BGTEC Dry Diamond Drill Bits Set - 1/4" 6mm 5pcs Tile Cutter Hole Saw and 1/4" 6mm 5pcs Carbide Tip Drill Bits for Granite Marble Porcelain Ceramic Glass

Best when used with water

For ceramic and porcelain use as much water to cool as you can I’ve ordered these 3x not because they were out but because I can’t live without them!!

We got the new fiber cement siding which bends a lot of nails. I couldn't even get my regular drill bit to make a pilot hole. These tips do that trick. I don't go at top speed but I've been able to drill pilot holes and mount the things that need mounting.

I needed a set of drill bits that could handle a variety of materials, and this set seemed to fit the bill. I’ve used these bits on wood, ceramic tile, and even some concrete, and they’ve performed really well. The angled head is great for getting into tight spaces, and the carbide tips seem to be holding up nicely; I haven’t had any issues with them dulling quickly. The different sizes are also super useful—I've been able to tackle a bunch of different projects with this one set. I’m not a professional, but I do a lot of DIY stuff around my place, and these bits have made the job a lot easier 🕳️. I’d definitely recommend this set to anyone looking for a great and durable drill bit option.

We needed a special drill bit set to drill some mounting holes in tiles. This set was perfect for the job. Drill bits worked very well. Great product.

These diamond core drill bits are well made and heavy duty. There is a good variety in this set and I strongly recommend.
