First I bought an arbor press for DW so it could write on leather. But the handle was so short that there wasn't enough leverage. I used this drill bit with more cutting fluid to enlarge the gear hole for a bigger grip. The cut was clean, the drill did not chip or dull. For the arbor press I bought a 24" HFT pry bar and cut off the swivel head. The shank fits the pinion perfectly and now has double the leverage. Great nozzle for the price. decent square storage tube Excellent overall.
