In most cases it's actually cheaper to give you a new tool rather than repair an existing one. It's nothing for someone to grab a new one off the shelf and send it back and a lot easier than having someone trained to take it apart, replace or refurb anything that has issues, put it all back together and send it out. I think you'll find most, if not all of the major manufacturers do it this way, although they also do have repair staff on hand in case you want that specific tool back because of sentimental value or other reason.
