People who do DIY as a hobby probably don't use a chuck key, but contractors and professionals who use machinery on a regular basis will definitely use this tool. It's used to tighten and loosen gear systems in machinery, and while they do the job, they're often incredibly hard to use. That's because their handles are often incredibly small and fiddly. But what if we told you that they don't have to be?
It's super easy to use some wood to make your chuck key longer, as you just need to make sure that the original key fits snuggly into a hole you drill into the wood.
