Appliance Repair Questions? Ask a Technician for Answers ASAP
Good morning, and welcome to the Technical section in JustAnswer. My name is ***** ***** I will help you today. There's no time pressure on this topic - it will stay open for many days, and you can reply at any time. I will be away from my desk sometimes, but will respond as soon as I can.There are different chuck keys, both in terms of the size of the plain round spigot that goes into the hole in the chuck, but also the pitch and angle of the teeth that engage with the chuck. Even if you bought the correct key for that drill, there's no guarantee that the chuck hasn't been replaced over the years. The best thing you can do it take the drill to a good tool shop and get a matching key from them.
B&Q sells some tools, but it's very much not a tool shop.
To suggest somewhere I would need to know roughly where you are in the UK.
Thank you for your rating.
