2. How to choose the right Tap holder for Electric Tapping machine
Difference factory use difference screw taps, becuase of difference taps, the tap collets also have different standard.Mainly is ISO, JIS and DIN standard, It also have inch and ANSI standard.
ISO standard is mainly use in China and india country.
JIS standard is mainly use in Southeast Asia and Japan.
DIN standard is mainly use in Europe and South America
Inch size is It is British standard BSW.
ANSI standard is American Standard inch size.

3.What is the difference between Electric and Pneumatic tapping machines
Pneumatic tapping machines are suitable for small thread tapping applications, especially for sizes below M12, such as common specifications including M3, M4, M5, M6, and M8. For thread sizes larger than M8, an electric tapping machine is recommended, as it provides stronger power and more stable performance.Pneumatic tapping machines require connection to an air compressor, which results in relatively higher noise levels. In contrast, electric tapping machines operate more quietly. Electric tapping machines have now become the mainstream choice for threading operations.
