Seco 17011626 Square End Mill 5/32 in 2 Flute Cobalt

Product Description

The SECO 17011626 is a single-end cobalt square end mill designed for material removal in demanding machining applications. Built from M42 cobalt high-speed steel, this tool delivers heat and wear resistance that outperforms standard HSS in harder workpiece materials. The 2-flute, right-hand spiral configuration provides efficient chip evacuation and clean edge geometry on milled slots, pockets, and profiles. The bright/uncoated finish keeps the cutting edge sharp and allows for easy wear inspection during service. Machinists and toolroom technicians rely on this style of end mill for precision work on ferrous and high-temperature alloy materials.

This end mill is suited for milling operations on steel, stainless steel, cast iron, and high-temperature alloys in both job shop and production environments. The 5/32 inch diameter and 7/16 inch length of cut make it appropriate for small-slot and fine-detail work where a larger tool cannot reach. The 3/8 inch shank seats in standard collet chucks and tool holders common to knee mills, CNC machining centers, and manual milling machines. It is a single-end tool from the SP205 series with a 30-degree helix angle optimized for right-hand cutting.

Key Features

• M42 cobalt material grade for elevated heat resistance and extended tool life on hard materials
• 2-flute right-hand spiral geometry promotes chip clearing in slotting and pocketing cuts
• 30-degree helix angle balances cutting efficiency and edge strength on ferrous and high-temp alloys
• Bright/uncoated finish provides visual wear indication and suits applications where coatings are not required
• Center-cutting design allows plunge entry without a pre-drilled pilot hole
• Single-end construction with a 3/8 inch shank for compatibility with standard collet systems

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for standard 3/8 inch collet chucks and tool holders on vertical and CNC milling machines. Intended for use on steel, stainless steel, cast iron, and high-temperature alloy workpieces per the SP205 series application guidelines.

Installation Notes

This end mill is installed by qualified machinists or toolroom technicians familiar with rotating cutting tools and milling machine operation. Power down and lock out the machine spindle before seating or removing the tool from the collet or tool holder. Ensure the shank is fully seated and the collet is torqued to the machine manufacturer's specification before operating. Do not exceed the recommended depth of cut or feed rate for the workpiece material and spindle speed combination in use.
