HM circular saw blades for cutting non-alloy, alloy and strongly-alloyed steel and stainless steel up to 380/400 HB hardness
Geometries and cutting angles specifically designed for cutting:
- tubes and profiles with medium - fine section
- tubes and profiles with medium - high section
- solid sections (rods, bars, billets, plates, sheets etc.)
Body blades steel
Steel used for the construction of the body blades is hot or cold rolled.
There are two main categories:
- 80CrV2: for medium / high applications with high stress
- 75Cr1: for standard applications
According to needs, the silencing slot with sound-absorbing material will be applied.
Availability of TIN, PVD, TIALN coatings
Teeth
The choice of high quality carbide, to be used for cutting different materials, is directed towards various types of quality of micro / fine / medium grain inserts, to ensure greater durability of the circular blade, greater resistance to shocks and limited wear of the tooth.
The mainly used cutting geometry is the trapezoidal-flat, in groups of four or five teeth, with nail or chip breaker groove.
Positive or negative cutting angles are designed to ensure optimal penetration into the material to be cut, with smaller radial and tangential angles, designed to reduce the wear of the tool.
We produce all sizes, number of teeth and thickness
Diameter: from 100 mm up to 2200 mm - Thickness: from 1 mm up to 15 mm
