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

I build a lot of painted desks out of MDF and securing them with brads and screws are just the quickest assembly process. But its always been such a pain to work quick but ensure that I dont countersink the screw hole too deep, because then it takes too much work and time to fill, dry, sand, possibly fill again, and repeat. At least on MDF, the no marring feature worked perfectly and setting the countersink to only leave 1/16 of depth when the screw is fully seated is perfect. I can now countersink everything quickly and be sure that Im hitting the perfect depth. Will buy some more of these for the #8 screw as well.

I’m so happy with the purchase, easy to use!

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’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.

Exelente, I use this bit tomake 1500 holes in hardwood, brazilian cherry and cumaru and still works like new, still sharp

Very well built

Use this bit in my woodworking projects.

This makes beautiful, repeatable countersinks.

This tool makes counter sinking screws completely controllable. Have it sit a bit proud? No problem! Flush set! Easy to do! Countersunk slightly, or deeply is not a problem. Pre-set it and go make multiple screws, set the way you want it!

Very clean cutting and collar does not mar surfaces. Used it on pre-finished maple plywood and performed flawlessly.
