Excellent Core Bit for Tiles – Worth the Money
Very good product, works perfectly. I used it with water to make 2 holes in vitrified tiles — it did the job smoothly, and the bit is still in good condition afterward (picture of status of drill bit after 2 holes uploaded). Definitely value for money. It’s not available in my local market for drill machine, only for L grinders, and those grinder drill bits are quite expensive in offline market. So this online option was a great find with drill machine variant. Highly recommended! Caution: 1. Use with continuous water. 2. Use drill mode only — do not use impact or hammer mode.

Worst Product ever I purchased on Amazon.
I used 8 bits for one hole. Even the hole is not completed. All the bits are cut into pieces in first two rounds..i.e., wherever the powder coating is there.. up to that the hole go and it breaks. Such a cheap product I ever purchased on Amazon. Waste of money. Bits are not quality.

It works only with water, let the water run down the wall and then use this.
Had to do 5 holes. Wasted 2 bits for the 1st hole and took a lot of effort and the hole wasn't even done. Then did a little research, I was using the bits wrong. For ceramic holes it works only with water, make a small pin size hole in 1 liter cold drink or water bottle, aim the water a few inches above the desired hole spot, let the water run down along the wall and then use this bit. With water it worked like it was cutting butter, finished all 5 holes with just one bit.

Nice bit
So far so good. Drilled only two holes with it in porcelain tiles, it was like charm. Earlier I was trying with masonary bits, and really hard time. Wish I had these bits earlier. I don't know how long each bit will last, but hope expect it is value for money. Each hole will take 3-4 minutes. Keep bit cool with water. Only thing I didn't like was bits were slightly rusted when they reached. But no effect on performance

Good quality. Was able to drill 18 holes with 1 bit!
I brought back of 10 because some reviews said it can't drill more than 2 holes. Surprisingly I was able to drill 18 holes with 1 bit! I was able to DIY all the bathroom fittings of my new flat with just 1 bit and it is still good to drill a few more. The trick is to use this bit only until the tile portion is drilled and then change to regular masonry bit to complete the hole.
