Sweet Tips - 1/4″ hex shank countersinks are fine for a quick drill. They don’t slip in drill chucks. You can make deep countersinks easily by setting the countersink’s depth stop to allow the countersink to drill more deeply into the work surface. Be sure to measure the size of your plug to be sure your countersink’s body will make the right-size hole.
