Lasts up to 100x longer than standard sandpaper - Tight gaps in decking, window shutters or old staircases are really difficult to sand by hand – and you usually end up getting a splinter in your fingers. With the EXPERT Sanding Finger, this kind of sanding is easy: the thin, pointed blade squeezes into the smallest spaces and sands quickly and effectively with its high quality carbide grit. Not only is the EXPERT Sanding Finger a great problem solver for carpenters, painters and renovators: it also offers an exceptional lifespan. Its grits are underpinned by Bosch Carbide Technology – hard metal that stays sharp and effective. Bosch EXPERT sanding fingers are a great time-saver for anyone needing to sand in tight spaces. The coarse, open grains of the RT4 (grit size 40) remove material such as paint with minimum clogging; while the finer grain RT10 (grit size 100) is ideal for sanding and preparing clean wood surfaces.
