Seco 17013554 Roughing End Mill 3/4 in 3 Flute Cobalt

Product Description

The SECO 17013554 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a TiCN coating, it delivers elevated heat and wear resistance compared to standard HSS tooling. The cutter measures 0.75 inches in diameter with a 1.625-inch length of cut and a 3.875-inch overall length. Three flutes with a high-helix spiral geometry at 36 degrees promote efficient chip evacuation and reduce cutting forces. This tool is center-cutting and right-hand cutting, making it suitable for plunge and slot milling operations. Licensed machinists and tool-and-die professionals are the primary installers.

This roughing end mill is suited for roughing passes on ferrous and non-ferrous metals in both manual and CNC milling setups. The cobalt M42 substrate and TiCN coating make it a practical choice for harder workpiece materials where standard HSS tools show premature wear. The 3/4-inch shank diameter matches common ER and side-lock collet systems found on vertical machining centers and knee mills. It is intended for single-end use and carries a regular-length classification for general-purpose roughing work.

Key Features

• M42 cobalt steel construction for improved hardness and heat resistance over standard HSS
• TiCN coating reduces friction and extends tool life on harder materials
• 3-flute, high-helix spiral design at 36 degrees promotes efficient chip evacuation
• Center-cutting geometry allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute direction for standard spindle operation
• Series RHC752 single-end configuration with regular length classification

Compatibility

Designed as an OEM-style replacement roughing end mill for use in standard 3/4-inch collet or side-lock tool holders on vertical machining centers, knee mills, and similar milling equipment.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the minimum insertion depth recommended by the toolholder manufacturer. Verify runout with a dial indicator before beginning cuts to avoid premature tool wear or workpiece damage.
