Seco 17003582 Square End Mill 1/8 Inch 5 Flute Solid Carbide

Product Description

The SECO 17003582 is a solid carbide square end mill designed for high-performance milling in demanding metalworking applications. This single-end tool features a 1/8 inch diameter, a 1/2 inch length of cut, and a 1-1/2 inch overall length, making it suited for precision work in confined spaces and detailed profiling operations. The 5-flute geometry and 45-degree helix angle promote efficient chip evacuation and smooth surface finishes. An AlTiN coating provides thermal and wear resistance, extending tool life when cutting ferrous and difficult-to-machine materials. Licensed machinists and CNC operators working in tool and die, aerospace, and precision machining shops are the primary users of this tool.

This end mill is engineered for milling steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous materials, and hardened materials. The centercutting design allows plunge entry, giving the operator flexibility for slot milling, pocket milling, and contouring operations in a single setup. The straight shank fits standard collet chucks and end mill holders used in vertical machining centers and CNC mills. It belongs to the SECO S545 series, a long-length configuration intended for applications requiring additional reach without sacrificing rigidity at this diameter.

Key Features

• 5-flute spiral design with 45-degree helix angle for efficient chip flow and improved surface finish
• AlTiN coating delivers high hardness and oxidation resistance for extended tool life in ferrous and hardened materials
• Centercutting geometry enables direct plunge entry for slot and pocket milling
• Micrograin solid carbide construction provides rigidity and edge retention at small diameters
• Right-hand cut and right-hand flute configuration for standard CNC spindle operation
• Long-length series S545 design provides additional reach for deep-feature milling at 1/8 inch diameter

Compatibility

Designed as a replacement or standard-use solid carbide square end mill for CNC machining centers and manual mills equipped with collet chucks or end mill holders accepting a 1/8 inch straight shank. Primary workpiece material codes P, M, K, S, N, and H indicate suitability for steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle fully stopped before tool changes. Ensure the collet or tool holder is clean and free of debris before seating the shank to maintain runout within specification. Verify TIR does not exceed 0.0005 inches after installation using a dial test indicator. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting feeds, speeds, and depth of cut for the workpiece material.
