Review on Hakkin Jewelry Drilling Electronic Assembling by Charles Palma

Works as expected. A pretty decent set for the price. Used half a dozen times on epoxy parts and works great. The drill holds the bits very securely. Keep the hand pressure constant but not too strong. A small tan line cracked on first use. All my fault. Learning curve I hadn't used either of these prior to this purchase. I pressed too hard on the microbit. I would give it 5 stars if the micro bits were made of something more durable and if there was a grip pad to absorb shock and relieve hand fatigue. The mini vise also works great for my purposes.
