Review on 🔪 Irwin Industrial Tools 3046009 3 Cutter: The Ultimate Tool for Precision Cutting by Logan Collier

I have used this bit to drill deep holes in pressure treated wood. It worked very well. The cutting action is aggressive but still leaves a relatively clean hole. I used both a drill and a hand rest to drill the holes. When using a drill press, I found that removing the center screw from the drill slightly reduced aggressiveness and made the cut more precise/smooth. When using the hand stop I found that resetting the drive screw into the bit improved the cutting action. So being able to insert or remove the center screw was a useful feature.
