Splitting back side of wood with Brad point bid...

[charlese]

When drilling my pen blanks, I use a vise with two pieces of wood with V's cut in them that support the wood down to the bottom which sits on a 3rd piece of wood. I still infrequently get some breakage with some acrylics. So, in the future, I will cut the blank longer than necessary and knot try to drill all the way through - just far enough for the tube ( and a little longer) and will then cut to near final size.

Makes sense to me!:)
