Review: Excellent value for home user - As a first time sds user am impressed with the power of sds bits to penetrate concrete compared to a regular cordless hammer drill with chuck. The possible drawback of not accepting regular bits can be overcome by getting an sds drill chuck adapter for non hammer use only. Could drill about 10 1/2"x6"deep holes in hammer drill mode before the battery was down to 50% or 2 out 4 LEDs. This is probably when I am ready for a break. The charger shows a red light when charging, green steady when charged, and green blinking when battery is removed. The battery 4 bar led is a nice indicator of remaining charge. Like almost all tool brands this uses a unique style of battery. It would be an advantage if you could interchange batteries. After using this for over a year, it's been a good if somewhat heavy tool. It offers a 3 or 5 year warranty to consumers if you register.
Review: Powerful drill - I was a little nervous purchasing this drill, but for the price I figured I would give it a try. I can say that I have been pleasantly surprised with the power of this drill. I have used other hammer drills in the past when drilling holes in concrete block that dont have near the power that this drill has. With the hammer drill setting on it goes through concrete block like butter. I have been using this to drill holes to put up hurricane panels and it has made the jobe so much easier. I would definitely buy this again.

### ⭐⭐⭐⭐ Occasional use
*by S***T on November 2, 2024*

It is a nice quality product. The only thing is that it is too light for my use, The battery depleted pretty quick and it takes a little north of two hours to fully charge it again. If you intend to use it on an occasional basis, go ahead and purchase this, it is perfect. If you are like me, Contractor either purchase another battery or go with a corded product
