Review on Shank Flutes Titanium Countersinks Drill by Michael Syph

dull blades won't cut wood or even plastic (instead of cutting, they just heat up and melt). horrible machining (on a household bench grinder with an inferior grindstone no larger than 6 inches). Shank and drill not centered. The images advertised are of a different (and better) bit. spend a few more euros and buy something useful.
