Bi-metal hole saws are best for cutting metal and wood. The best results are achieved with maximum values in steel. 5.0mm material thickness. With the bimetal hole saw HSSE-Co 8, you can also cut stainless steel - but only in sheets at most. 1.5mm!
The fields of application are mainly sanitary and electrical equipment.
When cutting steel or metal, pay attention to the correct number of revolutions. In the speed table of the bimetal hole saw you will find the corresponding speed.
Bi-metal hole saw HSS with different teeth
With easy-to-cut materials such as aluminum, wood or drywall, different teeth allow for better removal of cut material. Compared to the bimetal hole saw HSSE-Co 8 with fine teeth, the cut is slightly thicker.
It is commonly used to drill holes for sockets and light switches (68mm diameter) and cable ducts on tables or kitchen benches.
Bi-metal hole saw with fine teeth HSSE-Co 8
High cobalt content ensures high hot hardness. This means that tool steel does not lose hardness at high temperatures.
Fine teeth ensure smoother operation, better cutting patterns, and less work.
For these two reasons (high hot hardness and clean cut), the bimetal hole saw HSSE-Co 8 is particularly suitable for soft metals such as unalloyed and alloyed steels (up to 5 mm), stainless steel (up to 1.5 mm).
Compared to bi-metal hole saw HSS, the heat generated during cutting is lower, resulting in longer life, especially for metal.
