Review: Quality items - Carbide, cutters work awesome.They cut everything i've used them on
Review: Cuts very well and stays sharp for a long time - There's another review on here where a guy says this was the best purchase he ever made. That was exactly what I was thinking. I had a person that was coming to buy a van for me. And a couple weeks back I tried to resurface my own rotors. I got lazy and never test drove the van afterwards but the day she was supposed to come by I had about 4 hours and I went to drive the van and quickly realized that that rotor was not surfaced at all. The front end was shaking. I had a choice driving an hour to the nearest auto parts shop and pay $200 for a rotors or use the rotor that is on my van that is messed up superimpose it on a rotor that I tried to buy that had the wrong lug pattern on it and drill a lug pattern out. I didn't have regular bits that were big enough to drill out the holes. So I busted out this set used a center punch and very quickly drilled out the rotors. You could tell how good these bits are because of the size of the shavings that came out. I was able to do eight holes with one four amp hour drill battery and still had life in it. This carbide bit went through 3/8 of material in about less than a minute of time. I didn't even really put oil on it to keep it lubricated either. And after the eight holes it was still cutting. This is an amazing product and it saved my butt. Thank you so much to the maker.
