I don't normally leave reviews, but this thing surprised me so I had to. Its low cost made me worried about the quality, but it managed to get through my poured wall foundation with ease. Use water and go slow.

I almost rented an SDS Max and 2" core bit from HD which would have been $157 for the four hour minimum. I own the SDS Plus 8 amp corded so I opted for trying this to save Ma money for her new water lines through 8" of 1960's concrete basement wall. I was drilling about 6' high from the inside out and my biggest concern was hitting rebar. That was the biggest concern until I started drilling. I did everything I could to mitigate hitting rebar using strong magnets, stud finders, measurements from known rebar locations, etc.. I calculated as best as I could and that part paid off because I didn't hit any rebar. However, I spent a total of about 30 minutes drill time getting it punched through because of the jokers who used inch and a half aggregate in the concrete mix. The bit did its job and still looks really good for what I expected. The bigger aggregate made me work harder and when I wasn't fighting getting through a mini-boulder it made dust and would eat almost an inch a minute. I only had 3 mini-boulders and 2 were at the same time which is what really slowed the progress. The bit slowed down on the larger rocks and I had to be patient and let it cut its way through, but it still cut smooth even when it was gnawing its way through them. I was expecting to affirm or deny its ability to handle rebar, but fortunately I was unable to provide such information. Overall pleasantly surprised and happy with the price and quality. Saved $$ and time overall. Plus, I now own a 2 inch core bit if I ever need one again.

Buen producto

Llego en tiempo y forma, gracias. Por primera vez uso esta herramienta (SALI - Broca saca bocado de diamante SDS de 1 pulgada de diámetro x 10 pulgadas de largo) y debo admitir que al principio me vi como un principiante... de hecho lo soy. Pero al recordar algunos videos, donde recomiendan como usarla, al final, fue pan comido. La estrené junto con un rotomartillo SDS que compre aquí en Amazon. Desde luego hay brocas de mas calidad pero, SALI funciono tal como lo esperaba.
