Seco 17016365 Square End Mill 5/32 in 2 Flute Cobalt Ticn

Product Description

The SECO 17016365 is a single-end, square-profile cobalt end mill designed for metal removal in ferrous and high-temperature alloy applications. Built from M42 cobalt high-speed steel and coated with titanium carbonitride (TiCN), this tool offers improved hardness and wear resistance compared to standard HSS tooling. The cutter features a 5/32-inch diameter, a 7/16-inch length of cut, and a 30-degree spiral helix with two right-hand flutes. The centercutting geometry allows direct plunging as well as conventional milling operations. It is installed in CNC machining centers, knee mills, and manual milling machines by machinists and tooling technicians working in job shops and production environments.

This end mill is intended for use on steel, stainless steel, cast iron, and high-temperature alloys, covering ISO material groups P, M, K, and S. With a 3/8-inch shank diameter and a 2-5/16-inch overall length, it fits standard collet chucks and end mill holders commonly found in light-duty to medium-duty milling setups. The SP205 series is optimized for general-purpose profiling, slotting, and peripheral milling where a smaller diameter cutter is required for detail work or tight geometries.

Key Features

• M42 cobalt construction for elevated red hardness and tool life in ferrous materials
• TiCN coating improves surface hardness and reduces built-up edge on steel and stainless
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 30-degree right-hand spiral flute promotes efficient chip evacuation during slotting
• 3/8-inch shank fits standard collet and end mill holder tooling
• Single-end construction — part of the SP205 fractional-inch series

Compatibility

Designed for use in standard 3/8-inch collet chucks and end mill holders on CNC machining centers, vertical knee mills, and manual milling machines capable of accepting fractional-inch shank tooling.

Installation Notes

Installation is performed by a machinist or tooling technician. The tool should be seated fully in a clean, undamaged collet or end mill holder and secured to the recommended torque for the holder type. Inspect the shank and cutting edges for damage before each use. Spindle runout should be verified against the specified TIR maximum before initiating a cut to avoid premature tool wear or workpiece dimensional error.
