Perfect countersinks every time using the adjustable depth stop No-Mar Countersink bit. This is one of the most used tools in my shop because of the clean cut it leaves at the right depth for every single countersink without marring the surface of the material! Shown here is the version that is for Festool CENTROTECH system, but I have also listed the standard hex shank version below as well. All tools used in this video are available from @toolstoday, be sure to check them out on our website! -
