Review on 🔧 Irwin Industrial Tools 10231CB 13 Steps: Quality, Durability, and Precision Combined! by Jimmy Bores

I used this drill to drill 6 1/2" holes in 1/4" mild steel and it drilled holes perfectly with no problems. ; The trick is to drill slowly, don't force the drill bit, just let it cut itself, and I used cutting fluid; That's why I rated it a 5 and it's made in the USA. I would recommend this drill to others. I also used a Neiko drill using the same technique as above and it was difficult to cut through 1/4" mild steel. I only drilled one hole and the drill burned out and couldn't drill more holes. I'm going to use it for 16 gauge sheet metal drilling, made in Taiwan.
