Bosch EXPERT MATI 68 RD4 Starlock Max Oscillating Multi Tool Grout Blade
The Bosch EXPERT MATI 68 RD4 Starlock Max Oscillating Multi Tool Grout Blade is a professional-grade accessory designed for tilers, bathroom fitters, and kitchen installers who demand precision and longevity from their tools.
Engineered with Bosch Diamond Technology, high-quality diamond grits are bonded to a robust steel body, delivering exceptional durability and cutting performance that lasts up to 10x longer than the Bosch ACZ 85 MT4 laser-melted carbide blade. The pointed blade geometry allows effortless access into corners and around fittings — areas that standard blades struggle to reach.
The RD4 configuration is designed for regular-thickness grout of 2.3mm and larger, making it the go-to choice for most standard tiling applications. Available individually or in a pack of 10, this blade suits both occasional tradespeople and those working on high-volume projects.
Features and Benefits:
• Long life in grout and soft tile cutting
• Bosch Diamond Technology — high-quality diamond grits fixed to a steel body for outstanding durability
• Pointed blade design allows precise work in corners and around fittings
• Flat mount eliminates wobbling for a controlled, accurate cut
• Starlock Max mount for maximum power transfer and blade changes 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.
