Just as good as the high end cutters. I’ve spent a kings ransom on multi-tool cutters over the years, always going for the professional range so I thought I’d take a punt on the cheap ones. VERY IMPRESSED with the cutters. I’ve cut wood, plastic and copper pipe and the cutter has kept its edge. I don’t envisage paying the extortionate prices of the high end cutters again and at this price once the edge has gone you can afford to discard the cutter and start with a fresh one rather than try to get a few more cuts out of an expensive one. They fit DeWalt just fine.
