Review on 💎 Precision 0.8mm Jewelry Keychain for Optimal Casting by Matthew Miles

Bits will fall between the jaws. They don't tighten down the center of the cartridge, rendering it unusable. I really wanted it to work. I'm not a beginner carpenter. I have over 50 years of experience as a master carpenter and ship builder. I may have a defective one, but I don't want to risk replacing it with the same piece. I'll look elsewhere and so will you.
