Seco 02942316 Corner Radius End Mill Head 3/16 in 4 Flute

Product Description

The SECO 02942316 is a corner radius end mill head designed for precision milling operations in metal and hard-material applications. Built from micrograin solid carbide and finished with an AlTiN coating, this single-end tool delivers extended tool life under high-speed and high-temperature cutting conditions. Part of the MZN410R series, it features a 3/16 inch (0.1875 inch) mill diameter, four spiral flutes with right-hand cutting direction, and a 10-degree helix angle. The extended-reach design and cylindrical shank make it suitable for accessing deep or restricted areas in a workpiece. Machinists and tool-and-die technicians are the primary users of this head.

This end mill head is used in short-reach, high-precision milling setups on CNC machining centers and manual mills. The 1/4 inch shank diameter fits standard toolholders commonly found in job shops, production facilities, and toolrooms. The 0.0500 inch length of cut and 15/16 inch reach length (0.9370 inch) suit finishing passes and profiling work on tight-tolerance parts. The non-centercutting geometry means it is intended for peripheral and side milling rather than plunge cuts. The AlTiN coating performs well in ferrous materials including alloy steels, hardened steels, and cast iron.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature oxidation resistance in ferrous and hard-material cutting
• 4-flute spiral geometry with right-hand cutting and flute direction
• 10-degree helix angle suited for finishing and profile milling
• Extended reach with 0.9370 inch reach length and 0.1720 inch neck diameter
• Cylindrical 1/4 inch shank fits standard toolholder collets

Compatibility

Designed as an OEM-style replacement and standard stocking tool for use with 1/4 inch cylindrical shank toolholders in CNC and manual milling applications. No specific machine model compatibility was provided in the product data.

Installation Notes

This end mill head is installed by machinists using a compatible collet or toolholder rated for a 1/4 inch cylindrical shank. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm runout with a dial indicator after seating the head to ensure concentricity. Do not use this non-centercutting tool for plunge entry cuts.
