I just opened up my first Amana drill bit with an 11/32" bit and it vanished into thin air. I was in my own kitchen anyway, I wanted one because it came with the RIGHT bit (11/32 inch) but for $33 I just didn't feel it. This one costs $15 and the quality is TOP SHELF. The two locking hex plugs should last a lifetime as they are strong and seemingly sturdy. These carbides are for meticulous carpenters who take the time to do quality work. If you are in a high-performance environment and you are making toenail bits, you will end up breaking the bit, which will break some of the carbide. In this case it will be scrapped. I don't have it and I don't let anyone use it. But my buddy let the kid use it, and sure enough, the clicking: the drill bit and both carbides broke. Creating a perfect burr-free countersink. Don't waste it on chipboard/chipboard or MDF. Don't even think about banging it on aluminum or stainless steel. However, you can drown in aluminum laminate, but not in its blocks - it will be BROKEN. You need a flute for this, which is great too. This is the ONLY way to dive into aluminum stocks. If you REALLY need to dive into a stainless steel laminate, make sure the feed rate is slow and steady and the drill speed doesn't exceed 200 rpm. Stainless steel gets very hot very quickly and can shed sharp edges, but I did that too. The shank is a standard 1/4" hex quick release and speeds up the job since most of the other parts you just pulled out of the drill were also 1/4" sizes. The supplied drill is also of the best quality. Anyone caught putting this in a bludgeon should be treated brutally! This was a rating of Beer 1.
