Robbjack TS-401-16 Square End Mill 1/2 in 4 Flute Carbide

Product Description

The ROBBJACK TS-401-16 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. Built to Series TS-401 specifications, this tool features a 0.5 inch cutting diameter, a 0.625 inch length of cut, and a 3 inch overall length, making it a stub-length tool suited for rigidity-critical applications. The 4-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows for direct plunge entry. This end mill is installed and operated by machinists and tool-and-die professionals in CNC and manual milling environments.

The TS-401-16 is intended for use in general-purpose milling, slotting, profiling, and contouring applications where a stub-length tool improves deflection resistance. The 0.5 inch shank diameter mates with standard ER collets, end mill holders, and shrink-fit toolholders. Uncoated solid carbide construction makes this tool well suited for applications where post-coating is applied by the end user or where bare carbide is preferred for the workpiece material.

Key Features

• Solid carbide construction for high rigidity and wear resistance
• 4-flute spiral design with 30-degree helix angle for efficient chip flow
• Centercutting geometry allows direct plunge cutting
• Right-hand cut and right-hand flute orientation for standard spindle use
• Stub length overall reduces deflection in tight setups
• Uncoated finish suitable for selective coating or bare-carbide applications

Compatibility

Designed as an OEM-style solid carbide square end mill in the ROBBJACK TS-401 series, compatible with standard 0.5 inch end mill holders, ER collet chucks, and shrink-fit tooling systems used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully powered down and locked out before tool changes. Ensure the shank is fully seated in the toolholder to the recommended grip length and that set screws or collet nuts are torqued per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and depth of cut.
