Seco 17014200 Roughing End Mill 1/2 in 4 Flute Cobalt

Product Description

The SECO 17014200 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention suited to ferrous and hard-to-machine materials. The 1/2 inch diameter tool carries four spiral flutes with a right-hand cutting direction and a 30-degree maximum helix angle, producing the interrupted chip formation that defines roughing geometry. The bright, uncoated finish keeps the tool ready for use as received. Machinists and tool-and-die professionals install this mill in conventional vertical or horizontal milling machines and CNC machining centers for roughing passes before finishing operations.

This end mill is suited for shop environments where roughing cuts on steel, alloy steel, stainless, and similar materials are routine. The 2.5 inch length of cut accommodates moderate-depth side milling and slotting passes. The regular-length body and 1/2 inch straight shank fit standard collet chucks and end mill holders common across most machining setups. The Series REM710 designation identifies this as part of SECO's cobalt roughing line, and the single-end configuration means the tool is replaced rather than flipped when worn.

Key Features

• M42 cobalt construction for heat resistance and edge retention in hard materials
• Four spiral flutes with roughing geometry for high material removal rates
• 2.5 inch length of cut on a 4.5 inch overall length for moderate-depth passes
• Right-hand cut and right-hand flute direction, standard for most milling setups
• Bright uncoated finish, no additional preparation required before use
• 1/2 inch shank diameter matches standard collet and end mill holder bores

Compatibility

Designed as an OEM-style roughing end mill for use in standard 1/2 inch collet chucks and end mill holders on vertical mills, horizontal mills, and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practice. Power down and lock out the machine spindle before loading or changing the tool. Seat the shank fully in the holder and torque the retention hardware per the holder manufacturer's specification. Inspect the collet or holder bore for runout before taking the first cut, as excess runout accelerates wear on roughing geometry.
