I've been a Plumbing Contractor for over 20 years. I've owned the 1675-1 model for over 15 years and I can attest to it's quality, durability, and longevity. I've abused my Hole Hawg...dropped it from rafters, dropped galvanized and black iron pipe on it, ran over it with my truck, etc....and any other way you could possibly think of abusing a tool on the job site. Never once has it failed to work or have I had to send it in for repairs. It has the power and torque to make short work in drilling holes through studs when roughing in new homes or used for repair and service work. The bottom line is...the Milwaukee Hole Hawg is the ABSOLUTE best and defacto standard drill for the plumbing trade. NO other manufacturer comes REMOTELY close to producing a drill of this caliber. PERIOD!!!
