305 HOLLOW DRILL BITS

William B Rudow, Inc Hollow Drills are manufactured with a special alloy of the finest steels: chromium, vanadium, and molybdenum.  They resist wear, stay sharp longer and won’t clog, chip or twist.  The razor sharp cutting edges are carefully machined to precise tolerances.  Every Rudow Hollow Drill is thoroughly inspected before it leaves our factory.

OUR PAPER DRILLS ARE GUARANTEED AGAINST BREAKAGE – HOWEVER, NOT AGAINST FAULTY USE.
