For sale is a HEINRICH? Cross-Hole Drill Jig "PUMP LOCK" FIXTURE GREAT CONDITION! I AM PRETTY SURE THIS IS A HEINRICH,IT HAS TO DATE BACK TO THE 70'S, I USED ONE BACK IN MY APPRENTICE DAY'S. It is missing a lower v block, this can easily be made. This Tool Uses Removable Drill Bushings available from MSC/McMASTER CARR AND OTHERS THIS FIXTURE IS USE TO CROSS DRILL HOLES IN SHAFTS, ONE OF THE MANY APPLICATIONS WOULD BE FOR MAKING BOLTS FOR SAFETY WIRING.
