Seco 17015180 Roughing End Mill 5/8 in 4 Flute Cobalt

Product Description

The SECO 17015180 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 for improved wear resistance and heat tolerance, this tool handles tough ferrous and non-ferrous workpieces. The 5/8 inch diameter, 4-flute configuration with a 30-degree maximum helix angle and right-hand cut delivers efficient chip evacuation and stable cutting action. At a stub length overall of 2-7/8 inches with a 3/4 inch length of cut, this end mill is suited for short-reach roughing passes where rigidity is a priority. Machinists and tool-and-die professionals are the primary installers of this tool.

This end mill is intended for use in CNC machining centers, knee mills, and manual milling machines where roughing operations on steel, stainless, and similar alloys are required. The stub length profile reduces deflection during heavy cuts, making it a practical choice for slotting, profiling, and peripheral milling in production and job-shop environments. The TiCN coating extends tool life in high-friction cutting conditions compared to uncoated cobalt tooling. Non-centercutting geometry means this tool is not suited for plunge cuts.

Key Features

• M42 cobalt construction for elevated hardness and heat resistance at cutting temperatures
• TiCN coating reduces friction and extends tool life in ferrous milling
• 4 flutes with right-hand spiral and right-hand cut for standard CNC and manual mill spindles
• 30-degree maximum helix angle supports efficient chip flow during roughing passes
• Stub length (2-7/8 inches OAL) maximizes rigidity and minimizes deflection
• Non-centercutting — designed for peripheral and slot milling, not plunge entry

Compatibility

Designed as an OEM-style replacement or direct fitment for milling applications requiring a 5/8 inch shank, 5/8 inch diameter, single-end roughing end mill in the SECO REM710 series.

Installation Notes

Installation is performed by machinists using an appropriate collet or end mill holder matching the 5/8 inch shank diameter. Ensure the spindle and tool holder are clean and free of debris before seating the tool. Follow machine manufacturer runout specifications and confirm holding torque per the tool holder manufacturer guidelines. This tool is not designed for plunge cutting — use a suitable centercutting end mill or drill for initial entry.
