QWORK 5 Pcs Set (6, 6, 8, 10, 12mm) Multi-Material Drill Bit Set for Tile,Concrete, Brick, Glass, Plastic and Wood Tungsten Carbide Tip Best for Wall Mirror and Ceramic Tile on Concrete and Brick Wall

I was very unsure about these, but they worked great! Cut through the tiles like butter. Was a little slower with the sheet rock behind the tiles Only problem I had was that since they need water cooling, the water started running alone the bit and into my drill motor. I added an o-ring to the drill which stopped that.

I recently purchased some security cameras for my house and during the installation processed, discovered my standard drill bits could not do the job on the stucco exterior. I needed a 15/64 in bit and couldn't find an affordable option at the local hardware store.As I only needed to drill a few holes, I took a chance and bought these bits. They were cheap so low risk of they didn't work. Well, the 6 mm bit I used worked really well! It took less than 10 seconds to drill 1 hole. I tried to drill with my standard bits and barely made a dent after a few minutes.After drilling 4 holes there seems to be some wear on the bit (see photo). It makes me think these will not last too long, but I'm happy since I don't need to drill through stucco on a regular basis.So, great value option for a DIY'er for minimal work. If I were a contractor I'd probably look elsewhere.

Update: I used the 6mm bit yesterday to install a bath/shower rail set (two rails). The bit worked well for drilling 12 holes in the tiles and the wallboard behind the tile. During installation I dropped the electric drill with the bit in the jaws. The impact with the floor caused the bit to bend. I applied counter-bend force to the bit while in the drill jaws and the bit straightened well enough to continue use. I am satisfied with performance and price.Original review: The set of drill bits advertised as suitable for ceramic tile arrived two days ago. I may not use them for my planned installation of hand rails in the shower/bath for another several weeks, yet I have been asked to evaluate them. I will not rate a product I have not used. I think the request for an evaluation/rating is premature.

Great price and excellent quality

Why did you pick this product vs others?:Meet my requirement. Good price.Size:12mmQuality:Does the job as described

The smaller ones have lasted through some use. The tip on the 1/2" bit wore out almost immediately when drilling into cured concrete. Did work well on tile and brick.

***SAME DAY UPDATE***Used with water as instructed. Got through 4 ceramics tea cups and the drill bit splintered and cracked apart on the 5th cup. I had plans to drill drainage holes into a lot of my pots. Going to return and purchase from a box store specializing in contractor grade tools.***disregard initial review below unless you have a quick one time use for this set. They don’t last. I was able to get through 2 practice coffee mugs and 4 tea cups. That’s it.***Works great for what I purchased the set for.The purpose is to drill drainage holes into ceramic pots for plants.I will update the review after using the set to drill drainage holes into some stone planters, glass, and other pots I currently have.I practiced on chipped coffee/tea mugs that are ceramic. This is what I did with success:1. Use water like the directions suggest2. I put a rag in the sink under the mug to reduce vibration and slippage so I didn’t break the mug or cut myself3. I used the largest 12mm bit.4. I went slow and stopped frequently to see what I was doing and to be careful since I’ve never don’t this beforeThe result was 2 clean holes in the center of both mugs. See the photos attached. I did this in the sink. But, I’d probably do this outside with the hose moving forward with bigger pots.

Needed to drill through shower tiles to install a hand rail. Did you ever try to drill a hole through a shiny, smooth bathroom shower tile? Pretty tough. These drill bits were excellent. Took less then ten minutes to install the rail. If I had to use a nail and hammer to start the holes (and not chip or break the tile) I would have taken a lot longer and not worked anywhere as well. Have used bits for other drilling jobs with great results. Highly recommend. Priced right.
