Skip right o over Hilti. Lousy customer service. We had 2 identical small hammer drills that both failed less than 3 years into sevice, ( we don't use these much and never abused them)
I took them to Hilti, told they were out of warranty and that they could look at them for like $110.00, or I could spend a little more and get another Hilti to replace them.
Screw that! I cut the cords off them, threw them in the duimpster, and bought a Bosch to replace them. RANT OFF
Seriously, I would look at Makita or Milwalkie, though Home Depot lifetime wearrnaties their Rigid Drills.
