BAER HSSE-PM-TiN Forming Tap M 16 x 2.0 - DIN 376 with oil grooves

Forming taps are also known as fluteless taps. They produce particularly load-bearing internal threads in a non-cutting process. During thread forming, the polygonal profile compresses the material fibres and does not cut them, as is the case with thread cutting. This results in higher material strength and a smooth surface. Small forming pockets are formed at the tips of the resulting thread.

High frictional forces occur during thread forming, so it is essential to ensure sufficient lubrication. The oil grooves provide the necessary lubrication up to depths of 3.0 D.

Cold forming is not possible with all materials. Light metals, pure titanium, non-ferrous metals and steels, among others, are well suited. Since the required torques cannot be achieved by manual application, machine use is indispensable.

Advantages of forming taps

• No chips are produced
• Up to 20 times higher tool life time (compared to taps)
• Simultaneously for through hole and blind hole
• Wide range of materials can be machined
• Wrong cutting of the thread is impossible
• No pitch or flank angle errors
• Very true to gauge
• Higher strength of the holding thread due to material deformation or uninterrupted fibre flow
• Higher surface quality
• Much higher cutting speed
