This saw blade moves through wood as by air. It is quiet and even after a major test saw action still sharp. Longitudinal and cross-cutting approaches loosely alike. It runs perfectly round. A scorching, smoke, tars, charring the wood looking in vain for happiness. The low price could be related, that the teeth are brazed (brass, so certainly the speed limitation to 4500 U / min). If they stay in it, but is this all right with me! ;>) (The soldering looks clean and economical / crisp out!)
