Review: 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. ## Features - 【Diamond Drill Bits】These drill bit kits are made of upgraded carbon steel with smooth nickel plating surface to resist corrosion, sharp and durable without edge collapse. - 【Premium Quality】Coated with high quality diamond to improve drill efficiency and creates a sharp, high precision and smooth cut. - 【Hole Saw Set 10 Sizes】1/4", 5/16", 3/8", 1/2", 9/16", 5/8", 11/16", 4/5", 7/8", 1-1/5"，to meet various drill needs. - 【Versatile Uses】Diamond hole saw drill bit set kit are used to drill Glass, Porcelain, Ceramic, Marble, Granite Stone, Bottles, KEBESNELFA, Pots. - 【Tips】Please keep adding water when drilling to extend the life.Besides the water lubrication will improve the drilling experience. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B24RXXDJ | | Brand | Semderm | | Customer Reviews | 4.4 4.4 out of 5 stars (1,897) | | Cutting Angle String | 6E+1 Degrees | | Cutting Diameter | 40.64 Millimetres | | Finish Types | Carbon Steel,Nickel | | Item Weight | 1 Grams | | Manufacturer | Semderm | | Material | Marble,Glass,Nickel,Porcelain,Carbon Steel,Stone,Diamond | | Minimum Bore Diameter | 6.35 Millimetres | | Model Number | Semderm0001 | | Number of Flutes | 2 | | Point Style | Diamond Point | | Shank Type | Straight | | Surface Recommendation | Glass, Porcelain, Rock, Tile | | Tool Flute Type | Straight | | UPC | 605500325624 | | Unit Count | 10.0 count | ## Product Details - **Cutting angle string:** 6E+1 Degrees - **Cutting diameter:** 40.64 Millimetres - **Finish type:** Carbon Steel,Nickel - **Material:** Marble,Glass,Nickel,Porcelain,Carbon Steel,Stone,Diamond - **Shank type:** Straight ## Images ![Diamond Drill Bits Set, 10 PCS Diamond Hole Saw Set, Glass Drill Bit for Ceramic Tile Porcelain Marble Granite Stone Bottles - Image 1](https://m.media-amazon.com/images/I/71fK7FgktvL.jpg) ![Diamond Drill Bits Set, 10 PCS Diamond Hole Saw Set, Glass Drill Bit for Ceramic Tile Porcelain Marble Granite Stone Bottles - Image 2](https://m.media-amazon.com/images/I/61TGOMvAGmL.jpg) ![Diamond Drill Bits Set, 10 PCS Diamond Hole Saw Set, Glass Drill Bit for Ceramic Tile Porcelain Marble Granite Stone Bottles - Image 3](https://m.media-amazon.com/images/I/61Qc6csx69L.jpg) ![Diamond Drill Bits Set, 10 PCS Diamond Hole Saw Set, Glass Drill Bit for Ceramic Tile Porcelain Marble Granite Stone Bottles - Image 4](https://m.media-amazon.com/images/I/61v9kWyLXuL.jpg) ![Diamond Drill Bits Set, 10 PCS Diamond Hole Saw Set, Glass Drill Bit for Ceramic Tile Porcelain Marble Granite Stone Bottles - Image 5](https://m.media-amazon.com/images/I/71iumBHtg7L.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: What size is the shank? Will they fit a 1/4inch drill?** A: The shaft of the diamond bit is just a bit bigger than a 1/4 like 5/16 if that’s what you are asking. Must use a drill that is adjustable to accept the round shaft. **Q: Will it work on an alluminum 1/8" sheet?** A: Hello, Diamond hole saw will not work on alluminum. Maybe carbide burr set will work on alluminum. **Q: Can these work on wood? I have an old rusted screw that snapped off inside a chair leg.** A: Not likely. These bits are like a hole saw - an empty shell that cuts on the outside diameter only. Get a screw extractor bit for that size screw, chuck it in power drill, set drill to reverse and let it go into the screw and remove it automatically. **Q: Can I use to drill hole ~ an inch or two wide on mirrored glass?** A: No, it not going to work. Must be a drill designed for glass. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by E***. on 14 February 2026* Fast postage and great deal.
