Robbjack TS-401-06 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The ROBBJACK TS-401-06 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Part of the TS-401 Tuffy series, this stub-length end mill features a 3/16 inch cutting diameter, a 3/8 inch length of cut, and a 2 inch overall length. With 4 spiral flutes, right-hand cut, right-hand flute direction, and a 30-degree helix angle, it delivers clean, efficient material removal. The uncoated solid carbide construction suits a wide range of general-purpose milling operations. This tool is installed and operated by machinists and CNC tooling professionals in shop and production environments.

The TS-401-06 is suited for slot milling, profiling, and plunge cuts in ferrous and non-ferrous materials. Its centercutting capability allows direct plunge entry without a pre-drilled hole. The stub length format provides added rigidity, reducing deflection in tight-tolerance applications. The straight cylindrical shank fits standard collet chucks and end mill holders commonly used in CNC machining centers and manual milling machines. This tool fits applications where a compact reach and solid carbide rigidity are priorities over extended projection.

Key Features

• Solid carbide Tuffy series construction for wear resistance in general-purpose milling
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design permits direct plunge milling without a pilot hole
• Stub length format increases rigidity and reduces tool deflection
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-specification solid carbide end mill in the ROBBJACK TS-401 series, compatible with standard collet chucks and end mill holders accepting a 3/16 inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify collet size matches the 3/16 inch shank diameter and torque the tool holder to the machine manufacturer's specification. Follow applicable shop safety standards and wear appropriate eye and face protection during operation.
