I thought the bits were going to be garbage because of the price, so much so that I purchased 2 bits. Boy was I wrong. Drilled 6 - 3" holes in two days. The bit was slow on the second hole, I thought it was the bit dulling out but it was lack of water. Turned the water up and it was like a hot k ice through butter. 8 minutes to drill through 4" of fired brick. Awesome drill bits.

muito bom para a Qualidade e preço

Good value for the price. I only used it twice to make holes for radon gas pipe. Perfect fit for a coupling fitting of radonx 4 inch pipe. One hole in the basement floor of just under 4 inches thick. One hole in a concrete block wall 10 inches thick.

Super Preis Leistung. Günstiger als jede Anmieteung im Baumarkt.

I’ve purchased this tool to install a mini split AC system in my garage through a block and concrete wall, although the work was done, I ran into some difficulties with the pilot bit, the adapter I used was the SDS-plus and the pilot drill bit to do a pilot hole through the wall, the bit is attached to the adapter with a side screw that lands on a flat side of the bit, the problem was that with the vibration the securing fastener always came loose no mater how tight I tried to secure it, I ended up using a different drill to make the pilot hole and once assembled together with the barrel was a little better but still managed to get loose several times, if the drill bit came with a notch for the securing fastener to land instead of a flat surface probably there is a better chance of keeping in together. Overall, got the job done with some hiccups

It does the job. I drilled a clean hole through 2-3 inches of brick to feed my hose through the wall. Maybe it was user error, but with the guiding pilot bit in, the main core just wobbled around way too much to bite into the brick. So what I did was cut out a small hole in a piece of plywood, then anchored that into place and used it as a guide. No issues after that, it just took a while. The hole was very clean. I then threw a pipe and 3D printed an escutcheon.

C’est très bien, je suis content

I bought 5 inch, but the actual diameter was 4.5. I don't know why. I drilled 2 holes in foundation strip with deep 22 inches.

Gute Verarbeitung ist leider nur mit geringer Geschwindigkeit zu verwenden da Sie stark Vibriert
