[sdiy] what size countersink?

[Danjel van Tijn]

Hi Cary,

Thanks for the info. I intend to buy a proper countrsink bit (one that
is meant for 82degree) but wanted to know how wide the bit should be?
There are several sizes and I guess I wasn't sure if this was
important. i.e. If you get a countersink that is 0.5"wide bit but it
is still 82degree angle it should not matter that it is so big (since
you are only using a small section of it's tip).

I was thinking this may be good:

But I can get ones that are larger and smaller as well.


cheers,
Danjel
