    Re: Ductile Iron

    Yikes, that is a tough one. The best option I can think of is a 4mm Width Stub Grooving Insert that is either Cermet or Ceramic (the Harder Cermet or Ceramic Substrate will give a much better finish...

    Re: Deep drilling holes at 6000 rpm.

    The key thing in deep hole drilling is matching the drill point from the Spot to your Drill. Would you know the drill point angle of your 1/16" Drill Bit? Most HSS Drills are a 118 or 130 degree...

    Re: Breaking Small Drill Bits in 7075

    Craig is correct on this, the main issue is the chips are not evacuating causing the flutes to clog up and the drill to break. If you take 0.5XD Pecks then you should solve the issue. Here is what...

    Re: Is there a 10mm collett for an er11 nut?

    A 10mm Collet does not exist for an ER11 Holder, the ER11 collets go up to 7mm (.2756"). To get to a 10mm you would need a ER16 Collet. The 6mm Shank Bit would be the way to go for you unless you...

    Re: Drilling 3/8 x 3 inch deep holes in 6061

    It does sound like the chips aren't evacuating causing the drill to load up/shriek and then walk. There are a couple ways to fix this:
