Stainless steel tapping
Stainless steel hand tapping SU-HT has a high degree of wear resistance, is designed with special cutting angles and groove shapes, and is acidified, so it is suitable for tapping of sticky, difficult-to-cut materials such as stainless steel. use.
Stainless steel spiral tapping SU-SP has the same characteristics and functions as SU-HT, and is designed with spiral grooves for blind hole tapping. The stainless steel tip tapping SU-PO has the same characteristics and functions as the SU-HT, and is designed with a spiral groove for through-hole tapping.
The characteristics of stainless steel spiral tapping SU2-SP are as follows:
1. In view of the characteristics of stainless steel materials such as SUS316 and SUS317 that are difficult to cut, the tapping uses high-speed steel with high heat resistance and wear resistance.
2. In order to reduce cutting resistance and cutting heat, the thread part has a clearance angle design, and the tapping surface is acidified to prevent melting.
3. Generally, there will be a tendency for the thread to shrink after tapping. The accuracy of this thread tapping is appropriately increased.
4. This tap adopts the BLF shape (the thread is completely threaded and then the thread is ground to the effective diameter position) to reduce the occurrence of chipping caused by poor chip discharge.
