The Bosch Expert AVZ 90 RT Starlock Oscillating Multi Tool Sanding Plate is designed for multiple materials and users. The coarse, open grains of the RT2 (grit size 20) are best for removing mortar behind tiles; removing carpet adhesive; or rough shaping of wood. The RT4 (grit size 40) is best for removing thick paint but can also tackle mortar and glue if required. The RT6 (grit size 60) is the paint specialist, while the RT10 (grit size 100) is ideal for sanding and preparing clean wood surfaces.

OIS vs Starlock Accessory Fitment System	OIS Accessories are the standard accessory fitment system for many oscillating multi tools and will only fit OIS multi tools. Starlock Accessories are a newer type of accessory fitment system developed by Bosch and Fein which is now the standard for a number of brands. It is much more robust than the older OIS system with less weakness in the connection and as such allows for longer and stronger accessories. They still retain the OIS holes so therefore will fit both Starlock and OIS multi tools. Starlock Plus Accessories can be longer than OIS accessories due to improvements around the fitting mechanism, they will only fit Starlock Plus or Starlock Max multi tools and are generally for heavier duty work. They will not fit OIS or Starlock multi tools. Starlock Max Accessories are the heaviest duty accessory and will only fit Starlock Max multi tools. Again they can be longer and stronger due both to the starlock fitting system and the power of the machines. They will not fit OIS, Starlock or Starlock Plus multi tools.
