Description of product notes
Stainless steel hand wire attack SU-HT has high wear resistance. It has special cutting angle and groove shape after design, and is acidified. Therefore, it is suitable for tapping processing with sticky hard materials such as stainless steel.
The stainless steel spiral wire attack SU-SP/SU+SP has the same characteristics and functions as SU-HT, and has been designed with spiral grooves for the use of impacting holes.
The stainless steel first end tapping SU-PO has the same characteristics and functions as SU-HT, and has been designed with spiral grooves for the use of through holes.
The SU2-SP features of stainless steel screw tapping are as follows:
1. High speed steel with heat resistance and wear resistance is used for the characteristics of hard cutting of stainless steel, such as SUS316 and SUS317.
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, general tapping will tend to shrink, 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.
