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!

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

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