Review on 🔩 Irwin Industrial Tools 3046011 Triple-Cut Drill Bit by Joe Garczynski

Purchased as a stock deal. The only apparent reason for the discount was crumpled packaging. The bit comes with a replaceable Central screw supplied. Easy and quick drilling in double material. Better management than I expected. I encountered a nail that I could have drilled with a little more effort but decided not to risk it. The nail was reduced by half, without damaging the drill and after removal the nail continued to drill with no problem.The cutting edges are so pronounced that even if some damage was found it could be repaired with a grinding wheel on a Dremelt.I don't think the cutting edges could be repaired with a Files could be effectively sharpened as the space available to run the file at the correct angle is limited . A bit pricey for my budget but for a DWV project where the time saving compared to using a traditional cork hole cutter was worth the cost. Will soon be looking for the next size up for my 2" pipes.
