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 purchased this item to set some anchors in bricks, they were adequate for the job I needed them for!Price point, I thought, was pretty good!

Very good bits

perfect for drilling holes in Plant Pots

This item worked perfectly for drilling into cement block. It maintained its diameter despite heavy use.

***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.

Bit broke after 1st hole. Use water while drilling.

They worked well for my application and the price was good.

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.
