Seco 17016584 Roughing End Mill 0.5 in 4 Flute Cobalt

Product Description

The SECO 17016584 is a single-end roughing end mill designed for high-material-removal-rate milling operations in ferrous and hard materials. Built from M42 cobalt high-speed steel with a TiCN coating, it delivers elevated heat and wear resistance compared to standard HSS tooling. The 0.5-inch diameter, 4-flute geometry with a 30-degree helix angle and spiral flute pattern promotes efficient chip evacuation while maintaining rigidity during aggressive cuts. It is a center-cutting tool, allowing plunge entry. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual knee mills for roughing passes on steel, stainless, and alloy workpieces.

The 17016584 is suited for short-reach roughing applications in job shops, production machining environments, and maintenance machining operations. With a 1-inch length of cut and 3-inch overall length, it fits standard 0.5-inch collets and end mill holders. The right-hand cutting and right-hand flute direction make it compatible with conventional spindle rotation. No coolant-through capability means it is intended for flood coolant or air-blast cooling delivered externally. This tool is part of the SECO REC700 series, optimized for roughing performance in short-length configurations.

Key Features

• M42 cobalt construction provides superior hot hardness for cutting steel and alloy materials
• TiCN coating increases surface hardness and reduces tool wear during extended roughing passes
• 4-flute spiral geometry with 30-degree helix angle for balanced chip load and rigidity
• Center-cutting design allows direct plunge entry without pre-drilling
• Short-length (REC700 series) configuration minimizes deflection in shallow-reach applications
• Right-hand cut and right-hand flute direction for standard spindle compatibility

Compatibility

Designed for use in standard 0.5-inch end mill holders, collet chucks, and milling machine spindles accepting a 0.5-inch shank diameter. Part of the SECO REC700 series for short roughing end mill applications.

Installation Notes

Installation is performed by qualified machinists following standard tool-holding procedures. Power down and lock out the spindle before inserting or changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque the set screw or collet nut per the tool holder manufacturer specification. Verify runout with a dial indicator before commencing a roughing pass, and confirm the machine spindle direction matches the right-hand cutting orientation of this tool.
