Q1. What diamond blade is recommended for multi-blade pavement grooving?
A. The DIATOP MGB403210 Multi Grooving Blade is designed for professional multi-blade grooving applications on highways and airport runways. It features a 400 mm diameter, 3.2 mm segment thickness, 10 mm segment height, and 75 mm arbor with 5 pin holes.
Q2. Can the MGB403210 be used for highway and airport runway grooving?
A. Yes. DIATOP Multi Grooving Blades are designed for creating repeated grooves on highways and airport runways using multiple blades installed together in a controlled configuration.
Q3. Why is arbor configuration important for the MGB403210?
A. In multi-blade grooving, the arbor and mounting configuration must match the grooving equipment. The MGB403210 uses a 75 mm arbor with 5 pin holes and should be selected according to the machine setup and required groove configuration.
