Types of blades
Blades we can divide according to the hardness and chemical structure ot teeth tips. Every type of blades has its recommended field of using.
M42
It is bimetal blade M 42 ( EasyCut) with a new geometry and with a big saw setting that is teeth –breaking resistent . It is suitable for cutting of a wide range of materials ( steel, nonferrous metals, plasts, ..) There is possible to choose from three teeth sizes – easy choice of a blade.
M51
It is a blade with a big performance, universal blade M 51 with a long lifetime, suitable for cutting from constructional steel to middle alloy steel including stainless steel.Hook(H) version with a special geometry for cutting of nonferrous metals.
SP
It is a special bimetal blade M 51 for a highly alloyed materials , tool steel and special stainless steel. Teeth tips are made of HSS material – it causes a high temperature resistance.
Pitch of teeth
It is determined by the number of teeth for one inch and it is important for determining of a suitable blade for a cut section
To eliminate vibrations an intermittent teeth were developped. It means that every 25,4 mm ( 1 inch) smaller and bigger teeth pitch rotates. Blades with a constant teeth are used only for a special aplications, ( aluminium cutting – H version, or Universal type.
Choice of teeth
A table for a quick teeth number finding – the left column is siutable for cutting of full materials where the width of cut is important. In the right column we choose teeth according to the thickness of the of the side to be cut. When cutting bundles, thickness of sides count together.

Shift setting
Shift setting of the blade towards the cut is not exactly determined. It depends on many factors – hight of the blade, right adjusting,.... . It is possible to say, that the optimum shift is possible to adjust according to the chips shapes and colours, machine vibration, blade resonance, undercut.
a) thin or broken chips - increase the speed of feed or reduce the speed of a blade
b) - thick or blue chips - reduce the feed ,check cutting emulsion
- too spinny chips - full gaps between teeth, use saw-blade with bigger teeth, reduce feed or increase saw-blade speed
c) spiral chips - well set parametres
Notice : Too high speed of arm when cutting causes trembling of machine and its bigger noise.
Running -in of the blade
It is necessary to make round the sharp edge of teeth . This lowers the possibility of breaking and quick blunting of the blade.
When making the running-in , set the blade velocity according to the table No. 3. For first 30 minutes cut with the minimum shift and other 30 minutes increase fluently the shift velocity to an optimal one. The ideal running-in make with an easy machined steel ( classe 10,11)of the full section. The correct running-in highly increases the lifetime of the blade.
