Should an Expensive Cordless Power Drill Break in Half After Falling From Four Feet Up?

So, this happened to my expensive drill gun after falling to the floor off a counter. Bummed, but hoping that Hitachi Power Tools will hook me up. Feel free to help by emailing them on my behalf. I only had the drill for about a year when this happened. It had never been mistreated and hadn't even been used that much, due to the fact that I wasn't teaching theatre last year.
