Amana Tool - 55229 Carbide Tipped 82° Countersink with Adjustable Depth Stop & No-

Use this bit in my woodworking projects.

The mechanism is high quality. The thrust bearing is a little cheap. As it ships, it (may) scuff your wood. This is easily fixed by placing painters tape before drilling. The tape adds enough friction to engage the thrust bearing. Problem solved. The friction bearing may loosen up in time. Aside from that minor problem, it works flawlessly. I would buy it again.

I had to counter sink some skateboard holes. This counter sink did the job. It’s build very well and it is very easy to use. I had a few small adjustments to get the right depth and it was easy. It left very nice clean holes in the wood. This counter sink it worth the money and its worth having in your tool collection.

Nice.

Works perfectly. New favorite go to countersink. The angles are good and it is quick and easy to use. If you are having marks after using it. 1. Use it a few times on scrap wood to get the bearing to open up a bit and smooth out. 2. I found you are best to go quick with the drilling. You need to have firm pressure and speed to have it stop the outer shell quickly.

Really great product when you are doing a repetitive set of countersinks and want to make sure everything looks consistent and professional. Great for adding plugs.

A bit pricey, but it does work, It functions as a depth stop. A valuable addition to your tool box for hard woods. you will have to adjust the way you use it on softwoods, simply because it is a softwood.

These seem to be all the rage, and the concept is fantastic. However, Ive bent two or 3 bits, even in the drill press. Im not sure what the issue is, as the bits seem to be bending near where the set screw retains the bit. Kind of disappointing, especially for the expensive price point

Very well built

If I could give this zero stars I would...bit broke off on the 4th hole I drilled. See photo and note the chipped carbide on countersink. Waste of $$$. EDIT: Thought about it, and decided the cheese-grade included drill bit was the real issue. Ordered another one, measured the bore with a minus pin gauge set, and determined it to be approximately .128. Figured the through hole bore on these countersinks will accept a #30 drill bit. A #30 is .1285, which is .0035 over a 1/8 drill bit. This tool is designed for #8 screws, which have a minor diameter of .123. So I got the stub-length (which is the same length as the supplied cheese-grade bit) #30 drill bits I also reviewed, inserted (snug fit, good for concentricity, which is what you want when counter-sinking!) into the Amana body and appear to be good to go. Spend a little extra $$$ on better drills and you may have a better result. I think the carbide chipped when the original drill bit broke off in my project. That still bothers me, but these are better designed than the vast majority of sleeve-type countersinks that inevitably wobble all over the place when you adjust depth. Three stars for design only, one star originally for cheap included drill bit. On the plus side, with clearance of less than .001 or so, the bits nice and tight in that bore and there is no perceptible wobble - even when adjusting the depth of your hole. Locks up tight as a bank vault.
