Seco 17014581 Roughing End Mill 3/8 in Cobalt 3 Flute

Product Description

The SECO 17014581 is a single-end cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers durability and heat resistance in demanding cutting environments. The tool features a 3/8-inch mill diameter, a 3/4-inch length of cut, and a high helix style at a 36-degree maximum helix angle. Three spiral flutes and a right-hand cutting direction make this mill well-suited for machinists removing stock quickly while maintaining edge stability. It is center cutting, allowing plunge entry, and carries a short length type for added rigidity during cuts.

This roughing end mill is intended for use in vertical and horizontal milling machines, CNC machining centers, and manual mills in shop, toolroom, and production environments. The M42 cobalt grade performs reliably on ferrous materials, stainless steels, and other alloys that generate higher cutting temperatures. Machinists and tool-and-die professionals working in light manufacturing or fabrication will find this a practical choice for roughing passes before finishing operations. The 3/8-inch shank diameter matches the mill diameter for straightforward collet or end mill holder fitment.

Key Features

• M42 cobalt steel construction for elevated heat resistance and edge retention
• 3 spiral flutes with high helix angle (36 degrees) for efficient chip evacuation
• Center cutting geometry allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute direction for standard spindle operation
• Bright, uncoated finish — no coating to mask wear or add unpredictable thickness
• Short length type increases rigidity and reduces deflection during roughing passes

Compatibility

Designed as an OEM-style single-end roughing end mill for use in standard 3/8-inch collets or end mill holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Secure the shank fully within the collet or end mill holder to the recommended engagement depth before tightening. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout with a dial indicator after installation to confirm proper seating and minimize premature edge wear.
