Seco 17003586 Square End Mill 3/16 in 5 Flute Carbide

Product Description

The SECO 17003586 is a single-end square end mill designed for precision material removal in demanding machining environments. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers heat resistance and wear life in high-speed applications. The tool measures 0.1875 inches in diameter with a 9/16-inch length of cut and a 2-inch overall length. Its 5-flute geometry and 45-degree helix angle support aggressive feed rates while maintaining a quality surface finish. Centercutting capability allows plunge entry. This end mill belongs to the SECO Series S545 product family.

This end mill is suited for milling operations on steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous materials, and hardened materials. It is used in CNC machining centers and manual mills for slotting, profiling, and peripheral milling tasks. The straight shank and right-hand cut with right-hand flute orientation make it a standard fit for conventional toolholding systems. It is appropriate for job shops, production floors, and precision component manufacturing where tight tolerances are required.

Key Features

• 5-flute spiral design with 45-degree helix angle for efficient chip evacuation and surface finish
• AlTiN coating provides oxidation resistance and thermal hardness at elevated cutting temperatures
• Micrograin solid carbide substrate delivers rigidity and edge retention in difficult-to-machine materials
• Centercutting geometry enables direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute orientation for use in standard CNC and manual mill setups
• Tight tolerances: mill diameter -0.0000/-0.0020 inches, shank diameter -0.0001/-0.0004 inches, TIR max 0.0005 inches

Compatibility

Designed as an OEM-style cutting tool for use in standard straight-shank toolholders sized for 3/16-inch shank diameter, compatible with CNC machining centers and manual mills across a range of workpiece materials including steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials.

Installation Notes

This tool is installed by machinists in CNC or manual milling machines using a collet, end mill holder, or shrink-fit toolholder rated for 3/16-inch shank diameter. Ensure the spindle is fully stopped and locked before inserting or removing the tool. Verify runout with a dial indicator prior to cutting; TIR should not exceed 0.0005 inches. Do not exceed the manufacturer-recommended cutting parameters for the workpiece material grade being machined.
