5-Piece 1/2” Masonry Drill Bits for Concrete Tiles Stone, 1/2 Inch Carbide Drill Bit Set for Glass Ceramic Brick Soft Metal Plastic and Wood, Hex Shank Drill Bit Set Diameter 12mm, Black

I had bad luck with a set of Bosch impact masonry drill bits. The DKIBBITH set has proven well-made and even the 1/8" drill did a good job in concrete, brick, and mortar. You won't be disappointed.

Bits worked as expected and seem to hold up well.

If you need to drill a hole in cinderblock these will work ok. Not the best masonry bits I have ever used. Made in China quality. I think they would break on any really hard stone. You really have to watch the RMPs when drilling with these or they will start to wobble and feel like they are going to break.

Super útiles y de muy buena calidad

Sales, delivery and price were excellent. I have not had a need to use the bits yet although they look good and the case to hold them is nice. We will see how they do. If I get about 6 or 7 hole out of a bit at this price I will be most satisfied.

They wear out a little quicker and are maybe not quite as good as the wood/metal/masonry specific bits, but they get through wood, metal and masonry as advertised! Probably best in masonry

As you can probably guess by the price and quantity here, these are not the best quality bits you’ll ever see, especially for the task of concrete drilling. But, if you are prepared for the fact that each might only be good for 2-3 holes, they are fine. I was able to easily finish my job with these and I had some left over. As long as they can put a hole in the masonry and not melt or start a fire from the friction, they are doing their job.

The bits can drive right through concrete very easily !! No hammer drill needed with these. I got about 2-3 holes out of each bit going in about 4"

Buena Calidad por el precio

Las brocas son muy atractivas, pero no pudieron perforar de manera correcta una pared de concreto. Estaré buscando otras brocas :-/

Comenzando por el envío, llego mal y rota la caja en que venían las brocas, las brocas no cortan lo que ofrecen y el filo, al hacer un solo agujero, por lo que sirven para hacer cuando mucho un solo barreno. producto de muy mala calidad. la verdad no lo recomiendo.
