Review on POWERTEC 4R13518 50 Sander Festool 133Mm by Andy Tran

This is my favorite Festool sanding sheet. Lasts a long time in dust extraction. Stay away from glue and paint, otherwise the sheet will stick together. I keep a variety of grains on hand. I have had no problems with all sizes of Powertec abrasives. Good value for money, I tried the brands Festool, Mirka, Abranet and Powetec. All did well. They are comparable to Festool Rubin2 panels and are mainly intended for wood. I would like Powertec to sell the Festool hole pattern for the RO90/DX93 and DTS400 grinders. I buy the same brand of grinders Festool RO125, RO150, ETS125 and RTS400.
