Is there a knack for drilling a hole in plywood or am I using the wrong
type of drill. I need an 8mm dia hole and I am using progressively
larger HSS twist drills but the exit hole is ripping the final ply to
shreds.
Should I consider something like a auger or one og those flat drills,
if they are avialble in 8mm.
The exact size is not important as long as it is about 8mm dia.

One of these should be better than a regular twist bit
