Seco 17016466 Square End Mill 1.5in 6 Flute Cobalt Ticn

Product Description

The SECO 17016466 is a single-end square end mill from the SPC408 series, ground from M42 cobalt high-speed steel and finished with a TiCN coating. It carries a 1.5-inch cutting diameter with six spiral flutes and an 8-inch length of cut, making it a capable tool for extended-reach milling operations in demanding materials. The right-hand cut and right-hand flute configuration suits standard CNC and manual milling setups. The TiCN finish increases surface hardness and wear resistance compared to uncoated cobalt tooling, helping extend tool life in abrasive and interrupted-cut applications. This end mill is installed and used by machinists and tool-and-die professionals working in production and job-shop environments.

The 17016466 is suited for milling steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys, covering primary material codes P, M, K, N, and S. The 1.25-inch shank diameter and 10.5-inch overall length allow this tool to reach deep pockets and tall workpiece features while maintaining rigidity. The centercutting geometry permits plunge milling in addition to peripheral and slot milling. The 30-degree helix angle promotes efficient chip evacuation across these material types. This tool fits applications where a standard-length end mill lacks the reach required.

Key Features

• M42 cobalt construction provides toughness and heat resistance in difficult-to-machine alloys
• TiCN coating increases wear resistance and reduces friction on the cutting edge
• Six spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge entry without a pre-drilled pilot hole
• 8-inch length of cut accommodates deep pocket and tall workpiece operations
• Right-hand cut and right-hand flute for standard spindle direction compatibility

Compatibility

Designed as an OEM-style replacement or direct-specification tooling choice for standard milling chucks, collet holders, and hydraulic toolholders accepting a 1.25-inch shank diameter. Compatible with primary workpiece materials including steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys per SPC408 series specifications.

Installation Notes

A licensed machinist or qualified toolroom technician should mount this end mill in a properly sized collet or end-mill holder and verify runout before cutting. Confirm the holder bore accepts a 1.25-inch shank and torque the retention mechanism to machine-tool manufacturer specifications. Inspect the cutting edges for chips or damage before each use. Always set spindle speed and feed rate per the tool manufacturer recommendations for the specific workpiece material and depth of cut.
