Please buy this

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.

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.

Excellent product which was more effective than I had hoped

These bits worked well going through very hard travertine tile to mount some shower safety bars. With a regular drill instead of a hammer drill you need to go slow in 4 to 8 second bursts and dip the bit in water each time. Takes a little while but does a clean job without cracking.

Very frustrating, especially when trying to finish a project and you trust the tools you bought will be reliable. I tried to drill a hole in a brick (which was alaimed as a very easy job with this drill bit. The 5/6 bit couldn't even penetrate 1/4 inch and the tip is gone and flat. Tried two drillers in case that was the problem but it was not. The problem is the low quality of the drill bit. I will return and definitely not buy this brand again.

A pleasant surprise. These drills effortlessly cut through ceramic tile, leaving a perfect hole. No chipping or flaking.

The product is good but not great they kept on breaking

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
