Review on 🔧 Unleash Your Precision with Century Drill Tool 11431 Gauge: A Must-Have for Every Handyman by Leo Fairchild

I can only tell you about my experience with this bit but it has a lot of wear. After drilling a hole that was out of spec (too big) I looked carefully to make sure I wasn't inserting it incorrectly into the chuck. I remeasured the part setup on the drill press. I turned on the drill press and just looked and you could see the wobble. I took out the racquet and placed it on a known flat surface and you could see the flex. I double checked some of the Bosch & DeWalt bits I have and they came out perfectly flat. I didn't bother with my dial gauge, it wasn't worth the time. If you want an accurate beat, then this isn't it. If all you need is a hole this size, it will do the trick. But I will not buy this brand again.
