Seco 17004662 Roughing End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The SECO 17004662 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from solid carbide with an AlTiN coating, it handles high-heat cutting environments and extends tool life in ferrous and hard materials. The 1/4 inch mill diameter and 4-flute spiral configuration deliver a fine-pitch cut at a right-hand cutting direction, making it suited for finish-quality roughing passes. A Weldon flat shank provides positive drive and resists pullout in demanding setups. This tool is typically installed and operated by machinists and CNC programmers in job shop and production environments.

The 17004662 is intended for use in vertical and horizontal milling machines, CNC machining centers, and manual mills where a 1/4 inch solid carbide end mill is required. Its 3/8 inch length of cut and 2 inch overall length make it well suited for shallow-pocket and peripheral milling applications where rigidity and runout control are priorities. The AlTiN coating supports dry machining and high-speed applications in alloy steels, stainless steels, and similar materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating enhances heat resistance and extends tool life in high-speed applications
• 4-flute fine-pitch spiral design for efficient chip evacuation and smooth roughing passes
• Weldon flat shank resists rotational pullout under heavy cutting loads
• Center-cutting capability allows plunge entry without a pre-drilled pilot hole
• 45-degree chamfer angle and 20-degree maximum helix angle suit a range of milling strategies

Compatibility

Designed as an OEM-style replacement or direct-fit option for 1/4 inch solid carbide roughing end mill applications in standard ER and Weldon flat toolholders accepting a 1/4 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the Weldon flat shank fully into the holder and torque the set screw to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut, and confirm that the collet or toolholder is rated for the intended spindle speed.
