Description
The SECO 17014846 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel with a TiAlN coating, it handles elevated cutting temperatures and extends tool life in demanding applications. The 3/4 inch diameter, 4-flute geometry with right-hand spiral flutes and a 30-degree maximum helix angle produces efficient chip evacuation during roughing passes. With a 4.125 inch length of cut and a 6.375 inch overall length, this tool is suited for deep-pocket roughing where reach and rigidity are both required. Licensed machinists and CNC operators typically select this end mill for production roughing in machine shops and job shops.
This end mill is designed for roughing operations on milling machines and machining centers. The TiAlN coating improves wear resistance and heat dissipation, making it appropriate for dry or semi-dry cutting conditions at higher feed rates. The 3/4 inch shank diameter provides solid tool holding in standard ER or side-lock collet chucks. This is a non-centercutting tool, so it is not intended for plunge cutting. It is best suited for peripheral roughing, slotting entry via a ramp or helical path, and step-down roughing strategies.
Key Features
- M42 cobalt construction for elevated heat resistance and toughness in interrupted cuts
- TiAlN coating reduces friction and extends tool life in ferrous materials
- 4-flute, right-hand spiral geometry with 30-degree helix angle for efficient chip flow
- 4.125 inch length of cut supports deep-pocket and high-wall roughing
- Single-end design with 3/4 inch shank for direct chuck or collet mounting
- Non-centercutting requires ramped or helical entry, not direct plunge
Compatibility
Designed as an OEM-style roughing end mill compatible with standard 3/4 inch collet chucks, side-lock holders, and shrink-fit toolholders used on conventional and CNC vertical milling machines.
Installation Notes
Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the toolholder to the recommended gauge line and verify runout before cutting. Ensure the spindle is at a complete stop before tool changes. Consult the machine tool manufacturer and cutting tool data for appropriate speeds, feeds, and depth-of-cut parameters for the workpiece material.
