SHEUTSAN 3.94 Inch Concrete Hole Saw, 100mm Premium Metal Hole Saw Cutter, SDS Plus Shank Hole Saw Drill Bit for Wall, Concrete, Brick, Stone, Cement

Heavy duty ,Impressed with performance

This worked well for me.

I'm extremely impressed with this bit, I needed to drill through reinforced concrete footing, I spent a total of 8h, although it was slow it got the job done and only ended up loosing one of the cutting edges. I've used "name brand" bits in the past and this one performed equally well.

These types of hole saws absolutely can't cut through concrete or structural brick. I spent over 1 hour drilling a single 4" hole through a single layer of brick. It couldn't even get all the way through, I had to use a hammer drill to make 40 small holes around the circumference of the hole and pound out the last 1/2" with a masonry chisel.

Went through my basement cinderblocks like butter and made quick work of relocating a dryer vent to a less optimal location. Excellent tool for the price.

I was hesitant at 1st but this product delivered. I had to install a 4" exhaust vent through 7" of concrete and I was able to do it with ease with this 4" concrete hole saw.

Did the job, but is not very durable and probably cant be used for more than a couple more times

I used this to drill through a block wall filled with concrete. I used a baush bull dog hammer drill and this thing made a perfect hole. Now after getting the hole started I removed the Pilot that causes that screw look like it was coming loose. The sets screw is the only flaw in this design. Just have to remember that you're trying to drill 4" hole in the concrete and you're not going to do that quickly. Be take your time and let the tool do the work you will get perfect results.

Lleva 10 perforaciones en concreto y sigue en buen estado, solo asegúrate de colocar una arandela de presión al tornillo que fija la broca piloto y apretar bien, con la vibración del sds se afloja y la broca quedará suelta con el riesgo de que la pierdas. En si ya se pagó sola con el uso que se le ha dado. El block hueco lo traspasa con relativa facilidad. Si lo que piensas pasar por estos orificios es tubería de 4", tendrás que ajustar ya sea el tubo o el oficio, ya que no pasará.

Muy bueno fácilita mucho el trabajo y realmente de muy buena calidad

es un producto fácil de usar ya que no cuesta trabajo ensamblarlo. se ve que esta hecho de un material resistente. el único detalle es que el seguro para sostener la broca es un tornillo y no algo mas seguro.a pesar de ese detalle cumple con lo prometido y te ahorra un buen de tiempo y estética al realizar un trabajo con la herramienta

Buu un en producto

Perforé una pared de hormigon para sacar el tubo de la secadora, quedó perfecto
