Kenyu 20mm Rotary Hammer Drill Machine KY-RH-20 with 3 pcs Drill bits

Powerful for its size and relatively light weight. Used it as jack hammer to remove tile and grout.

Excellent value for the money. Easily drill into concrete or remove a shower pan. Drill chuck is not the best but that’s not really a big deal.

I’ve never used one of these before, so I found the instructions extremely lacking. I was able to put it together well enough, and they provide you with some images and a bunch of text, but I couldn’t figure out how to remove the bolt after using it. I almost returned it because of this, thinking I had a broken one, because the instructions seem to indicate that you should be able to twist the bolt off. However, after some Googling of other hammer drills (because there were no videos for this model from other customers or from the manufacturer), I realized you have to pull back on the part that is holding the bit, in the area around where the handle is attached.Otherwise, great product for the price. I drilled through concrete block and also brick, and while I wouldn’t say it was “like butter” as some said, it definitely was very easy to use given a steady grip and applying a tiny amount of force.

Used this in my crawl space encapsulation project. Worked great, makes holes in cinder block like hot knife in butter. Not sure about long term longevity but was about the same price as renting one for a couple days. It’s a seldom used tool but seems better good for the price.

Works for what I needed it for and the price is extremely competitive.
