Drill best for use but price in amazon too hight because whenever i live i want to get in 5800/- k And in amazon price 11k how

Very bad

So far, I have only used this to drill small holes in concrete paving blocks (16x8x2) to install screws to hold down a storage building. It worked great. It seems very sturdy. I have a chain saw from the same company (which I like a lot) and it uses the same batteries, which is nice. This is my first time to use this type of device, but it worked very well for me, and the price was very good.

Runs like a champ. Pounds rebar into degenerate granite. Breaks up cement. Powerful. Batteries are big. Instead of calling China our enemy maybe our politicians should study what China is doing right. Singapore is their model. This company makes a lot of other brands as well. From the battery it looks like they might be making Milwaukee tools.

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.

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

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.
