Tapping is one of the most commonly performed processes in the production of internal threads. Most often, the manufacturing of a thread is described as an operation that can be easily accomplished. However, errors can occur simply by selecting the wrong tap for the material to be machined. In most cases, tapping is the last step in the manufacturing process. That is why tapping operations must conducted in a process-safe manner. A tool breakage during thread milling usually destroys the entire preceding output. To meet the high demands, it is necessary to develop precision tools that are suitable for universal applications while delivering improved performance and longer tool life.
Our range of taps includes taps for the production of precise through-hole and blind hole threads. Depending on the machining operation, different types of taps are required. To fulfill the diverse requirements, we offer several types of taps, including the following:
Our PM taps help you sustainably optimize your demanding machining tasks, and our taps made of HSS-E material feature suitable properties in terms of plastic deformability, toughness, and wear resistance.
The HSS-PM high-performance taps from our Professional Line feature an exceptionally smooth, high-performance coating and outstanding hardness. Due to their innovative geometry, they are suitable for universal application across a wide range of materials and can be utilized in machines with synchronous spindles, tension/compression compensation chucks, in thread-cutting machines and more. They achieve maximum cutting performance and process reliability with best chip evacuation.
Along with significantly greater process reliability, the taps feature an improved thread profile providing a longer load-bearing capacity of the thread. Depending on the material to be machined, the tool life of HSS-PM taps is also 30% to 70% longer. Furthermore, HSS-PM taps allow for higher cutting speeds and thus save additional time and costs during machining.
Hardlube coating is another feature of our PM taps, which facilitates chip flow along the flutes during tapping and counteracts chip jams.
Machine taps are used for thread cutting using a mechanized drive. The first step in thread milling is to prepare a core hole (blind hole or a through-hole) with subsequent tapping of the required thread using a tap.
Threading tools are made of high-speed steel (HSS). High-speed steels are offered with different alloying additions. The alloying element cobalt is of particular importance here. Steels with a cobalt content of 5% or 8 % constitute a separate alloy group. These grades are identified by the short designation HSS-E. HSS-E steels have a higher hardness and are best suitable for applications when a very high hot hardness and tempering resistance are required.
Also, for individual manufacturers or users working with small batch sizes, our range of HSS-E machine taps offers a full selection of machine taps. Our machine taps in metric DIN designs are suited for machining steel, stainless steel and cast materials.
* One critical issue in the day-to-day life of the user is a broken tap. Our solid carbide thread repair drill can help you solve the problem in a smart and efficient way.
