Regal Cutting Tools

The selection of carbide taps for high volume production was limited to materials such as brass, bronze and high silicon aluminum where abrasion was the cause of tool wear. The design required strength behind the cutting edge limiting the flute geometry and range of materials to be tapped. Regal’s carbide and carbo-clad taps are made from ultra fine-grain carbide with a high cobalt-content binder. This allows us to design taps with high shear cutting edges when needed to thread hard metal, Inconel and other materials. The combination of the sophisticated carbide grades with advanced multi-layered coatings is suitable for tapping at high speeds and ensuring unsurpassed productivity. Regal offers solid carbide taps up to 38” from our catalog, and above that size brazes carbide blades to HSS bodies up to 1 ½”. NPT and NPTF pipes sizes are available as well. As is always the case, special taps to meet your specifications are made and coated in less than two weeks.

Dies are used to cut or clean an external thread. They can be used by hand or on live spindles and are made of High Speed Steel.

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

Available in spiral point and spiral flute styles for a variety of difficult materials. The combination of flute design, particle metal and close tolerances produce superior performance at high speeds. Chip evacuation and thread quality are enhanced with the oxide treatment on these taps.

Spiral flute taps are designed to lift chips out of a threaded hole while allowing adequate coolant to get to the cutting action. Recommended for tapping stringy material particularly in blind holes.

Pipe threads are used when joining units intended to accommodate the flow of liquids or gases, such as fuel, oil, water or compressed air. Some internal pipe threads are straight; however, the majority of these assemblies feature tapered threads which have inherent design which makes tapping more difficult than straight threads. When tapping taper pipe threads, every tooth of the tap engaged with the work is cutting until the rotation is stopped. Because these threads are used in a variety of materials and frequently the parts produced are high volume, Regal has designed a number of different styles specific for various materials to insure quality parts while optimizing production and cost of parts produced. Regal provides low, medium and high hook pipe taps, as well as interrupted thread tools which reduces chip packing when the tap is fully engaged. Extension shank taper pipe taps are also immediately available. Our 24 hour special program includes special pipe tap production of special projections, and either right or left hand tapered or straight threads.
