QuickChange Metal Bond Segment Tools

Superabrasive's metal bond tools feature fast aggressive cutting and long tool life. The QuickChange trapezoid pads easily slide in and out of the metal grinding heads without any bolting or extra plates needed. These tools can be used with LAVINA grinders as well as other grinders via a QuickChange adapter plate. For more details on the adapter plates so you can convert your grinder to Lavina QuickChange, go to Metal Plates and Foam Plates for other grinders.

The QuickChange Metal diamonds come in several metal bonds designed specifically for the different types of concrete hardness:

YELLOW BOND SERIES for SOFT concrete, typically under 2500 psi

Grit range: 6,14,30,50,70,120

  • Choose between one or two segments (buttons or bars) to control the speed and aggressiveness of the cut. 
  • Double button / bar tools are designed for heavier machines, and are not recommended for machines smaller than 25 inches. 
  • Single button / bar tools are designed for lighter machines, or where aggressive stock removal is required.
  • We recommend using single-segment tools for the first step even with heavier machines for faster opening of the concrete.

The QuickChange tool design for Lavina X machines fits also LAVINA S and LAVINA Pro models, but the old QuickChange tools designed for S and Pro machines are not compatible with the X-Series grinders. 


SA Superthick Metal Bond Discs


The SA Superthick Metal bond discs are suitable for grinding concrete, as well as terrazzo, stone, self-leveling and overlay floors. The unique metal bond of the SA superthick discs offers a very smooth scratch pattern and long diamond life. The SA metal bond discs are offered in 3-inch and 4-inch sizes, with standard velcro backing for wet use only; Also offered in 3-inch size with QuickChange metal attachment - these can be used wet and dry. Grit range: 30, 46, 70, 120.


Cementina Metal Bond Discs


Another option for grinding hard concrete is using the Cementina metal bond discs.  For soft concrete/terrazzo grinding, we recommend the special Cementina terrazzo bond.  Cementina grinding discs are best suited for lightweight machines, such as LAVINA 16 and LAVINA 20.  Cementina achieves a very smooth and uniform finish, preparing the floor for resin polishing steps, if desired. Recommended for wet applications only.


Brazed Pads for Lippage Removal


Superabrasive's brazed pads are recommended for lippage grinding, floor leveling, and thin coating removal and they perform excellent on concrete, natural, and engineered stone. 

These brazed pads are with velcro backing and should be used wet only. The Cementina brazed pads are offered in 3 and 4 inch sizes, in 30, 50, 100, 200 grit.
