Seco 17004614 Roughing End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The SECO 17004614 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from solid carbide, this tool features four spiral flutes with a fine pitch and a right-hand cutting direction, making it suited for high-feed roughing passes on ferrous and non-ferrous materials. The bright, uncoated finish means it ships ready to use without additional prep. At 0.25 inches in diameter with a 0.375-inch length of cut and 2 inches overall length, it fits standard tool holders equipped for a Weldon flat shank. Center-cutting capability allows plunge entry when the application requires it.

This end mill is intended for use in machining centers and manual milling machines where a compact, small-diameter roughing tool is needed. The 1/4-inch shank diameter with a Weldon flat seats securely in side-lock holders, reducing tool pull-out risk during heavy cuts. It is appropriate for production shops, toolrooms, and maintenance machining environments. The Series SR420 designation places it within a defined family of fine-pitch roughing tools optimized for chip clearance and reduced radial load during slotting and peripheral milling cuts.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Four spiral flutes with fine pitch for improved chip evacuation during roughing
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Weldon flat shank reduces tool pull-out in side-lock holders
• Right-hand flute and right-hand cutting direction for standard spindle use
• Bright, uncoated finish suitable for a wide range of workpiece materials

Compatibility

Designed as a direct-fit replacement or standard tooling option for milling setups that accept a 1/4-inch Weldon flat shank end mill in a side-lock or set-screw style tool holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before inserting the end mill. Torque the Weldon flat set screw to the holder manufacturer's specification. Confirm runout with a dial indicator before beginning any cut, and follow the machine tool builder's guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material.
