Query: Great drill, bad chuck

I love and hate this drill. The drill will take all kinds of hard drilling in tight places, but the chuck is sensitive to sawdust buildup and will jam unless a lot of care is taken cleaning after use. The chuck is also difficult to remove, compared to Porter Cable products for example. But when it works, it is great, like my Hitachi M12 router, which has gone strong for years!
