The dimensions shown in the photo are examples. The actual dimensionscan be found in the product description.


The bi-metal hole saw is used for drilling holes in materials such as metal, stainless steel, non-ferrous metals, aluminium, wood and plastic. The holes are made of high-quality HSS high-speed steel. The correct rake angle and tooth spacing ensure efficient and fast hole drilling. When using the hole saw , it is important to use the correct coolant and adjust the rotational speed to the material to be drilled.
