7PCS Tungsten Drill Bits Set Tungsten Carbide Tip Drill Bits Masonry Drill Bits Set for Porcelain Ceramic Tile, Concrete, Brick Wall, Glass, Mirrors, Plastic Masonry and Wood (3 4 5 6 8 10 12mm)

These bits are absolutely fantastic. I was using standard Bosch masonry drill bits and I always had to apply much pressure on the drill to get the drill bits further through. This took a lot of energy and effort. I'm comes these bits...I was hesitant because of the much lower price and shape of the tips of these bits. However, I couldn't believe the ease. These went through brick so effortlessly and I did not even need to apply anywhere next to the pressure I used to. It took me 15 seconds to drill through brick with these bits compared to about a minute with the much more expensive brands.No idea how long the bits will last as I only used them on two jobs. But, I would still very highly recommend these.

For drilling into masonry the first time ever, it was surpriusing how easy it was and it's probably due to getting these drill bits.Case is very cheap and nasty but the bit themselves are where all the money should go to and they deliver great. Although one drill bit is now already quite worn down the bigger ones which Ive used more are still in great condition so it may be due to my own amateur abilties. (Drill fast for concrete, that worked for me)Would definitely recommend this bit set, very good price and great results.

I have seen these on "other" selling sites and I decided to give them a go. I won't lie, I haven't tried them on the vast majority of the materials it says its made for, concrete however, yep they work and you can tell just by holding them, they are robust! They obviously drill through wood with little issue. The range of sizes are good however I hope you guys think before you act, because all it takes is reading a little reading in order to ensure you have the correct sizes.

I needed a 12mm drill bit and came across these. I wasn't expecting too much because of the price but I only needed to drill 4 holes. Received them through Amazon Prime, as always a super quick delivery. They come in a cheap, flimsy plastic case which don't do much to convince you of the quality. However, when it came to using the drill bits I was blown away. They absolutely fly through brick. The pointed tip makes so much difference. I've never had such an easy time drilling holes before. It was like drilling through plaster board. Now I don't know how long these will last but for the price they are excellent. Highly recommended.

Useless. Second hole through tile on a very low speed and the tip broke clean off.[update] Contacted the seller and got a full refund so at least they provided very good customer support.

Needed to go through very thick porcelain wall tiles. I had a regular stainless steel tile bit that managed to do 2 of the 4 holes I need to drill before it eventually shattered inside the hole (despite constantly cooling it down), on top of that it took a lot of force and drilling to get through the tile. Anyway bought these as a replacement and i did the final 2 holes in about 3 minutes. It just slid right through the tile with minimal effort. Excellent quality.

Really easy to drill wall tiles with these bit and there are 7 different sized bits to choose from so gives good options if you need to drill a small or big hole. Seem good quality for the price as well.

Decent quality for (Chinese) quality for the price....TCT tips burnt out pretty quickly but I WAS drilling into Italian porcelain tiles and they are HARD M/ F*&$’ckersIf you are only requiring Spear Pints for low grade glass or Ceramic, you should be fine- BUT be aware that these will only be effective against quality European/ American (aka. First world) Ceramic for max. 15-13 mins. before burnout....RECOMMENDED for one-off drilling only in/against relatively “normal” substrates........
