Seco 17003584 Square End Mill 5/32 in 5 Flute Carbide Altin

Product Description

The SECO 17003584 is a single-end square end mill designed for precision milling in demanding metalworking applications. Built from micrograin solid carbide and coated with AlTiN for heat and wear resistance, this tool handles steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. It features 5 spiral flutes with a 45-degree helix angle, a right-hand cut, and a right-hand flute direction. The mill diameter is 5/32 inches (0.1563 inches), with a 3/16-inch straight-cylindrical shank. This tool is installed by machinists and tool-and-die professionals on CNC mills and manual milling machines.

This end mill fits standard milling operations requiring a long-reach, centercutting tool in a compact diameter. The 9/16-inch length of cut and 2-inch overall length make it suited for slotting, profiling, and finishing passes in tight geometries. Primary workpiece material categories include ISO P (steel), M (stainless steel), K (cast iron), S (high-temp alloy), N (aluminum and non-ferrous), and H (hardened materials). It carries UNSPSC code 27112803 and belongs to the SECO S545 series.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• AlTiN coating provides thermal protection and extended tool life in ferrous and hardened material cuts
• 5 spiral flutes at 45-degree helix angle for improved chip evacuation and surface finish
• Centercutting geometry allows plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindle compatibility
• Long-length classification with 9/16-inch LOC relative to 5/32-inch diameter for reach into deep features

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard straight-cylindrical shank tool holders accepting a 3/16-inch shank diameter, such as collet chucks and end mill holders used on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a qualified machinist or toolroom professional. Secure the 3/16-inch shank in a clean, properly sized collet or end mill holder, torquing the retention mechanism to the machine manufacturer's specification. Inspect the collet and holder for runout before use — the maximum TIR for this tool is 0.0005 inches. Ensure the spindle is fully stopped and the machine is in a safe state before changing or adjusting tooling.
