Husqvarna Metal-Bonded Diamond Blocks
As with their other diamond products, Husqvarna’s tiered system provides a choice based on differing factors of performance and value. Vari-Grind blocks represent the silver rating, which has a different denomination of diamonds to allow more initial value. Vari-Grind blocks are at a lower price point but still have pro level performance.
The diamond pieces are much more hard-wearing than the metal block and base plate, therefore they are configured precisely according to the optimum grinding result.

Grinding materials
There is a grinding block for every job, whether you are grinding resins and adhesives or different grades of uncoated concrete. To see which blocks are best for which material please see Husqvarna’s Grinding Tools Guide.
Redi-Lock
Husqvarna diamond grinding blocks use the Redi-Lock® system, which is a tool-less method of attaching and removing diamond tools onto the holder disc.
As well as being able to go to site without tools, this also means a quicker changing of grinding blocks. With two or three passes with a grinding machine often required, the user would need to switch blocks after each pass. For example, creating a Hiperfloor Premium finish would require a set of 20 grit, 60 grit then 120 grit metal-bonded grinding blocks.
Redi-Lock is a robust system which is designed for easy administration whilst maintaining the strength and integrity of the diamond tooling.
