Bought this item in July and when it came time to used it I discovered that the center drill was too short to to drill a starting hole. Other than that, it performed exactly as was indicated and I would recommend to others.

Works Great!

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.

Cumplió su cometido que fue realizar un agujero sobre una placa de hormigón prefabricado en una pared de una nave industrial.
