Review on 🔩 Stainless Steel Drill Bit Set - Imperial Standard in 64ths by Jason Mitts

The product was missing holes for measuring drills. I also tried calibrating 4-5 other bits but the holes wouldn't let a bit of the same size go in. It appears the gauge holes were punched out on a press resulting in small dents at each hole. Maybe that's why my drills couldn't be measured with a gauge.
