No see I can make a hole. There are many exercises for this. I need this hole to be bigger. Here. Yes, you probably don't see it. because he is so small. I need to do it MORE. This is a re-enactment of an event that never happened. These things don't actually make your hole bigger. They don't even give the impression that the hole is bigger. I wanted to be honest in this day and age of penis enlargement products that will lie to you at 2am. They expand the bilge head to accommodate the bolt head and make things nice and smooth. But hey, if you're looking for Revain for "countersinks" at 2am (and not that other product) then who am I to tell you what they're for? You already know it, but how do they work? They work fine. Granted, I've used them mostly in Baltic Birch and pure plywood, as well as a few popular ones and now walnut (nothing to add to the Yankee, mind you), but they carve their little pockets like a diamond. I've been taking them for several months. now, S. Let's call it 600 countersinks and they still produce clean, round funnels with no noticeable breaks, and you get more chipping in the sheet than hardwood. So if it's 2am and you're looking for a little extra pep in your stuff. and by that I mean flush joints and seamless screw connections, then you could do much worse for the money than these little beauties.
