10-Piece Masonry Drill Bit Set for Concrete Tile Glass Ceramic Brick,1/8 to 1/2 Inch Drilling Bits with Triangle Handle,Tungsten Steel Alloy Tip.（Black）

Some tile is HARD to drill through. I needed to install shower safety bars and neither my regular drill bits nor my carbide masonry bits could make a hole. I decided to try this set and I'm glad I did! I used the smallest bit first to drill the (12) pilot holes. I drilled at a very low speed, dipping the tip of the drill bit in a glass of water every 30 seconds to cool it off. It was a slow process. I was concerned that the bit would wear out and tried a couple of times to switch to a carbide masonry bit to finish the holes, but those just wouldn't penetrate the tile. My concern was unfounded. The smallest bit from this set made it through all 12 holes, slow and steady. Then I enlarged the holes with each next size up until they were big enough. That went much more quickly. It seems that the initial holes are very tough, but enlarging holes is easier. Even my carbide masonry bits worked for that. These bits are a great value, and work wonderfully if you take your time and make sure they don't overheat (by dipping in water). High end diamond bits would have probably saved time, but cost at least 10x as much.

These bits do a great job

I only bought these to mount a tv over my fireplace. Honestly my hopes weren’t too high but they did great, it took me about an hour of drilling, overhead and off balance, I might have applied too much pressure but a little water to cool the bits and it ate right though the brick. They’re a bit chewed up after use but for the price they did an amazing job.

10- piece Masonry Drill Bit set is easy to use... very durable... worked great

Nice set for the price

Great value

Si era lo que esperaba

Not the best set for masonry work used 2 bits to drill 1 hole in brick on the side of my house

Not good quality

Se nota que son de buen material, se siente bastante rígidas, en cuanto al filo me duro lo suficiente para lo que requería, la verdad no se cual sea el tiempo de vida de este tipo de broca o de alguna otra marca, pero en general me parecieron bien en cuanto al precio. Lo volvería a comprar. Nota: para mejorar el desempeño hay que usar un poco e agua en la punta e las brocas.

se desgaste la que use para porcelana to muy duro. pero en otros cerámicos y porcelanatos funcionaron varias veces. Lo mejor es que al ser puntiagudas no se mueven y perforan bien. Mejor que las de widia que compra en la ferretería que son planas y duran lo mismo.

Ca brise vite....

No duran mucho se desgastan muy rápido pero son funcionales de un uso
