Horn 304 Milling System for Small Threads

Horn’s 304 circular milling system insert is designed to operate in diameters of 8 mm (0.315"). The precision tools are available as partial and full-profile versions to produce threads by helical interpolation.

Triple-edged inserts in the 304 system exist for groove milling, finish boring and chamfering, while these threading inserts spin on a diameter of 7.7 mm (0.303"). The company says the vibration-dampening carbide shanks with integral through-coolant ports make the system versatile and easy to use.

The Horn circular milling system is said to offer a variety of process advantages, including fast, reliable tooling for producing good surface finishes. During the machining process, the tool plunges into the material either at an angle or almost horizontally and is then driven on a helical path. Threads can be manufactured at a highly reproducable level of consistent quality, the company says.

Circular interpolation has a range of applications and can be more economical when strategically applied when machining steel, special steels, titanium and alloys. Horn’s circular milling tools are engineered for precision machining of grooves, threads, t-slots, profile milling and other circular interpolation processes.
