FAQ

Where do I get a riving knife with 1.9 mm or 2.2 mm thickness?
In order to make things as easy as possible for you, we are directly offering a range of riving knives particularly
optimised for the SuperSilent. For a topical overview of available riving knives please have a look at our SuperSilent-
catalogue on our webpage.

Is it possible to use my riving knife with 1.9 mm thickness for the SuperSilent Ø 350?
No, it is too thin.

Is it possible to use my riving knife with 2.2 mm thickness for the SuperSilent Ø 300 / 303 mm?
If you are working with the SuperSilent version 2, this riving knife cannot be applied. Combined with
“Version 3, Ø 300” or “Type 7825, Ø 303” the riving knife can theoretically be applied, because these tools have a kerf
of 2.4 mm. The protrusion between riving knife and kerf would, however, be very small with only 0.1 mm on each side.
We therefore recommend to continue applying our riving knife with 1.9 mm thickness
I am afraid I cannot find a suitable riving knife in your programme. What next?
If a suitable riving knife cannot be found, we will be pleased to help you. Please contact us – the required riving knife
is possibly in stock meanwhile.
I received a riving knife from you. Why does it look completely different compared to the previously applied
riving knife?
Our riving knives are in most cases wider than the original riving knives of the machine manufacturers are. No need
to worry, because our riving knife is bigger than the original ones. This does in fact provide additional stability – an
important feature to avoid jamming of the workpiece. We strongly advise you against purchasing a ground riving knife,
because this does not provide the added stability.

My riving knife has been jamming ever since the first cut. How can I avoid that?
When designing a saw the machine manufacturers take account of a line between the centre of the saw blade and
the centre of the riving knife. This fictional centre line refers to conventional tools with the usual tooth protrusion. The
SuperSilent has a thinner saw body and a comparatively small tooth protrusion of only 0.1 mm (e.g. Version 2). With
some machines the riving knife is thus no longer in line with the saw blade. If the riving knife is off-centre as against
the saw blade this may lead to jamming. This mismatch can be corrected by means of a rust-free foil underneath the
riving knife. Alternatively the position of the riving knife can be changed on many machines by means of screws on the
riving knife holder.
