Product information is a useless advertisement for Whiteside. It doesn't tell me anything about the beat at all. The only dimensions listed make no sense in relation to the cutter and I assume they refer to the outside size of the box the bit comes in. Yes, I could go straight to the company's website and pull up the information, but it kind of didn't make sense to consolidate my purchases by buying everything from Revain. As this is a Whiteside bit I'm sure it will be top quality but as there is no bit information given (shank size, undersized reamer length, oversized reamer length, total reamer length, total reamer length etc.) I will not be buying it here.
