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

Use this bit in my woodworking projects.

I’m building a porch swing that needed about a hundred silicon bronze screws mounted flush with the oak surface. After messing around with an old B&D countersink bit with a collar that kept slipping, I ordered this bit. I’ve used Amana router bits with success and found this item to be no less impressive. It worked flawlessly to countersink to exact depth repeatedly. Expensive? Yes. Worth it? YES.

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.

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.

Very well built

Use this but one time and you wont ever be without it again - super easy and foolproof for countersinking screws

Nice clean cut on countersink, no discernable wobbling, and no marks. As a carpenter of 25+ years, I wish Id bought it long ago. The cheaper countersink bits either fall apart, are not depth adjustable, dont leave clean cuts, or leave marks. Those can be fine for occasional use, but I just finished a project with hundreds of holes and this bit was worth the investment.

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.

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.

I loved my Amana Tool - 55229 Carbide Tipped 82° Countersink with Adjustable Depth Stop, but only for a short while. Chalk it up to user error. What happened is the depth stop set screw flew out and the bit fell apart. I should have made sure it was tight and then checked it again after several uses. Unfortunately I lost the screw and in my anger threw out the whole bit. Oh well, live and learn. Im ordering another and this time Ill make sure its tight. The performance, for the short time I had it was typical with what youd expect from Amana Tools. Easy to set up and use, minimal marks left behind by the depth stop.
