Bosch PRO MATI 68 RT3 Starlock Max Oscillating Multi Tool Grout Blade

The Bosch PRO MATI 68 RT3 Starlock Max Oscillating Multi Tool Grout Blade is a carbide-grit grout removal blade designed for precision work in tiled surfaces, lasting up to 3x longer than the Bosch ACZ 85 MT4.

Built for tilers and contractors, this blade excels at removing old grout without causing damage to surrounding tiles — a task where accuracy matters as much as durability. Its tough carbide grit coating ensures effective performance in abrasive materials, delivering consistent results across extended use.

The distinctive D-shape profile sets this blade apart for awkward locations. It allows you to work cleanly into corners and manoeuvre around fixed objects such as tap handles on tiled bathroom walls — areas where a standard rectangular blade simply cannot reach.

Beyond grout removal, the PRO MATI 68 RT3 is also suitable for cutting cable channels in aerated concrete, making it a versatile addition to any multi-tool accessory kit. The Starlock Max mount ensures maximum power transfer from tool to blade and enables a convenient tool-free blade change in under 3 seconds.
