Professional Metal Bond Diamonds for Extra Hard Concrete

Lavina Gold Metal Bond Diamonds are designed specifically for grinding extra hard concrete with a Mohs hardness rating of 7–8. The Gold extra soft bond is engineered to maintain efficient cutting performance on dense concrete while delivering controlled and consistent wear. This makes the tools ideal for floor preparation, coating removal and the initial stages of concrete polishing on extra hard concrete surfaces.

Available in a range of grits, these Lavina Quick Change diamond tools allow you to progressively refine the concrete surface before transitioning to ceramic, copper or resin bond tooling. Choosing the correct bond for the concrete hardness helps maximise cutting efficiency, reduce glazing and produce a more consistent scratch pattern throughout the grinding process.

Choosing Single or Double Segment Tools

The tools are available in Single Segment and Double Segment configurations. Single Segment tools are generally recommended for floor grinders under 30″ or where a more aggressive cut is required. Double Segment tools are better suited to larger machines with a working width of 30″ and above, providing balanced grinding performance and extended tool life.

Lavina Quick Change System

Featuring the Lavina Quick Change fitting system, these diamond tools can be installed and changed quickly, helping to minimise downtime. If you are using a different manufacturer’s floor grinder, we can also supply conversion plates that allow Lavina Quick Change tooling to be used with many other professional grinding machines.

Selecting the Correct Bond

For the best results, always match the bond to the concrete hardness and select the appropriate grit for the required level of aggregate exposure and desired finish. Where the concrete hardness is unknown, testing the floor before grinding can help ensure the correct metal bond is selected.
