Werkmaster is not the best for the job. It's rigid, high speed and light. You can run circles around a werkmaster with a 175 rpm swing machine when it comes to refinishing and polishing (without removing lippage). For specialty jobs like grinding in place, concrete, etc. werkmaster definitely has it's place.
This video represents everything wrong with the refinishing industry. It's not rocket science, but you have to have a brain, a little common sense. A soft pad with with a ton of weight on top of it will never create a flat surface, you're just pushing it down as hard as you can and it will follow the different hardness of the minerals in the stone.
For companies to present these pads the way hey do is irresponsible and just plain BS. They have their place, but not for what they are presented as.
Here are a couple floors done with a 175rpm, 110v swing machine and diamond abrasives. Standard machine, cheap diamonds, 5x, home depot vacuum, etc. Nothing fancy. You don't need fancy equipment to do good work.
Notice the clarity. No orange peeling or texturing
