Package includes: 15 x glass drill bit for bottles Review: First of all, you're not getting professional quality Diamond hole saws for $8. That said, these work amazingly well! I cut out a small section of tile for my claw foot tub in about 30 seconds. Here's what you need to do to get nice round holes: 1. Have a small vessel of water to dip the saw into before you start and at intervals as you are drilling. Lay out (mark) your exact hole location with a full circle so you know exactly where to start. Start by tilting your drill at about a 5 degree angle and spin it FAST. Diamonds cut best at higher RPMs. Slow will work poorly and slowly... fast works much better because you aren't having to try to steady the drill as much. As you start cutting on your circle mark, slowly decrease the angle (square to the surface) so your drill begins making contact with the full circle as it cuts through. Once you've made full contact all the way around the circle, you can apply more pressure. Don't forget to cool the drill about every 15 seconds of drilling time by dipping it fully into the water. The water will fill the groove as you cut. It also acts as a lubricant to clear the dust and speeds cutting. Wetter is better! If you can dribble a steady flow as you drill, even better. I cut a 2in and also a 1in hole perfectly round with this set of hole saws. They work great. They arent prefect but they definitely do the job nicely. For the price, you can't beat these! I only needed a couple uses but these will cut many holes if used properly.

I would strongly advise if you do try it, use water to help with the friction. It says that you can use it on stone , gemstones, rocks, and pebbles. Hopefully that answers your question **Q: what is the chuck size 3/8 or 1/2 , I have 3/8 inch chuck?** A: I have a dewalt drill with 3/8 in chuck its perfect. **Q: What maximum thickness are these suitable for? What is the thickness of the diamond dust on the smallest three cutters?** A: I can't tell you in exact dimensions how thick the coating of the cutters are. I can tell you that I cut a hole through a substantial hi-power electrical insulator big enough to run a 120-v plug through. Before using these bits-nothing could touch the ceramics it was made of. The secret to success is to run water on the project while drilling. **Q: What machine can i buy for the drill bits?** A: and drill will work, cordless or corded ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***A on 23 December 2025* First of all, you're not getting professional quality Diamond hole saws for $8.

The variety of sizes in the pack is excellent, covering almost any small to medium hole you might need for bathroom fixtures or kitchen backsplashes. They cut through ceramic and glass cleanly as long as you use enough water to keep them cool. In terms of durability, they don't last very long. You might only get a couple of good holes out of each bit before the diamond coating starts to wear off. However, considering the very low price for a 15-piece set, I knew exactly what I was getting. It’s much cheaper to buy this entire pack and use them as 'disposables' than to buy one single professional bit that costs five times as much. If you are a professional contractor doing this every day, you might want something higher-end. But for a DIYer or someone with a one-time project, these are perfect. They are effective, affordable, and get the task done without breaking the bank. Just remember to use low speed and plenty of water, and they will serve you well for the price! ## Frequently Bought Together - 15 Pcs Diamond Drill Bits for Ceramic, Diamond Hole Saw Drill Bit Set Kit, Premium Glass Drill Bit for Bottles,Pots, Marble, Granite Stone, Tile Cutting 0.23 Inch - 2 Inch（6mm - 50mm） YLYL - 6 PCs Diamond Drill Bits Set for Porcelain, Ceramic, Glass & More - Versatile Tile Drill Bits for Efficient, Precise Drilling - Professional Masonry Drill Bit Set (10PCS) for Glass/Brick/Plastic/Cement/Wood/Tile/Etc, Industrial Strength Carbide Drill Bit Tip, 1/8"-1/2" by TITGGI --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/318561496-ylyl-diamond-drill-bits-for-ceramic-diamond-hole-saw-drill](https://www.desertcart.jp/products/318561496-ylyl-diamond-drill-bits-for-ceramic-diamond-hole-saw-drill) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-19*
