10-Piece 3/16" Masonry Drill Bits for Tile Glass Ceramic Wall Brick Stone Soft-Metal Wood, 1/4 Inch Concrete Drill Bits Cement Drill Bit Set, 3-Flat Shank, YG8 Carbide Tungsten Steel Alloy Tip 5mm

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.

Finally had an opportunity to use these. Drilling into concrete block, 12 holes later and the bit was still doing a great job. A significant upgrade over the cheapo bit that cam with the mounting screws inserts. I am truly impressed. Great quality!

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.

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.

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

Let’s start by saying, don’t waste your money/time on these drill bits. Bought these because first off, they were “cheap”. Well, you get what you pay for. Hardware store was closed at night and needed a 5/32” masonry bit for drilling a few holes in concrete block for 3/16” tap cons. Bought these to have overnight delivered early AM to finish the job. Drill bits said they had other plans. Went through 3 bits in 2 holes, ran to hardware store when they opened at 8 AM and bought a Bosch bit and finished the job without issue. Moral of the story, you get what you pay for.

Bought these to drill wholes in my ceramic planting pots for proper drainage. Worked like a charm. They seem good quality and I know they'll come in handy for other things.

So I buy a lot of pods to use for gardening and they need drain holes in them and this is like going through butter. This is a game changer. I also take mugs. I find at yard sales and thrift shops and drills holes in the side and hang them for my trees it’s just a whimsical thing game changer.

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
