Economy PCD Segments on Quick Change Holder for Concrete Polishing

PCD (Polycrystalline Diamond) tools are designed for coating removal.  Recommended rpm: 550-650. They are direction-specific, so always check the rotation direction of the grinding heads. All Lavina ELECTRIC grinders WITH THE EXCEPTION OF 32″ ELITE models require standard right-hand rotation tools (black pcds). All Lavina PROPANE grinders and 32″ electric Elite models require PCD tools with LEFT-hand rotation (blue pcds). 

PCD tools WITHOUT Sacrificial bars or Metal Bond Button are the most aggressive style and will leave a very coarse profile on the concrete underneath.

These are suitable for removal of:

• Thick mastics and glues, and thick elastomeric membranes
• ¼” Thick Parking Deck Membranes
• 30 mils and up epoxy coatings, and any coating with silica sand broadcast mixed in

PCD tools WITH Sacrificial bars or Metal Bond Button are designed to remove coatings over a surface equal to a troweled surface and will not damage the concrete. The sacrificial bars or the metal button act as a stabilizer and depth guide, and reduce the gauging of the floor caused by the aggressive pcd segments.

These tools are suitable for removal of:

• Medium to thin mastics or glues
• Failing epoxy coatings (30 mils or less)
