Details are ok, but not quite. The seller states them for the SG-55 cutter and yes they bolt on and will fit. DETAILS is where I'm lowering my rating and you should beware. These tips come in a variety of sizes depending on the amperage of your machine. For example a 0.9mm tip for a 40A machine, a 1.0mm tip for a typical 50A machine and a 1.2mm tip for a 60A machine . Yes, they will fit, but they may not fit your machine's hole size. I learned this the hard way when I was cutting for the first…
