Review on 🛠️ Irwin Tools Step Drill Bit - 16 Inches (Model 10234) by Elvis Bragg

I build my own guitar effects pedals (pedal boxes) and this drill is a game changer. I no longer have to switch drill bits to drill the different hole sizes required for fabrication. One tip, though, is to use a TEKTON 6580 Auto Punch to start the holes and then use a 1/8" titanium drill bit to drill the pilot hole, otherwise this unibit tends to slip a bit. Also, lubricate the drill bit with Tap Magic Industrial Pro Cutting Fluid to greatly aid the process. I've drilled hundreds of holes in aluminum cases with it and it's still perfect. Good product. Will definitely buy again.
