Bosch EXPERT AVZ 70 RT4 Starlock Oscillating Multi Tool Abrasive and Grout Removal Blade

The Bosch EXPERT AVZ 70 RT4 is a Starlock oscillating multi-tool blade designed for tile removal and repair work, combining grout cutting, corner access, and mortar removal in a single accessory.

Its distinctive teardrop shape with a pointed tip makes it well suited to three separate stages of tile repair. The carbide grit edge cuts through grout lines efficiently, while the pointed tip reaches into tight corners and awkward recesses that other blades cannot access.

Once the tile has been freed, the blade doubles as a sanding plate to grind away the old mortar bed, preparing the surface for a new tile. This multi-function capability reduces the number of accessories a tiler needs to carry on site, saving time and improving workflow.

Fitted with a Starlock mount, the blade transfers power directly from the tool with no energy loss, and can be swapped out in around three seconds without the need for tools. Compatible with Starlock and Starlock Plus oscillating multi-tools, it is a practical choice for tilers, contractors, and skilled tradespeople carrying out tile repair and refurbishment work.
