I was arguing between this model and RH328VC, I chose this model because it has 40% more impact energy (important for such a tool) and also more metal on the front of the case compared to RH328 (RH328 has plastic) . I'm careful with my tools, but I certainly use them extensively, so I need a professional-quality hole punch, not the Chinese consumer models that big stores sell. For anyone wondering, the hammer/hammer drill bits at Home Depot/Lowes don't even compare to high end Bosch drill bitsβ¦
