The high quality diamond coating improves the hardness, sharpness and cutting speed of the drill bit and realizes a smooth, high precision cutting edge without damage. 3. The large clearance hole on the side of the drill bit facilitates the pouring of cooling water and the escape of chips during operation, making the drilling process easier. 4. The small hole above the hole cutter helps us pull out the debris stuck in the hole saw with a screwdriver. 5. Suitable for Glass, Tile, Fiberglass, Porcelain Tile, Ceramic, Slate Mable, Granite Light Stone. Not for use on Concrete. Specification: Color: Silver Material: High quality steel & Diamond Sand Hole Diameter: 2-1/2” / 63mm Total Length: 2” / 50mm Package Included: 1 x Diamond Hole Saw Drill Bit Warm Tips: 1. Please keep adding water to keep the drill bit cool and increase lubricity during working. 2. Keep the drilling speed at 800-1000 per minute to reduce the drilling pressure, which can greatly extend the service life of the drill bit. 3. Dry drilling is strictly prohibited for this product. 4. Since the product is measured by hand, please allow a difference of 1-2 mm, thanks! 5. Our image is as consistent as possible with the real object, but due to the equipment, display and light, the color of the two is slightly different. Review: Worked surprisingly well. I used it to cut through stucco/concrete exterior wall. I wanted to install a round 4-1/8 receptacle for a security light and this cut the perfect size hole. Not deep enough to cut through completely, but got me most of the way there. I just used a 1/8 masonry drill bit to drill around and finally, a couple taps with a hammer to break through. Had this been about 1/4 deeper inside, it definitely would’ve cut through completely. Go slow and use a spray bottle to keep it wet. I cut two holes in a wall about 1-1/4 deep, still plenty of life left.

Hard to beat for the price! I have only used each bit a few times, so I can’t comment much on the long-term durability - so far, so good though. --- ## 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.pt/products/561637057-2-1-2-diamond-glass-tile-hole-saw-drill-bit](https://www.desertcart.pt/products/561637057-2-1-2-diamond-glass-tile-hole-saw-drill-bit) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-06*
