Review on 🔧 POWERTEC 45004 A/O Hook and Loop 8 Hole Disc, 5-Inch, 40 Grit, 25 Pack by Lawrence Reuter

I've had mixed results with my recent purchase of 60 grit PowerTec abrasive discs. Luckily about 75% of them worked properly. But some didn't hold up well on the grinder's velcro (and changing the velcro didn't help). Also, some discs left a lot of "wool" fibers in the Velcro that I had to clean with a brass brush. When I bought it a few months ago, there were no such problems. Hopefully velcro issues are limited to this last batch. Update October 2018 (a year later): I bought 80 grit for another project and have no issues with velcro. So I increased the rating by one star (now four stars).
