I'm glad I bought it. It arrived with a keyless chuck between fully open and closed so no problem. I've used it at least 40-50 times, alternating between 1/16" and 1/8" bits when drilling through metal. I've never had a problem with the keyless chuck. The price was right and the functionality was impeccable. Looks like I won. The one star reviews almost convinced me not to order this drill, but some of the 5 star reviews convinced me to give it a try. The reason I bought this and the reasons I almost didn't buy this keyless drill. .I have a 3/8" keyless cordless drill that I use most of the time, but due to the size of the project I need a corded drill from time to time. After trying two batteries and still not completing the project, I started looking for a cheap alternative. I also have a cordless 1/2" Milwaukee corded drill that I use with a keyless chuck from time to time. To keep the big round bits from spinning in the chuck I have to grip the chuck tightly, then to get the bits or big stirrer out of the drill I have to hold the chuck and hit hard in the opposite direction to what I normally do ends open at top with locked chuck. I can unlock it with an Allen key but it hurts. Given that and the one star reviews, I almost didn't buy this drill. So happy with the 5 star reviews that convinced me to give it a try. If there was a clutch it would be perfect.
