Schnelle Lieferung! Super Produkt. Gute Verarbeitung und hält was es verspricht in der Beschreibung!

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.

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.

Valutazione ottima ma non eccellente. Da migliorare la punta di centraggio che dovrebbe essere più rigida per iniziare il foro con più precisione, perché a causa della rotazione tende a ruotare più ampiamente rispetto al fulcro. La qualità della tazza è buona. Provato sui forati.

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