Seco 17013508 Roughing End Mill 1-1/8 in 6 Flute Cobalt

Product Description

The SECO 17013508 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and finished with a TiCN coating, this tool delivers heat resistance and wear performance suited to ferrous and non-ferrous machining. The cutter measures 1.125 inches in diameter with a 1-inch shank and a 2-inch length of cut, giving machinists the reach and rigidity needed for standard roughing passes. Six right-hand spiral flutes at a 30-degree maximum helix angle break chips efficiently and reduce cutting load per edge. At 4.5 inches overall length, it fits standard milling machine spindles and CNC machining centers running right-hand cutting direction.

This end mill is suited for roughing applications in job shops, tool rooms, and production machining environments. The REM710 series geometry is built around interrupted-cut chip breaking, reducing radial forces and heat buildup during heavy stock removal. It is a non-centercutting, non-coolant-through tool, making it appropriate for conventional side milling and profiling where through-spindle coolant is not required. Machinists working on steel, stainless, and tough alloys will find the M42 substrate and TiCN coating a practical combination for extended tool life without regrinding frequency.

Key Features

• M42 cobalt substrate for elevated red hardness and toughness in demanding cuts
• TiCN coating reduces friction and increases surface hardness for extended tool life
• 6 right-hand spiral flutes at 30-degree helix for efficient chip evacuation
• 1.125-inch mill diameter with 2-inch length of cut suits standard roughing depths
• 1-inch shank diameter with tight tolerance (-0.0001 to -0.0005 inches) for secure holder fit
• Single-end construction; right-hand cutting direction; regular length series

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill compatible with standard end mill holders and collet chucks accepting a 1-inch shank diameter in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or tool crib technician. Secure the 1-inch shank in a properly sized end mill holder or collet chuck and confirm runout before cutting. Power down and lock out the spindle before tooling changes. Do not use this tool as a plunge-cutting drill — it is non-centercutting and should enter the workpiece radially or via a ramping strategy.
