the make special drill bits for predilling and counter sinking so you can do countersinking and predrilling both with one bit. Got to like a lowes or home depot as they have them. They will say what diameter screw they are for like a #6 or a #8 size screw. Just ask someone there and they will show you exactly what you need as long as you know the screw diameter. They cost around $5.

FYI - I usually like to use a #8 or a #10 size screw depending on what size of box i am making. For the 1 and 1/2 or smaller length screw i will use a #8 but for 1 3/4 and bigger i will use a #10.

^^link doesn't work.

I use a normal bit for drilling and countersinking, just back the bit out a little, and make circles to widen out the top of the hole. Probably not as easy as a countersinking bit, but it works.

1/8" drill bit, 1/2" countersink

just match one with the shaft of the screw, then set your drill to reverse and let it shave it off. Works like a charm :D

i personally like the above because it has everything in one that way you don't have to mess with two different bits. Simplifies everything, but that is just me.

i bought one today and i like it alot, mine is a #6 hitachi and the length is adjustable and the bit can be replace.......not to say that the others don't have these feature, but this is the only type I found, cost about 5 Bucks.
