Bosch EXPERT AVZ 32 RT4 Starlock Oscillating Multi Tool Sanding Finger

The Bosch EXPERT AVZ 32 RT4 Starlock Oscillating Multi Tool Sanding Finger is a carbide-grit accessory designed for sanding in tight, hard-to-reach spaces where hand sanding is impractical.

Its extra-thin, pointed blade is built to reach into narrow gaps between floorboards, decking slats, window shutters and stair components — areas where conventional sanding tools simply cannot access. The pointed tip ensures full contact in the tightest niches, making it a practical choice for carpenters, painters and renovators working on detailed finishing tasks.

The blade uses Bosch's Carbide Technology, meaning the high-grade carbide grit remains sharp and effective over an extended working life. This RT4 variant carries a coarse grit size of 40, suited to material removal tasks such as stripping paint, with open-grain construction that resists clogging. When the surface does load up, soaking in solvent restores performance without replacing the blade.

The Starlock mount ensures optimum power transfer from compatible oscillating multi-tools and allows tool-free blade changes in around three seconds.
