Top 6 Best Pneumatic Air Chamfer Tool!

What are Pneumatic Air Chamfer tools used for?

The pneumatic chamfering tool is an air-driven tool that is used for small holes and edge work. It is a compact and lightweight tool that is ideal for edge breaking and chamfer work on stainless steel and mild steel. These tools are used by DIY homeowners and construction professionals alike.

Why would you want chamfered edges?

Both fillets and chamfers serve to smooth sharp edges, reduce stress concentration, and enhance the load-bearing capacity of machined parts. However, chamfers have a higher stress concentration compared to fillets as they are unable to distribute stress over a larger surface area.

The term chamfer comes from middle French chamfrein, which is a variation of the beveled edge. While a beveled edge is a sloping edge that is not perpendicular to the object’s surfaces, a chamfered edge has a slight difference. A chamfered metal piece has a curved edge. Often times you hear these terms used interchangeably.

SI FANG  Portable Pneumatic Chamfering Tool

Rounding out our list is another quality pneumatic air chamfer tool crafted by SI FANG. This pneumatic chamfering machine is lightweight, weighing only 400g (0.88lb).

The air compressor (air pump) has an output of about 6~8kg. Traditional air compressors contain water and a small amount of lubricating oil. Without an oil-water separator, the water and oil will enter the machine and cause adhesion, slowing down the rotation and reducing speed and torque. To prevent this, inject pneumatic tool oil into the air inlet and let the machine idle for ten seconds before using it.
