Knowing your blade
Front angle
The front angle is the number of degrees of the tooth in relations to the centre line of the saw blade
22 - 30° - Ripping of dry and green wood
5 - 15° - Crosscutting of wood, sizing of fibreboard, plasterboard, chipboard, veneered board and plywood
6 - 10° - Cutting hard plastics, veneered and laminated boards, mitre-cutting of wood and non-ferrous metals with automatic feeding
Negative 2 -5° - Cutting of metals with manual feeding as well as plastic and laminate

Tooth Pitch
Tooth pitch is an important factor when choosing blades for different types of work. The pitch is the distance between the front faces of adjacent teeth. The formula to the right can be used for calculating pitch
Designation “special”
| SPECIAL | DESCRIPTION |
|---|---|
| L | Laser dampened saw body. The saw blades are designed with thin laser-cuts. These reduce the noice and vibrations bye up to 40% |
| B2 | Large cutting width |
| T2 | Small cutting width |
| T3 | Extra small cutting width |
| T4 | Extremely small cutting width (with limited cutting depth) |
| S | Saw blades with guard teeth |
| R | Wiper slots saw blades |
| SR | Wiper slots saw blades with guard teeth |
| E | Dampened saw blade. Reduced gullets to reduce noise. |
Cutting Speed / Feed per Tooth
To optimise long life and good surface finish it is crucial to use the correct feed per tooth. If the wsaw blade has to low feed it results in quick wear. If the feed is to high it can cause teeth to break.
The recommendation table to the right, state cutting speed and feed rate per tooth for some different materials.
| MATERIAL | Cutting Speed [m/sec] | Feed rate per tooth [mm] |
