NORTH GRAFTON, MA - Creating the proper surface profile is important for many blasting applications. Washington Mills has created an interactive surface-finishing guide to assist customers in selecting the correct grit size of BLASTITE for their surface-finishing applications.

The guide provides a suggested grit size that is relative to the Ra value based on a specific work piece, nozzle and PSI. The Ra value (roughness average) is an established method of quantifying the surface finish on a work piece.
