The hammer drill from Makita is actually a well thought out work unit. With the right drills it is every handyman make a lot of joy. Unfortunately, one must obviously treat the auxiliary handle with depth stop very carefully. For me it is simply canceled when tightening. A light gray plastic components in its interior was simply sheared off, although I'm not Schwarzenegger. I never would have expected. Incorrect design or material choice, I would say. So far I was from the expensive Makita products very confident shame.
