501080-HP 80 Grit Puck

This 80 grit, 4 seg metal bond diamond puck is for use with National’s largest concrete grinders; the GP500, GP700, and GP3000.  Counter-rotational grinders are for large spaces and high productivity rates.  The 501080 is part of our series of concrete preparation diamonds in a hard bond.  

This diamond grinding puck is often ordered with the 501025-HP, and the 501040-HP. Together, this series of diamonds is used for prepping concrete floors for topical coatings, overlayments, and adhesive. 

To test your concrete hardness prior to prepping with these diamonds, use the 8270 concrete hardness tester. Additional methods for testing concrete hardness are detailed in this video.
