Description
The SECO 17004719 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from solid carbide with a TiCN coating, this tool delivers hardness and heat resistance suited to demanding cutting conditions. It features 3 flutes in a coarse-pitch, right-hand spiral configuration with a 30-degree maximum helix angle, producing efficient chip evacuation during roughing passes. The 1/2-inch mill diameter and 1/2-inch straight cylindrical shank make it compatible with standard collet and end mill holders. Machinists and tool-and-die professionals use this end mill in CNC and manual milling operations across a range of ferrous and non-ferrous materials.
This roughing end mill is suited for use in job shops, production machining, and maintenance repair environments where rapid stock removal is the priority before finishing passes. The centercutting design allows for plunge entry, adding versatility to the tool path. The coarse pitch geometry breaks chips aggressively, reducing cutting forces and heat buildup compared to standard-pitch end mills. Its regular-length body fits most standard milling setups without requiring extended-reach tooling or special adapters.

Compatibility
Designed as an OEM-style replacement and standard-fitment roughing end mill for use in CNC machining centers and manual mills accepting 1/2-inch straight cylindrical shank tooling. Part of the SECO AR330 series.
Installation Notes
Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the holder to the recommended engagement depth before tightening. Verify runout with a dial indicator after installation and before cutting. Always power down and lock out the spindle before changing tooling per applicable machine safety procedures.
