Seco 17014066 Roughing End Mill 1/4 in 4 Flute Cobalt

Product Description

The SECO 17014066 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge toughness in demanding cuts. The 4-flute spiral configuration with a 30-degree maximum helix angle produces efficient chip evacuation while maintaining surface control. The bright, uncoated finish suits a wide range of ferrous and non-ferrous materials. With a 0.2500-inch mill diameter and a 1.2500-inch length of cut, this tool is sized for precise slotting and profiling passes in standard vertical and horizontal milling setups.

This roughing end mill is suited for production and job shop environments where machinists need reliable stock removal in steel, stainless, and similar alloys. The 3/8-inch shank diameter fits standard R8, collet chuck, and end mill holder tooling common in manual and CNC milling machines. Right-hand cutting and right-hand flute direction make it compatible with conventional spindle rotation. The regular-length designation keeps it rigid in setups where reach is not a limiting factor, reducing vibration and deflection during heavy cuts.

Key Features

• M42 cobalt high-speed steel construction for elevated heat and wear resistance
• 4-flute spiral design with 30-degree maximum helix angle for efficient chip evacuation
• Bright, uncoated finish compatible with a broad range of workpiece materials
• Single-end, right-hand cut with right-hand flute direction for standard spindle use
• Regular-length body provides rigidity and reduces deflection in heavy roughing passes
• Series REM710 designation for straightforward replacement and reorder identification

Compatibility

Designed as a standard-shank roughing end mill with a 3/8-inch shank diameter, compatible with collet chucks, R8 holders, and end mill holders sized for 3/8-inch tooling on manual and CNC milling machines.

Installation Notes

Installation is performed by qualified machinists following standard toolroom procedures. Ensure the spindle is fully powered down and locked before inserting or removing the end mill from the holder. Verify holder runout with a dial indicator before initiating cuts, as excessive runout accelerates edge wear on cobalt tooling. Do not use this tool for center-drilling or plunge entry, as it is not centercutting.
