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

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.

***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 suggest 2. I put a rag in the sink under the mug to reduce vibration and slippage so I didn’t break the mug or cut myself 3. 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 before The 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.

Broke very quickly

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

I bought the 8-piece metric set (ASIN B08QZK4M66) with my hard earned money based on the overwhelmingly positive reviews (64% of the reviews gave QWORK drill bits a 5 star rating and 17% of the review gave it a 4 star rating). I've never heard of QWORK before, but I took a leap of faith and gambled away the few dollars I have for a much needed tool. Very unfortunately for me, the bit I used (the 6 mm size) broke its tip half way through drilling the first hole in a marble tile. I ended up purchasing a Milwaukee 4-bit set for 3 times the dollar amount of this QWORK set. Having learned my lesson, I also purchased a Milwaukee diamond tipped bit (in the size I need) as an added insurance. I've always had pretty good luck using Milwaukee masonry bits in the past for drilling concrete, bricks, and stucco, and I probably should have stayed with a brand that has served me well. I purchased the QWORK product based on my current financial situation, and I had hoped this product can actually save me money. Alas, my hope turned out to be a pure fantasy, and I ended up spending more of my precious money on the project than I had intended. What a huge disappointment. So, no, I do not recommend this QWORK product.
