Not. Terribly bad performance.

The toughest countersink ever. Red and uneven. Cut out pieces of wood instead of drilling a plain hole for a screw. Shocked at how bad it is.

Pros
  • Easy to use
Cons
  • Quick start guide

You'll need them in your woodworking toolbox

You may think all you need is a countersink with a router in the middle, but I think you're wrong. They are very useful for enlarging existing holes, starting holes that need to be very small or very thin. A thousand times they succeeded in their task and others did not. Every toolbox should have a set of these. They work with aluminum, although too much aluminum can dull them. It is great! My only complaint is that they are easy to lose. LAUGH OUT LOUD

Pros
  • Confident
Cons
  • Out of fashion

Extremely poor performance

The first one I used in aluminum was a little off center but it wasn't terrible so I figured this set would make a decent cheap backup set. Today I used two others and they were absolutely awful. Extremely non-concentric and vibrates horribly when used in a drill press. For those who don't know, concentricity is basically evenness with respect to the central axis. In other words, as the tool rotates, the tool and all cutting surfaces maintain consistent contact with the workpiece, minimizing…

Pros
  • Easy to read control panel
Cons
  • There are new competitors
