Seco 17016576 Roughing End Mill 3/16 in 4 Flute Cobalt

Product Description

The SECO 17016576 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiCN coating, it handles tough ferrous and non-ferrous materials while maintaining edge integrity under heat. The 3/16 inch cutting diameter pairs with a 1/2 inch length of cut and a 3/8 inch shank, making it well suited for tight-clearance slotting and profiling work. With 4 spiral flutes and a 30-degree helix angle, the right-hand cutting geometry promotes chip evacuation and reduces chatter. This tool is installed by machinists and tool-and-die professionals in production and job-shop environments.

This roughing end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills. The centercutting design allows plunge entry, expanding its versatility for ramping and pocket milling applications. The TiCN coating reduces friction and extends tool life when cutting alloy steels, stainless steel, cast iron, and similar hard materials. The REC700 series designation indicates it is part of a purpose-built roughing geometry line intended for high-feed roughing passes where surface finish is secondary to material removal rate.

Key Features

• M42 cobalt HSS construction for elevated red-hardness and heat resistance
• TiCN coating reduces friction and extends cutting life on hard materials
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard spindle operation
• 3/8 inch shank diameter with tight shank tolerance for secure collet or end mill holder grip

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling applications requiring a 3/8 inch shank roughing end mill with a 3/16 inch cutting diameter.

Installation Notes

This end mill is installed by machinists using a collet chuck or end mill holder rated for the 3/8 inch shank diameter. Verify runout with a dial indicator before high-feed passes. Inspect shank and collet seating surfaces for chips or burrs before tightening. Follow machine tool manufacturer torque recommendations for drawbar and holder fasteners.
