How to open small diameter stainless steel pipe?

1, small caliber stainless steel pipe opening is mainly part of the dynamic drilling, hydraulic, electric semi-automatic drilling.

2, with hydraulic drilling speed is relatively fast, the drilling effect is beautiful, smooth without burr.

3, adjustable hand drill can also drill stainless steel, the key is to use what drill, can buy alloy drill

Note: Stainless steel is characterized by high toughness and easy to stick knives. Therefore, it is required that the hardness of the drill bit be high, the surface finish is good, and the tip Angle of the drill bit is larger than that of the ordinary drill bit (between 130 and 135 degrees). At the same time, the cooling should be sufficient. And the feed quantity is greater than 0.15mm in order to avoid cold work hardening layer cutting as far as possible. The cutting speed is as low as possible to reduce the cutting temperature. The cutting fluid is made of thick emulsion. Commonly used to process stainless steel drill bits are: high cobalt drill bits (M35 drill bit, M42 drill bit).. Among them, M42 bit is the most cost-effective, and carbide bit can also be used.
