This drill bit is too long for very small holes. It cannot drill half-inch holes, 2 inches deep means 2 minutes of drilling. This thing struggles to drill 3/16 faucet holes. I will contact Makita to see if I can trade it for something else. DO NOT BUY if this is not for the home. It can't really be used. The rest of the small car line is great so this was a big disappointment. I've waited 3 months to write a review and this is not the first impression.
