Seco 17010371 Roughing End Mill 7/16 in 4 Flute Cobalt

Product Description

The SECO 17010371 is a single-end cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it features a 7/16 inch (0.4375 inch) cutting diameter and four flutes configured for right-hand cutting and right-hand flute direction. The 1 inch length of cut and 3/8 inch shank diameter make it well-suited for roughing passes where chip clearance and tool rigidity are priorities. Licensed machinists and CNC operators typically reach for this style of end mill when roughing ferrous and non-ferrous workpieces before a finishing pass.

This end mill fits standard roughing operations on vertical mills, knee mills, and CNC machining centers. Its regular-length geometry and single-end construction are common in job shops, maintenance machining environments, and production facilities running moderate material removal cycles. The non-centercutting design means it is intended for peripheral cutting and side milling rather than plunge cutting. The REM445 series designation places it within a recognized line of cobalt roughing tools used across general metalworking applications.

Key Features

• M42 cobalt construction for improved heat and wear resistance compared to standard HSS
• Four flutes with right-hand cutting and right-hand helix for standard milling operations
• Bright/uncoated finish suitable for a wide range of workpiece materials
• Non-centercutting, single-end design optimized for peripheral and side milling
• Regular length geometry with a 3/8 inch shank for broad toolholder compatibility
• Mill diameter tolerance of +0.003 to -0.000 inches for consistent fit and performance

Compatibility

Designed as an OEM-style roughing end mill for use in standard 3/8 inch collets, end mill holders, or compatible toolholding systems on vertical and CNC milling machines.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine before changing tooling. Ensure the shank is fully seated and properly torqued in the toolholder per the holder manufacturer's specifications. Verify runout after installation before beginning a cut, and confirm spindle direction matches the right-hand cutting configuration of this tool.
