Solid Carbide Thread Mills

Thread mills are used to produce threads on machining centers which are capable of helical interpolation.  The benefits of thread milling versus tapping are specific to the needs of the customer.  Short run jobs especially in expensive parts where thread finish is critical are favorable for thread milling. Difficult to machine materials such as inconel, hard steels or titanium and short run jobs requiring taper pipe threads can be thread milled with good results.

One mill can be used for various diameters requiring the same pitch. That is a 20 pitch thread mill can be used to produce a ¼-20 NC, 7/16-20NC or ½-20 NC thread in different classes of fit and a variety of materials either Right Hand or Left Hand threads. This offers great flexibility when a small number of parts are threaded.

Regal’s  solid carbide AlTin coated thread mills are helical fluted to cut freely like an end mill and with AlTin multi-layer coating provide much longer tool life and allow milling in harder materials.

Styles include all UN and Metric thread forms as well as NPT and NPTF.  Heavy duty and coolant feeding thread mills with AlTin coating are also inventoried at our Roscoe, IL facility.  Regal’s technical support staff is available to assist in programming for our thread mills.
