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 time and found that they didn't work as nice and neatly as my machine normally does. I then checked carefully and found that they sent me 1.2mm tips and not the 1.0mm tips my SG-55 head requires. So be careful and make sure you get the right size parts from the seller so you can insure. get the right product for your machine. I threw my money at her. They do NOT match what I need and I could not make out the seller's incomplete product description which never stated the critical hole size. The spacing guide I received is NOT the one shown in the picture and the one provided will work on my machine. This is a solid piece with holes on the sides, not the open wire type shown in the picture. I used one of these for five minutes which made me realize it was wrong so I can't return it as only new and unused parts can be returned. Save money and don't repeat my mistake. Before ordering, make sure you have the correct nozzle size for your machine size. The seller should really state the diameter of the tip as this is a critical number that the user needs to know.
