Hmmmm ?
No doubt a great drill but in hard working apps such as brand new sharp drill bits drill in steel and get caught up it stops making it very hard and longer to push the bit through. Good luck

great tool, but it's got some draw backs
I'm in general aviation so I prefer a high rpm, good trigger modulation and light weight/compact. I love this drill, however if you plan to use this drill for a lot of low torque fasteners as I do then you'll find the electronic clutch inferior to a mechanical one and the slow start at lower clutch settings extremely annoying. Also the chuck will spin the whole drive train before you can get a proper clamping force on the bit. Again I'm I general aviation so 90% of the work I ask this drill is a 1/8th inch drill bit in 2117-T4 aluminum. For my work it's great when you have a lot of rivets to drill as I frequently do. But any work that you rely on the clutch, get the older model with a mechanical clutch. I use a bosh ps22 for inspection panel fasteners and the Milwaukee for drilling rivets on all the sheet metal repairs that as an employee of a flight, school is often.

Describe Yourself:
Gr8 Tool, I am a DIYER and I got the same results as my 18v
Quick review : Views from an active DIYer I love the hammer drill , everything that I was able to do with my 18v tools. I got accomplished with the 12v little brothers. Having lightweight tools reduces the load and strain and is sure to add longevity to your work life. More In depth review: Hammer Drill: To switch the Drill/Drive mode you have to rotate the collar past 16, there are rubber molding by the hammer icon on the sides I initially thought that was how you switch the modes, by pressing it. That was not the case. For my needs the Hammer drill worked well. I used it with landscape timber, 2x and I had no problems at all. You can adjust the torque settings and when it reaches its maximum torque you can hear it powering down and it stop altogether. You have to release the trigger and press it again if you want to continue. This is good to ensure you do not over tighten a screw

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
