Re: Countersinking tips and tricks?
hello again after reading other replies in this thread, i started to think of this ... you may cut the chamfer :
... before driling, making also the spot for the drill ( attached is the classical hss spot drill )
... during drilling, using some chamfer adapters or a combitool
... after drilling :
...... by machinining, thus by changing the drill with a chamfer tool of you choice
...... by hand, by using a specific tool, which may vary in size from small ( like a pen ) to big ( like 400mm long, designed to be used with both hands, for chamfering big holes )
i have used all those ... i guess choice depends on real scenario / kindly
ps: in some conditions is possible to drill without using a spot drill
