Works pretty well, the depth stop does leave a mark that needs cleaning up afterwards.

These are very good countersinks if you want repeatability and no marring of your wood. The bit drills cleanly, same for the countersink and the depth stop stops spinning when you make contact with the board so you don't leave any marks. Overall I'm very happy but I have a few things you should be aware of: 1. The drill bit is not really adjustable. It is technically adjustable but the travel is barely anything. If you require a long pilot hole I'd suggest swapping the stock bit out for a longer one as the stock bit is only 1 13/16 long. That said, unless your screws are really long it's enough predrilling for most applications. 2. This is the most import point - go the the Amana web site and review the size difference for each model. Amana offers multiple models PER screw size. There's standard drill bit for softwoods, standard drill bit for hardwood, tapered drill bit for softwood, and tapered drill bit for hardwoods. So you might find different countersinks that all say there are for a #8 screw but they all have different diameter drill bits. Also, Amana's descriptions aren't always that great which doesn't help. For me, I'm using this mostly in plywood, MDF and softwood so a straight 7/64 bit is the right one for #8 screws (55241). Do your research and make sure you're getting the right countersink because they are expensive bits. See below for an example: 55153 - tapered bit, 5/32, #8 softwood 55241 - straight bit, 7/64, #8 softwood 55193 - straight bit, 1/8, #8 hardwood AND #10 in softwood 3. While not a deal breaker, the included double ended Allen key needed filing on the smaller end to fit the hex nut as the key was not machined well. It was fixed in a minute or so with only light filing on all sides but I shouldn't have had to do any.

Un poco desilusionado, esperaba más de esta marca. Deja marcas en la madera y puede arruinar el trabajo por completo
