Hello,
Is there any website that serve as guide to ratios between the endmill and shank diameter? A small company where I work received a request from a client for a carbide tipped stub length drill. The issue I find however is that shank diameter is only 3/8 while the rest of the endmill is 55/64. It seems to me that shank diameter is too small and ideally I would like to recommend a viable alternative to their request. Any suggestion is greatly appreciated. Thank you.
