Seco 17013490 Roughing End Mill 5/16 in 4 Flute Cobalt

Product Description

The SECO 17013490 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and finished with a TiCN coating, it delivers enhanced wear resistance and heat tolerance compared to standard HSS tooling. The 5/16-inch diameter cutter features 4 right-hand spiral flutes with a 30-degree maximum helix angle, producing the interrupted chip pattern characteristic of roughing geometry. This tool is used by machinists and tooling technicians on manual mills and CNC machining centers where rapid stock removal is the priority before a finishing pass.

This roughing end mill is suited for ferrous and non-ferrous metal cutting applications in job shop, production, and maintenance machining environments. With a 1.375-inch length of cut and a 3.125-inch overall length, it fits standard 3/8-inch collets and tool holders. It is a non-centercutting design, meaning it is intended for side milling and slotting rather than plunge cutting. The regular-length profile keeps deflection low during heavy lateral passes.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• TiCN coating reduces friction and extends tool life in steel and alloy applications
• 4 right-hand spiral flutes at 30-degree helix angle for efficient chip evacuation
• Roughing geometry breaks chips into smaller segments, reducing cutting forces
• 3/8-inch shank fits standard collets and milling chucks
• Right-hand cutting direction compatible with conventional mill spindle rotation

Compatibility

Designed as a direct-fit replacement for 3/8-inch shank roughing end mill tooling in standard ER collet chucks, milling chucks, and shrink-fit holders used on vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips or debris before seating the shank. Torque the collet nut or chuck to the tool holder manufacturer's specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on roughing geometry.
