Diamond Drill Bits Set, 10 PCS Diamond Hole Saw Set, Glass Drill Bit for Ceramic Tile Porcelain Marble Granite Stone Bottles

This Diamond Drill set worked well for my DIY replace shower tiles bathroom project. I was skeptical at first because it only cost $10. However, I didn't want to buy an expensive set for a probable one time use. I needed openings for the shower head, faucet, and water spout. This set was definitely worth the money. Pictures included to show the hardware holes made with these drill attachments. We were not overly aggressive. One picture shows when we cut the holes before install, one picture shows the bottom tile hole on the wall, and one picture shows the top hole on the wall.

Works amazing. I bought these to drill holes in the bottom of flower pots. I put a piece of tape on the bottom and started the bit at an angle and as soon as it made a mark in the ceramic I was able to go straight in. Drilled through 1/2 thick flower pots in 30 seconds with no breakage

For how cheap these are they worked quite well. Cut through glass quicker than a name brand for me

Work very well....good price

I bought these drill bits to add drainage holes to a small collection of ceramic and clay pots that I've accumulated over the years. Some are small - think 2" individual cacti and succulent pots-- a few in the 8-10'" range, and one 16" monster with walls an inch thick.I'm happy to report that all now have cleanly cut drainage holes, and that it took no more than a minute each for all but the big one, which nonetheless took only a few minutes with the one inch bit.It's crucial to follow the two pictographic instructions: 1) Start the hole with the bit at a 45 degree angle to the work surface and once it "bites" return to 90 degrees, and 2) keep the bit wet. When first starting, keep the drill speed low, and use both hands to hold it in place, as the bit will want to walk.I gave these 3 stars in the durability category only because while the 1" bit did its job, it is now completely worn out and in the trash. That said, these are inexpensive, they work just fine for my needs, and I wouldn't hesitate to buy them again.

Semderm Diamond Hole Saw Kit worked well. First time drilling glass and it was easy with this kit. There appears to be plenty of diamond material for many holes, so good quality for the money.

These drill/annular cutters do work very well. I have used them to drill holes in four different ceramic pots. The ones that I have used cut very well. My only issue with these is the damaged one that was in the package of cutters. It was obviously damaged before the chrome coating was applied. So it is a good product for the money. It works well so far. They just have a QC issue in their manufacturing.

Actuality as described and the quality is good.They are heavy weighted so will cut any of the products listed as being able to cut.
