Seco 17003611 Square End Mill 1/2 in 5 Flute Carbide Altin

Product Description

The SECO 17003611 is a single-end, solid micrograin carbide square end mill designed for high-performance milling in demanding shop environments. It features a 0.5 inch mill diameter, a 0.625 inch length of cut, and a 0.5 inch straight shank with an overall length of 2.5 inches. The tool carries an AlTiN coating and a 45-degree spiral flute helix with 5 flutes, delivering efficient chip evacuation and heat resistance during aggressive cuts. Machinists and tool-and-die professionals use this end mill for slotting, profiling, and shoulder milling across a wide range of workpiece materials.

This stub-length end mill is suited for CNC machining centers and manual mills where rigidity and reduced deflection are priorities. Its right-hand cut and right-hand spiral flute geometry, combined with centercutting capability, allow both plunge and side-milling operations. The AlTiN coating provides oxidation resistance at elevated cutting temperatures, making it appropriate for dry or minimum-quantity-lubrication machining strategies in production and job-shop settings.

Key Features

• 5-flute design increases feed rates and improves surface finish compared to standard 4-flute geometry
• AlTiN coating resists heat and wear during high-speed cutting in ferrous and hard materials
• 45-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge entry without pre-drilling
• Micrograin solid carbide substrate provides rigidity and edge retention
• Stub length construction maximizes tool stiffness and minimizes runout in tight setups

Compatibility

Designed for use on CNC machining centers and manual mills accepting a 0.5 inch straight shank. Rated for milling steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous materials, and hardened materials per ISO material codes P, M, K, S, N, and H. Part of the SECO Series S545.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the shank in a collet or end-mill holder rated for the shank diameter tolerance of -0.0001 to -0.0004 inches to maintain runout within the specified 0.0005 inch TIR maximum. Verify spindle and tool holder cleanliness before seating the tool. Follow machine manufacturer and shop safety protocols for tooling changes, including spindle lock-out procedures.
