Review on 🔧 CORTOOL Titanium Unibit 3-Piece Change Set by Tommy Penn

No points for my stupidity but be careful with that. They are sharp and good for drilling holes in sheet metal. There's no easier way, and with a hex shank they stay in place for rated action in heavy metal. I threw one into the drill press at low speed, thinking I could hold the thin stainless steel plate while I made the 5/8" hole. As the 5/8 nut gripped, he twisted the metal in my hands and cut nine stitches. Visiting the emergency room with both hands through a couple of fingers. Trying to drill through hard metal without ferrules or gloves is entirely my fault. So be careful, especially at 3/4. He has more influence than you.
