Diamatic® has designed ULTRACUT™; a joint clean-out blade embedded with a diamond matrix on all sides of the cutting blade that will achieve optimum clean-out & cutting blade performance. 

Conventional concrete saw blades made for cutting concrete have diamond segments adhered only on two sides of the blades and are not made for cleaning the sidewalls of the joints efficiently, when in fact they can miss up to 40% of the side walls while packing the pores with dust and debris. 

ULTRACUT'S engineered design creates a vortex that efficiently pulls debris from the pores and removes hard joint sealant material from each side of the joint’s side wall producing a clean, sound abraded surface for the joint filler to adhere to. 

Never underestimate proper joint preparation; poor surface prep can lead to quicker failure from disbondment.
