Features:

  • GENERAL USAGE: Diamond Hole Saw bits are versatile drill bits that allow you to cleanly cut glass, ceramics, porcelain, ceramic tile, porcelain tile, limestone, slate, marble, granite, light stone and fiberglass. Most importantly with diamond drill bits you greatly improve the accuracy of the hole than standard bits. *It is important to note that you must keep your drill bit wet as the friction of the bits and materials build up heat quickly.*
  • QUALITY: Made from high strength carbon steel makes these drill bits durable and precise. Steel construction also makes for a longer lasting tools set. When you need to drill holes rest assured these bits will be ready. Nickel-plated with a diamond dust coating offers superior performance and cutting strength
  • PRECISION: All the bits are processed for a smooth and exact finish. This type of production leads to a consistent product where every job is done fast, efficient and correct. Will work with all electric drills. Cuts clean, perfectly round holes to a depth of approximately 7/8 inches

Worked great.

They cut through the holes in my clay pots without cracking them. They are a little tricky to start a hole because they don't have a point in the middle. You could probably drill a hole in a board and place over what you are drilling then have more control. But at the time I was in a hurry. They are a bit smaller than I realized but I am not someone whole drills much and knows much about these things. These fit on my regular drill. A controlled tork drill may be easier to use to get the hole started. But they worked perfectly, you really can't beat the price.

Great for drilling holes in clay pots

I like to go thrift store shopping for old ceramics and clay bowls. These are just what I needed to drill holes in the bottoms of them so I can put my plants in them. I have drilled about 5 bowls with these and have had no issues at all with them.

Diamond cutting bit cuts like butter

I was surprised how well it cut through porcelain tile. I built a putty dam to hold the water over the cutting spot and applied very little pressure to the bit, and it cut right through. Very happy. I looked at the tip and could see some diamonds missing after one hole, that is why I gave longevity a three star. It did what I purchased it for and am happy.

Easier to Cut Glass than I Imagined

I love these drill bits. It is so easy to make holes in glass (do create a template out of wood with a regular bit first to hold these bits in place when you first start to drill). I bought them to cut a hole in a wine bottle, and have since used them on a couple of ceramic planters and other glass bottle.

Inexpensive and very durable

I have used expensive tile cutting bits before and was only able to get a few cuts made before the blade dulled. These bits came in a pack of 3 sizes and were very inexpensive so I did not expect much. As soon as I got them, I used the mid size bit to cut perfectly round holes in glass plates for a craft project and after cutting 15 holes in a couple of hours (under running water to keep it cool) the bit is still functioning like new, and I did not break any plates! I am very happy with these bits and will buy more if these ever go dull!

I only use diamond for cutting glass!

Don't use carbide bits to cut glass, only to break your expensive item. Use diamond tools. These cut well and smoothly without breaking the glass. You can cut holes and smooth / form edges.

Works great!

I bought these to make a holes in ceramic and glass planters. I'm not very handy, but this was super easy and there were no injuries to my hands or fingers (I was really nervous). Holes are smooth and no cracks found afterwards. The piece comes out as a perfect little circle that you can just pick up and throw away. Edit: The white stuff next to the hole is a price sticker, not damage to the pot. I left it partially on to help stabilize while drilling under water. Hole is completely smooth. This hole was made with the middle size bit.

Works great

I was nervous to use these, but I had a mirrored bi-fold closet door with no handle on it. I used the smallest bit to make 2 holes in the mirrored door to add a door pull. I'm an amateur DIYer but I've never drilled holes in glass before. I watched some youtube videos and followed suggestions to start by grinding the hole area at an angle before bringing the drill perpendicular to the glass. It took some time, as I didn't want to press too hard and break the door, but it was a successful venture!

Perfect for making drain holes pots!

I love finding cute little containers to use a succulent pots. However I always run into the problem of proper drainage. I finally caved in and bought these drill bits (honestly thought they were going to be more pricy so I never thought to bother). These worked perfectly!! I listened to what others said and made sure to properly lubricate it while drilling by setting up my hose to constantly drizzle some water on the pots. I now have 4 new succulent containers and a big smile on my face! Definitely recommend for simple projects like these

I love gardening but am on a limited income

I am a new DIYer as a 72 year old female. I love gardening but am on a limited income. I wanted a drill bit that I could drill holes in inexpensive ceramic pots for planting and for drilling a hole in little knick knacks to use to make cute little water fountains for my container gardens. I have already made a cute mushroom fountain and tonight I just finished a cute turtle fountain in a birdbath. Even for someone that does not know what they are doing, I am able to use the drill bits. I need a little practice since I made a tiny chip near the hole I drilled, but I will learn with practice. I am using just "dollar store' pieces for the water gardens so they aren't expensive pieces at all. I'll practice on the cheapies before I try something I pay a little more for. I do love the drill bits - they make me feel so 'handy', LOL.
