Review on Astro 1221 Grinder Rotary Burr by Ronggolawe Denney

I had to grind material off the spindle to install the disc brake kit. I bought this kit and when it got here I was a bit shocked at its size, smaller than I expected. I was concerned that they would not be up to the task of polishing 45 year old metal. Boy did they surprise me, I used it straight away and it was more than up to the task. I used the cutters that came with it and after the first one the cut quality definitely went down because the second one took longer. However, the ridge isn't rubbish and I'm impressed that it hasn't deteriorated as much as I might have thought. At this point I would buy them again.
