One would think that I do not need an electrician saw, but this device facilitates a quite a lot, cut precise cable channels, smaller dimension can thus prima cut miter. Kitchen countertops clean cut to z. B. to mount hobs, lamp cutouts etc. The Staubaubsaugung works with a good vacuum cleaner fine. and all that handy in a suitcase. Although its cost Euro, but that one has quickly forgotten in the enthusiasm to work with this device.
