Diamond Drill Bit Set

"These are actually a Godsend! I recently have purchased a ton of succulents to care for, and the pots I had didn’t have any kind of drainage. After doing some research I realized I needed to put some drainage holes in those suckers fast. I used these on- a very large, thick concrete pot, 2 mason jars, an acrylic pot, and a terra-cotta one. These bits went right through all of the things listed above with ease. It worked wonderfully! No cracks, was super fast, and perfectly round pretty holes. I’m so so happy." - Kimberly P., MO

I am a fish fanatic and i deal with fish tanks a lot. That was the reason why i bought this set. I need to drill holes to have a sump filter connected to my tank. This product was a perfect solution for that! I can drill as many holes as i want! Perfect!

Love it! I purchased these to drill holes in our glass and ceramic planters. They work like a charm! I have used 3 sizes of bits to drill holes in at least 15 pots and i have had zero casualties. I did start with our least favorite and cheaper pots first, just to make sure they worked. Then I felt confident enough in these bits that I even used them on some of vintage, one of a kind pots too. Highly recommended!

This is a must have! I bought these to be able to cut holes in tile and other masonry surfaces. I do a lot of DIY house repair and you need to be able to drill into anything. Works just as expected! Great set!

I bought these because I was remodelling my bathroom. I had to make holes in both tile and mirrors for new fixtures and plumbing. I am pleasantly surprised. The result were fantastic, tile cut well and clean enough. I used a light oil, to keep friction and heat down, they worked like a charm.

These are great for making wine bottle lamps. We drink a lot of wine, its been great to have a use for the empty bottles outside of a landfill. They drill through glass perfectly! I'm very happy with my purchase!

I normally don’t do reviews, but I had to do a review of these amazing drill bits. Recently I made a beautiful glass bottle wall. For each of the 100+bottles I had to drill a hole in the bottom. These drill bits were my saving grace!

I am not all that handy with tools, but needed to drill small holes in glass vases for a project. I was very apprehensive, but these worked perfectly, and I was able to successfully drill 6 vases. If you are drilling glass, make sure to keep the bit wet. An amazing drill bit set!

So great! These bits were able to easily drill through my tile in the shower. I used this bit set to drill 6 holes for the shower doors I was installing and compared to my other shower door installation, this was much easier and less hassle. Just what I needed!

I used these bits to drill holes in plates to make cake stands. They worked very well. Drilled 6 plates with no cracks or problems! Perfect!

I like this drill bit set so much because it has different sizes and I can use to drill holes on planters that don’t come with it. I also use it to drill holes on cups that I later convert to planters. Was very easy to use it! Love it!
