PCDS are best suited for removal of coating thicker than 3mm like glue, epoxy, mastic, urethane, black bitumen paint, paint, adhesives.

Manufactured with premium grade polycrystalline diamonds, CDs are unmatched in the coating removal industry. They are ideal for removing thicker pressure-sensitive coatings over 3mm thick such as glue, epoxy, mastic, black bitumen paint, paint and adhesives. PCDs are more aggressive and longer-lasting than standard diamond cup wheels, as metal bonds can glaze up easily on thicker coatings. This tool’s scraping action eliminates gumming up of the segments and maximises production. PCDs will leave a rougher finish but are the ideal first step for removing approximately 50% of the coating beforeusing a metal bond segment to remove the rest. Even though this involves 2 steps, the coating is removed a lot quicker. As PCDs can badly gouge the floor, especially ifthe operator is inexperienced, Syntec offers parts with stabilising buffer segments that reduce the depth of the cut and prevent the PCD from digging in too much.
Depending on the material and finish you are looking to achieve, different segment types and shapes are best used.

As a general rule of thumb, a) the more segments a tool has, the smoother the finish and the less aggressive it is, due to more surface area and less weight on each segment and b) the smaller the segment, the more downforce and the more pressure you’ll get out of the machine and also the more aggressive the segment will be, meaning it will wear out sooner.
