2D batch head, imported S2 alloy steel material, high hardness
High precision, good fit, non-slip wire
Aluminum Drill 2D Series Bits
Different from the production process used in the previous batch head, the overall cutting step cutting process is adopted to make the head completely fit the screw, which can effectively prevent the occurrence of slippage during the application process, and when the screw is prone to rust and slippage. When there are problems, such as silk, it can be received by more contacts.
The surface is easily twisted, the screws are removed, and the operation is lighter and more comfortable.
