Seco 17015181 Roughing End Mill 5/8 Inch Cobalt Ticn

Product Description

The SECO 17015181 is a single-end cobalt roughing end mill designed for aggressive material removal in metalworking and machining operations. Built from M42 cobalt high-speed steel and coated with TiCN for extended tool life, this end mill features a 5/8 inch diameter with four spiral flutes and a right-hand cutting direction. The short-length geometry keeps deflection low during heavy-duty roughing passes. With a 30-degree maximum helix angle and a 1.25 inch length of cut, it delivers controlled chip evacuation without sacrificing material removal rate. Machinists and tool-and-die professionals rely on this style of roughing end mill for hogging stock in steel, stainless, and high-temperature alloys.

This end mill is suited for use on manual mills and CNC machining centers where aggressive roughing of ferrous and difficult-to-machine materials is required. The TiCN coating reduces friction and heat buildup at the cutting edge, extending tool life in interrupted cuts and continuous slotting. The 5/8 inch shank diameter matches the cutter diameter, making it straightforward to hold in standard end mill holders and collet chucks. It is a short-series tool, making it a practical choice for setups where rigidity and chatter control are priorities over reach.

Key Features

• M42 cobalt HSS construction for strength in high-heat cutting applications
• TiCN coating reduces wear and extends cutting edge life
• 4 spiral flutes with right-hand cut and right-hand flute direction
• 30-degree maximum helix angle for efficient chip evacuation
• Short-series length type for improved rigidity and reduced deflection
• Single-end design; not center-cutting

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard 5/8 inch end mill holders, collet chucks, and milling arbors used on vertical and horizontal milling machines.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder and torque the retention screw or collet nut per the holder manufacturer's specification. Verify runout with a dial indicator before beginning a roughing pass, and confirm feed and speed parameters are appropriate for the workpiece material and machine rigidity.
