Review on 🔩 Amana 55264 Quick Countersink Diameter by Colin Watkins

I have used many different countersinks over the years and Amana has always been the best by far. The two carbide blades cut cleanly through every material I've used them on: hardwoods like maple and oak, softwoods, melamine and more. If you drill a lot of pilot holes, this is the BEST drill bit. The cutter version also works great in a drill press.
