The SU2-SP characteristics of stainless steel spiral wire attack are as follows：
1、 For the characteristics of hard cutting of stainless steel, such as SUS316 and SUS317, the high speed steel with heat resistance and wear resistance is used for silk tapping.
2、 In order to reduce the cutting resistance and the cutting heat, the thread has the design of the clearance angle, and the acidification treatment is applied to prevent the dissolving of the silk attack surface.
3、 There will be a contraction of the tendency of general tapping, design Bensi attack accuracy has a moderate increase of.
4、 Bensi attack by BLF (thread completely 3 teeth mountain in addition to the effective diameter of the threaded grinding position) to reduce the broken tooth shape, caused by bad chip discharge.
