Aluminum alloy
The EM provides a special cutting tap for blind hole/touch base (Enorm) and Rekord b-al design. It is absolutely necessary to chip in axial direction during the machining of long cutting aluminum. Aside from the big dip, these tools are made with fewer flutes so that more space can be used to make chips. This helps to avoid blocking the flute in the cut thread operation.

8-8 coating – diamond type, amorphous carbon coating
In the PVD process, the coating thickness of 1-2 meters can be achieved. Hardness is the covenant. 2500 high pressure. This single-layer coating is an excellent choice for non-ferrous and aluminum-silicon content (less than 9%). Because of the small friction, the adhesive force of the material is greatly reduced.
EM Z geometry is a very aggressive cutting geometry, with a high Angle and relief Angle, suitable for a large number of long cutting materials. It is specially designed for CNC machine tools. Synchronous feed control, especially the holder of the collet of the EM’s soft sync series, will bring the full performance potential of these tools.
For stainless steel materials, EM recommends high performance paint with GLT – 1. The z-faucet of the gDlt-1 coating produces a consistent, controllable chip structure that can be ejected smoothly and efficiently from the faucet. The gDlt-1 has a unique multi-layered structure with a top layer of anti-friction. The abrasion resistance and heat resistance of the coatings and the outer friction layer produce a more durable tool that requires less torque and produces better threads for quality.
The EM Z tap is designed for blind hole threads for long – cut materials. A fast spiral flow provides a good chip out of a blind hole. According to design and size, you can reduce up to 3 x D threads. It is not recommended to use a diameter increasing thread.
