This: STEP DRILL BIT 1/4 TO 1-3/8" TITANIUM BITS TOOLS - eBay (item 250404606464 end time Apr-12-09 20:34:11 PDT)
goes up to 1 3/8", which is plenty large enough for the tubes used in the CTH.
In fact, it's just the right size to use a ring from a tube protector to "finish" it up, like the last pic here:
