New Carbide Countersink and Drill Stop for 10mm Teak Plugs

[sailorman]

I am about to refurbish the teak deck on my Oyster 406. There appears to be plenty (10-12mm) of teak left, but some screwheads are showing and the caulking needs redoing - I believe the deck is 20 years old. I have read the useful info here and seen the you tube videos - it looks straightforward, if time consuming and painful work. However, I have stalled before even starting - opinion seems to be that a Forstner bit is best for cleaning/deepening the screwholes, but the teak plugs are 8mm and I cannot find an 8mm Forstner bit anywhere. Any pointers on where to try (mail order as I am in Portugal), or what to use instead?

stanley counter bores { No 8 ) would have probably been used originally (snap off the pilot hole part &b re shape / repoint whats left ) )with matching plug cutter
