Review on 🪒 Irwin Tools 16" Step Drill Bit 10232 by Mark Sharma

I used these bits when installing whiteboards and projectors in schools to make money. I used them to cut holes in the stand that connects the ceiling mount to the projector mount as I often had to cut the stand and lost the factory mounting hole on one end. I've found them to be the quickest way to drill round and square tubing in thin wall metal (<4mm) on site, leaving a clean round hole with little to no burr. They are also good for drilling plastic when the need arises. . This Unibit is accurate and true to my home use requirements. I have used it to make exercise equipment at home and enlarge existing holes. I give this product 5 stars.
