Review on 💡 SE 8257HDB Precision Twist Drill Gauges by Bryan Hill

These are quite small drills - the first one I broke before turning the drill on. It was my fault. At Ace, they're $3 for a single drill, and getting 10 for $4 (including shipping) is a great deal. I used them to drill 1400 small holes in 170 feet of 3/4 inch (200 psi) white pipe for my garden watering system. I've only used two of these - the one I broke and another. They worked fine.
