Seco 17003588 Square End Mill 7/32 in 5-flute Carbide Altin

Product Description

The SECO 17003588 is a single-end square end mill designed for high-performance milling across a broad range of workpiece materials. Built from micrograin solid carbide and coated with an AlTiN finish, it delivers heat resistance and extended tool life in demanding cutting environments. The 7/32-inch (0.2188-inch) cutting diameter pairs with a 3/4-inch length of cut, a 1/4-inch straight-cylindrical shank, and a 2-1/2-inch overall length. Five spiral flutes at a 45-degree helix angle promote efficient chip evacuation and smooth surface finishes. Licensed machinists and CNC operators in job shops, production facilities, and toolrooms are the primary users of this tool.

The 17003588 is suited for milling operations on steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. Its centercutting geometry allows plunge entry, making it practical for slot milling, profiling, and pocket work without a pre-drilled start hole. The right-hand cut and right-hand flute configuration is standard for conventional CNC vertical and horizontal machining centers. No coolant-through capability is present, so external coolant or air blast is recommended for heat management in high-feed applications.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating provides high-temperature oxidation resistance, extending tool life in dry and semi-dry cutting
• Five-flute design increases chip load capacity and feed rate potential versus standard four-flute geometry
• 45-degree helix angle promotes aggressive chip evacuation and reduces cutting forces
• Centercutting geometry enables direct plunge entry for slot and pocket operations
• Straight-cylindrical 1/4-inch shank fits standard collet chucks and end mill holders without adapters

Compatibility

Part of the SECO S545 series. Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills equipped with a 1/4-inch collet or end mill holder.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention hardware to the machine manufacturer's specification. Verify runout does not exceed the rated TIR maximum of 0.0005 inches before commencing a cut.
