Seco 17014093 Roughing End Mill 9/16 in 4 Flute Cobalt

Product Description

The SECO 17014093 is a single-end cobalt roughing end mill designed for aggressive material removal in ferrous and tough alloy applications. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS tools cannot match. The mill measures 9/16 inch (0.5625 inch) in diameter with a 1/2 inch shank, a 1-3/8 inch length of cut, and a 3-3/8 inch overall length. The bright/uncoated finish and 4-flute, right-hand spiral geometry make it well suited for roughing passes where chip evacuation and tool durability are the primary concerns. It weighs 0.3 pounds. This tool is installed by machinists and tool-and-die professionals working in job shop and production environments.

This end mill is used in vertical and horizontal milling machines, knee mills, and CNC machining centers for roughing operations on steel, stainless, and similar hard-to-machine alloys. The REM710 series regular-length geometry fits standard toolholders with a 1/2 inch bore. The 30-degree maximum helix angle supports stable cutting at higher chip loads typical of roughing work. It is not center-cutting and is not intended for plunge entry without a pre-drilled pilot hole.

Key Features

• M42 cobalt HSS construction for elevated heat resistance and edge retention in tough alloys
• 4-flute right-hand spiral geometry optimized for roughing passes and high chip load
• 9/16 inch mill diameter with 1/2 inch shank for standard toolholder compatibility
• Bright/uncoated finish suitable for applications where coatings are not required
• 30-degree maximum helix angle for stable cutting action during aggressive material removal
• Single-end design, regular length series REM710

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for milling machines and CNC machining centers accepting a 1/2 inch shank toolholder.

Installation Notes

Installation is performed by qualified machinists using appropriate end mill holders or collet chucks rated for the 1/2 inch shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout with a dial indicator after seating the tool to confirm proper alignment. This tool is not center-cutting and must not be used for direct plunge cuts without a pre-drilled entry point.
