CRL Resin Bond Blades use a softer bond to allow for the fine grit sizes recommended for use in chop saws and precision equipment. Resin Bond Diamond Blades offer the best finish, less chipping, and can eliminate secondary grinding applications. With a full 9/32" (7.1 mm) diamond depth, resin bond blades are more forgiving than other blades. Use with straight water to cool. Also available in different diameters, grits, concentrations and arbor sizes. 50 concentration provides best finish at a slower cutting rate and sorter blade life, compared to 75 concentration, which cuts faster.
