Bosch PRO ACZ RT3 Starlock Oscillating Multi Tool Grout Blade
The Bosch PRO ACZ RT3 Starlock Oscillating Multi Tool Grout Blade is engineered for professionals who need precision and durability when removing old grout without damaging surrounding tiles. Using tough carbide grit, this blade cuts through abrasive materials efficiently while offering an impressively long service life — lasting up to 3x longer than the Bosch ACZ 85 MT4 Multitool Blade.
Beyond grout removal, the PRO ACZ RT3 is equally capable of cutting cable channels in aerated concrete, making it a versatile addition to any trade toolkit. The Starlock mount system ensures optimum power transfer from your multi-tool to the blade, and the tool-free blade change takes just 3 seconds — keeping your workflow moving on site.
Available in a single blade or a pack of 10 to suit individual jobs or ongoing professional use.
Features and Benefits:
• Lasts up to 3x longer than the Bosch ACZ 85 MT4 Multitool Blade
• Tough carbide grit for durability and effective cutting in abrasive materials
• Removes grout cleanly without damaging surrounding tiles
• Suitable for cutting cable channels in aerated concrete
• Starlock mount for optimum power transfer
• Convenient tool-free blade change in under 3 seconds
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.
