Seco 17016437 Square End Mill 3/4in 6 Flute Cobalt Ticn

Product Description

The SECO 17016437 is a single-end square end mill designed for material removal in demanding machining operations. Manufactured from M42 cobalt high-speed steel and finished with a TiCN coating, it delivers wear resistance and heat tolerance well beyond standard HSS tooling. The cutter measures 0.75 inches in diameter with a 4-inch length of cut and a 6.25-inch overall length. Six spiral flutes with a 30-degree helix angle promote chip evacuation and surface finish quality. This tool is installed and used by machinists, tool-and-die makers, and CNC operators working in job shop and production environments.

The 17016437 is suited for milling steel, stainless steel, cast iron, aluminum and non-ferrous materials, and high-temperature alloys. Its TiCN coating extends tool life when cutting abrasive or work-hardening materials. The 0.75-inch shank diameter matches standard collet and end mill holder sizes common in vertical machining centers and manual knee mills. The regular-length classification makes it appropriate for general-purpose slotting, profiling, and peripheral milling where extended reach is not required. Centercutting capability allows plunge entry without a pre-drilled pilot hole.

Key Features

• M42 cobalt substrate for elevated hot hardness compared to standard M2 HSS
• TiCN coating reduces friction and extends tool life on ferrous and non-ferrous workpieces
• 6 spiral flutes with 30-degree right-hand helix for efficient chip evacuation
• Centercutting geometry allows direct plunge milling
• Right-hand cutting direction compatible with standard spindle rotation
• Mill diameter tolerance of +0.0000 to -0.0030 inches for controlled fit in tight-tolerance applications

Compatibility

Designed for use in standard 3/4-inch collets and end mill holders on vertical machining centers, CNC mills, and manual knee mills. Compatible workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys per SECO Series SPC408 application guidelines.

Installation Notes

A licensed machinist or qualified CNC operator should mount and set this tool. Secure the shank fully within the collet or end mill holder to the recommended engagement depth before tightening. Verify runout against the stated TIR maximum of 0.0010 inches after tool installation. Always confirm spindle speed and feed rate against material and depth-of-cut recommendations before beginning the cut.
