Seco 17014255 Roughing End Mill 1.5 in 6 Flute Cobalt

Product Description

The SECO 17014255 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 delivers thermal resistance and edge retention in ferrous and difficult-to-machine materials. The cutter measures 1.5 inches in diameter with a 1.5-inch length of cut and a 0.75-inch shank diameter, giving it the rigidity needed for heavy roughing passes. Six right-hand spiral flutes with a 30-degree maximum helix angle promote efficient chip evacuation. This tool is installed and used by machinists and tool-and-die professionals in production and job-shop environments.

This roughing end mill is suited for peripheral milling, slotting, and profile roughing on mills, VMCs, and HMCs. Its non-centercutting design means it is intended for side milling operations rather than plunge cuts. The 3.75-inch overall length accommodates standard toolholding setups without requiring extended-reach adapters. The bright finish keeps the tool free of coatings that could interfere with close-tolerance setups. Machinists working on steel, alloy steel, and similar ferrous workpieces will find this cutter appropriate for pre-finish stock removal passes.

Key Features

• M42 cobalt HSS construction for elevated heat resistance during high-feed roughing
• 6 right-hand spiral flutes at 30-degree maximum helix for aggressive chip evacuation
• 1.5-inch diameter with 1.5-inch length of cut for substantial depth-of-cut capability
• 0.75-inch shank diameter for compatibility with standard end mill holders and collets
• Bright, uncoated finish suitable for use with cutting fluids on ferrous materials
• Single-end, non-centercutting design optimized for peripheral and profile roughing

Compatibility

Designed as an OEM-style replacement and standard tooling option for single-end roughing end mill applications requiring a 0.75-inch shank and 1.5-inch cutting diameter in standard end mill holders.

Installation Notes

This end mill is installed by qualified machinists following standard machine tool safety procedures. Secure the 0.75-inch shank in a properly sized end mill holder or collet chuck, torquing to the toolholder specification. Confirm spindle direction is set to right-hand rotation before engaging the cut. The non-centercutting geometry requires the cutter to be engaged from the side — do not use for direct plunge operations.
