Seco 17013509 Roughing End Mill 1-1/4 in 6 Flute Cobalt

Product Description

The SECO 17013509 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel and coated with TiCN, this tool handles demanding cuts in tough alloys and hardened materials where standard HSS tooling falls short. The 1.25-inch diameter cutter features 6 spiral flutes with a right-hand cutting and flute direction, a 30-degree maximum helix angle, and a 2-inch length of cut. At 4.5 inches overall length, it fits standard milling machine and machining center setups. This tool is suited for machinists and tool-and-die professionals working in job shops or production environments.

The 17013509 is intended for roughing passes on ferrous and non-ferrous metals, including alloy steels and stainless grades where cobalt tooling is preferred over carbide in interrupted-cut scenarios. The 6-flute configuration increases chip load per tooth at moderate feeds, making it a practical choice for hogging material before a finishing pass. The 1.25-inch shank diameter matches the cutter diameter for direct collet or end mill holder mounting on vertical mills, HMCs, and VMCs running right-hand spindles.

Key Features

• M42 cobalt construction for heat resistance and edge retention in tough alloys
• TiCN coating reduces friction and extends tool life in abrasive materials
• 6 right-hand spiral flutes with 30-degree maximum helix angle for efficient chip evacuation
• 2-inch length of cut supports full-depth roughing passes without excessive overhang
• Single-end design with 1.25-inch shank diameter for direct holder mounting
• Regular length series (REM710) for rigid setups with minimal deflection

Compatibility

Designed as a direct-fit roughing end mill for milling machines and machining centers accepting a 1.25-inch shank diameter end mill holder or collet chuck with right-hand spindle rotation.

Installation Notes

Installation requires a milling machine or machining center with a properly sized end mill holder or collet rated for 1.25-inch shanks. Ensure the spindle and holder are clean and free of debris before seating the tool. Set machine spindle direction to right-hand rotation before engaging the cut. This is not a centercutting tool and should not be plunged axially into solid material.
