Seco 17002226 Square End Mill 0.5 in 3 Flute Solid Carbide

Product Description

The SECO 17002226 is a solid carbide square end mill designed for high-performance material removal in aluminum and non-ferrous metals. Built to Series AN345 specifications, it features a 0.5-inch mill diameter, a 45-degree helix angle, and a micrograin carbide substrate that supports aggressive feed rates and extended tool life. The bright uncoated finish makes it well suited for aluminum alloys where coatings can cause built-up edge. With a long-reach configuration and center-cutting capability, this end mill handles both plunge entry and profiling passes. It is a single-end tool with a straight 0.5-inch shank, right-hand cut, and right-hand spiral flute geometry.

This end mill is intended for use in CNC machining centers, vertical mills, and manual knee mills where aluminum, brass, copper, and other non-ferrous workpiece materials are processed. The 3-flute configuration balances chip clearance with rigidity, making it a practical choice for slotting, profiling, and pocketing operations in non-ferrous stock. The 3-inch reach length and 0.625-inch length of cut allow access to deeper features without excessive deflection. Machinists and toolroom professionals in production shops and job shops are the primary users.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in non-ferrous applications
• 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces in aluminum
• Center-cutting design allows direct plunge entry without a pre-drilled pilot hole
• Bright uncoated finish prevents aluminum adhesion and built-up edge
• Long-reach geometry with 3-inch reach length for access to deeper features
• Right-hand cut and right-hand flute spiral for standard CNC and manual mill spindle compatibility

Compatibility

Designed as an OEM-style cutting tool for use in standard straight-shank tool holders and collet chucks accepting a 0.5-inch shank diameter, suited for CNC and manual milling operations on aluminum and non-ferrous workpiece materials.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Use a properly sized collet or end mill holder to achieve accurate runout within the specified TIR maximum of 0.0005 inches. Verify workpiece fixturing and set appropriate speeds and feeds for the specific non-ferrous material being cut before engaging the spindle.
