      I use the same set-up as Daryn for re-pivoting. These carbide drill bits make it so easy and with daryns oil system I have not broken a bit for ages.
      You will be amazed how easily they cut bernie :)

        Nice find Bernie!
        When using carbide drills I tend to more or less double the rpm over HSS drill bits. This really helps cut down on carbide chipping for me. Also some type of clutching mech. like what Darin and Paul use is very helpful…even when using HSS or homemade high carbon spade drills. Will save your butt many times over!

        Enjoy!

          Thanks Bob. One thing I have found (right or wrong) is that if I put the drill bit in a collet and don’t tighten it down tight it will let the drill turn in the collet if it catches. Not sure if it is similar to Daryn’s system but I sure haven’t broke a drill bit for many years.
