Seco 17016418 Square End Mill 0.5in 4 Flute Cobalt Ticn

Product Description

The SECO 17016418 is a single-end square end mill designed for precision material removal in ferrous and non-ferrous machining applications. Built from M42 cobalt high-speed steel and coated with titanium carbonitride (TiCN), this tool delivers extended wear resistance and heat tolerance under demanding cutting conditions. It features a 0.5-inch mill diameter, a 1.25-inch length of cut, and a 3.25-inch overall length. The 30-degree spiral flute geometry and four-flute configuration promote efficient chip evacuation while maintaining surface finish quality. Machinists and tool-and-die professionals working in job shops or production environments will find this end mill well-suited to a broad range of milling operations.

This end mill is designed for use on CNC machining centers and manual knee mills where right-hand cutting and right-hand flute direction are required. Its centercutting capability allows direct plunge entry without a pre-drilled pilot hole. Primary workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and high-temperature alloys. The 0.5-inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style tool holders commonly found in production and toolroom setups. This tool belongs to the SECO SPC408 series.

Key Features

• TiCN coating extends tool life on steel, stainless, and high-temp alloys
• Centercutting design allows direct plunge milling without a pilot hole
• 30-degree helix angle with spiral flutes for efficient chip evacuation
• Right-hand cut and right-hand flute for standard CNC and manual mill compatibility
• Single-end configuration for straightforward toolholder setup

Compatibility

Designed as a direct-fit replacement or standard toolroom end mill for machining steel, stainless steel, cast iron, aluminum and non-ferrous materials, and high-temperature alloys. Compatible with any 0.5-inch bore end mill holder, ER collet, or Weldon-style holder. Part of the SECO SPC408 series.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 0.5-inch shank fully into the holder and torque the retention mechanism per the holder manufacturer's specification. Verify runout does not exceed the maximum TIR of 0.001 inches before cutting.
