Seco 17004667 Roughing End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The SECO 17004667 is a single-end roughing end mill engineered for aggressive material removal in demanding machining environments. Built from solid carbide with an AlTiN coating, it delivers heat resistance and extended tool life at elevated cutting speeds. The 3/8-inch diameter cutter features 4 flutes in a right-hand spiral configuration with a fine pitch and a 20-degree maximum helix angle. The 45-degree chamfer angle and 0.0200-inch chamfer width contribute to controlled chip formation. With a 1-inch length of cut and 2.5-inch overall length, this end mill suits compact workholding setups and tight-clearance applications where rigidity and precision matter.

This end mill is intended for use in CNC machining centers and manual mills where roughing passes demand consistent chip evacuation and tool stability. The Weldon flat shank provides positive drive and minimizes pullout risk under heavy side loads. The AlTiN coating makes it well-suited for cutting ferrous materials, hardened steels, and high-temperature alloys. Machinists and toolroom technicians working in job shops, production facilities, and tool and die environments will find this tool appropriate for slot milling, peripheral roughing, and step milling operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard material applications
• AlTiN coating provides high-heat resistance and extended tool life in dry or minimal-lubrication cutting
• 4-flute fine-pitch spiral design promotes efficient chip evacuation during roughing passes
• Weldon flat shank reduces tool pullout risk under high side-load conditions
• Center-cutting geometry allows plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style solid carbide roughing end mill suitable for use in standard 3/8-inch collet chucks and Weldon flat tool holders on CNC machining centers and knee mills.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Secure the Weldon flat shank in a properly sized end mill holder and torque the set screw to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning the cut. Always power down the spindle and confirm the machine is in a safe state before changing tooling.
