I need to install some Blum hinges that require drilling a 35mm hole in some cabinet doors, but I don't have a drill press. I've noticed that the warnings on most 35mm forstner bits say to only use the bit in a press or with a drill guide attached to a hand drill. I also don't have a drill guide (and don't want to buy one since I will probably spring for a drill press sometime in the late summer or fall this year). Can somebody tell me how dangerous it is to use a forstner bit in a hand drill? Is it a safety issue or simply an issue of the resulting quality? (These cabinets are just garage storage cabinets, so quality isn't my #1 concern in this case.)
