge entry directly into the workpiece. Its coarse pitch and high helix angle make it a solid choice for roughing and semi-finishing passes in a shop or production environment. The regular length profile fits standard toolholders without extended-reach considerations.

Key Features

• 3/8 inch cutting diameter with 7/8 inch length of cut for standard-depth milling
• Corner radius of 0.055 to 0.065 inches reduces stress risers at part corners
• 3 flutes with high-helix, right-hand geometry for efficient chip removal
• ZrN coating improves surface hardness and wear resistance
• Centercutting design enables direct plunge milling
• Solid carbide construction provides rigidity and dimensional stability

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide corner radius end mill for use in standard 3/8 inch collet or end mill toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 3/8 inch shank fully in the toolholder and torque the retention system per the toolholder manufacturer's specifications. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
