Seco 17014236 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The SECO 17014236 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 1-inch mill diameter pairs with a 4-inch length of cut and a 6.5-inch overall length, making it well-suited for deep-pocket roughing passes. With 5 right-hand spiral flutes and a 30-degree maximum helix angle, it channels chips efficiently while maintaining cutting stability. This tool is installed by machinists and tool-and-die professionals in production and job-shop environments.

This end mill is used in vertical and horizontal milling machines for roughing operations on steel, stainless, and similar hard alloys. The bright uncoated finish is standard for M42 cobalt tooling and suits applications where coatings are not required or where regrinding is anticipated. The 1-inch shank diameter matches the 1-inch mill diameter for direct-fit collet or end mill holder mounting. It is a single-end tool, meaning the cutting geometry is on one end only. Typical applications include slotting, peripheral milling, and step milling in both manual and CNC setups.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance in tough materials
• 5 right-hand spiral flutes with 30-degree maximum helix angle for efficient chip evacuation
• 4-inch length of cut supports deep-pocket and deep-slot roughing passes
• Bright uncoated finish suitable for applications requiring regrinding or where coatings are unnecessary
• Right-hand cutting direction with regular-length flute geometry for standard milling setups
• Non-center-cutting design — requires a pre-drilled entry point or ramping where applicable

Compatibility

Designed as an OEM-style roughing end mill in the SECO REM710 series, compatible with standard 1-inch collet chucks and end mill holders used in vertical and horizontal milling machines.

Installation Notes

Installation is performed by machinists using standard end mill holders or collet chucks rated for 1-inch shank tooling. The machine spindle must be fully stopped and locked out before mounting or removing the tool. Because this is a non-center-cutting end mill, do not plunge directly into solid material — use a pre-drilled hole or a programmed ramp entry. Confirm shank runout with a dial indicator before beginning a roughing pass to avoid premature tool wear.
