Size: 10pc Diamond bits 3/16" to 5/8"
Needed to drill some holes in porcelain tile to hand some towel racks and the drill bits worked great. Sprayed a little water on the bit while I drilled and the holes went smoothly. Drilled four holes with no problems.

I've only used these to drill about 6 holes through tile and durock so far, but they're holding up well (same but used for all holes). Wobbling the bit to creat the hole does up size it a bit, but decent quality bits. The wax used for lubricating makes pushing the tile nub out a bit tricky, but I chucked a smaller but in a drill and cut through the wax from the base of the bit and the nub popped right out. Again, I think these are decent quality and will serve to cut many a hole. Don't use too much pressure, let the bit do the work.

Size: 5 Pcs 1/2“ Diamond Bits
Works well with patience and water to cool. A bit undersized but generally pretty good.

Size: 5 Pcs 3/8“ Diamond Bits
Drilled through old powerline insulator in about five minutes. Pictures are of the first one I drilled through so it’s a little bit sloppy. Entry and exit wounds will probably chip. Tips and tricks: I’d say stay at the 45° angle longer than you think you need to and then slowly move to be perpendicular to your service. Very slowly. This might take a full minute or more. If you try to go perpendicular too fast, you will slip and make the scars that you can see in my pictures.

Size: 7 Pcs Diamond Drill Bit
I used this to drill holes in the bottom of porcelain or maybe they were stoneware mugs in order to use them for flower pots. At first it was an arduous task. I checked out some YouTube videos first on “how to” and learned the correct method positioning the tool at 45 degree angle at first to get the hole started then gradually turn the drill perpendicular to the mug to get a nice round hole. You have to let the drill do the work without a lot of pressure. And I used water on the bottom of the mug for lubricant. The first one took 30 minutes but with practice I got it down to about 8 minutes a hole. I had 11 to do. The bits themselves worked great! They didn’t get dull at all and did the job efficiently.

Size: 5 Pcs Diamond Bits
The media could not be loaded. See my video of what I was drilling. Ok,I used water for cooling I (painfully) removed the inner slug which took me several minutes to removed the just 1/8" thick slug of stone. That was the worst part of using these. Then by the time I was 3/4" down the but seemed to stop working even though I was pulling & soaking it with water it jyst seemed to stop working. The 1st 1/4 inch of drilling was a unbelievably fast but then, the inevitable became apparent. It took about 15 to 20 minutes to dtill a 1/2" hole thru hard stone. I know it was a hard stone with quartz in it so I understand that being a moh 6 and diamonds are moh 7. I was pushing the limits of these drills so thats why I was taking it easy and using alot of water but they should still last longer then ONE HOLE for god sakes.my other diamond 💠 drill bits last hours drilling thru solid quartz crystals. And they are very cheap but work well. These are very disappointing 😞 O yeah by the way I had to use TWO bits to get thru this ONE STONE. I used a 3/8" dia drill 1st which took my at least 1/2 hour (drilling then clamping the bit in a vise so I could hammer a smaller drill bit thru this and knocking the slug out and repeating several times!) What a pain in the ass. Luckily redrilling the same hole with a 1/2" ALL FOR JUST ONE HOLE. Drill went a whole lot faster. But what a pain.

Hard to start and keep the bit centered. Material gets stuck in the bit and is near impossible to remove. They are pretty cheap and start breaking pretty quickly. They did the job once, but probably won't last another.
