I don't often do reviews for products that merely meet my expectations. This one blew them away. I am so pleased at how the diamond cup wheel removed the crusty thinset of tiles so I can reinstall them. I had two dozen of heavly crusted 18 inch tiles, and this product was a beast to chew through the backing (with a lot of dust of course) I used the edge of the disc to create a waffle pattern in the thinset for reliefs on their relaying. I was worried that it may wear out before I was done, but the last tile was cleaned up as fast as the first. Sure beats the disc I used about 6 years ago on a similar project which took a lot more time and heartache. I recommend this product for tile preparation whole heartedly. ## Features - Double Row Segmented Diamond Cup Wheel are designed for grinding concrete and fieldstone, it's an ideal concrete grinding wheel 4 1/2 for angle grinder. - The double row diamond cup grinding wheel is suitable for grinding machines and angle grinders to remove thinset and excess materials on your surface quickly. - The double segment of this diamond grinder cup configuration allows faster material removal ideal for all types of stone like concrete, ceramic, tile, marble, granite, rock, cement, etc. - Using the diamond grinding wheel 4 1/2 inch for surface finishing on concrete, screed, and natural stone like granite, can also be used for the removal of glues and epoxies or thinnest - Durable high-quality brazed Double row segments diamond grinding cup wheel for fast and smooth grinding with 5mm segment height use on both wet or dry surfaces. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N5EI8F3 | | Additional Features | Concrete leveling, Paint Remover | | Best Sellers Rank | #4,028 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Surface Grinding Wheels | | Brand | KSEIBI | | Brand Name | KSEIBI | | Compatible Devices | Air Angle Grinder, Angle Grinder, DEWALT DCG414B, DWE402, Makita 9557PBX1, Bosch 1375A, GWS8-45, PORTER-CABLE PC60TAG,PCE810, Black & Decker BDEG400,G950 Compatible Devices Air Angle Grinder, Angle Grinder, DEWALT DCG414B, DWE402, Makita 9557PBX1, Bosch 1375A, GWS8-45, PORTER-CABLE PC60TAG,PCE810, Black & Decker BDEG400,G950 See more | | Compatible Disc Grinder Tool Models | BOSCH GWS8-45 | | Compatible Material | Stone | | Construction Type | Grinding | | Customer Reviews | 4.6 out of 5 stars 2,489 Reviews | | Grit Material | Diamond | | Grit Material Type | Diamond | | Grit Number | 40 | | Grit Type | Fine | | Included Components | Extra 25/32 Inch Ring | | Industry Standard Identifier | 644030 | | Item Diameter | 4.5 inches | | Item Dimensions | 4.53 x 4.53 x 0.2 inches | | Item Dimensions L x W | 4.5"L x 4.5"W | | Item Thickness | 50 millimeters | | Item Weight | 0.27 g | | Manufacturer | KSEIBI | | Maximum Rotational Speed | 12500 rpm | | Model | 644030 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 644030 | | Product Dimensions | 4.5"L x 4.5"W | | Recommended Uses For Product | Polishing | | Unit Count | 1 Count | | Warranty Description | 30 Day Money Back Guarantee from daet of Purchase | ## Product Details - **Brand:** KSEIBI - **Grit Material:** Diamond - **Grit Type:** Fine - **Product Dimensions:** 4.5"L x 4.5"W ## Images ![KSEIBI 644030 Diamond Concrete Grinding Wheel 4 1/2 inch for Polishing and Cleaning Stone Concrete Surface, Cement, Marble, Rock, Granite, and Thinset Removing, Angle Grinder Wheels Cup - Image 1](https://m.media-amazon.com/images/I/71XlBeU2QWL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: What is the arbor size?** A: The Grinding wheel arbor size is 7/8" and it's comes with extra 5/8" washer . **Q: Can use this cup wheel on wood?** A: This disc is made for grinding all types of stone materials, we don't suggest you to grind wood with this wheel. **Q: Can I grind metal?** A: This disc is made for grinding all types of stone materials, we don't suggest you to grind steel. **Q: Should this be used flat against the concrete surface,or at an angle?** A: Can be used in two positions, depending on the work you need to do. **Q: Do I need any supportive tools?** A: When you grind the stone surface dust will get out, we suggest you to ware your safety goggles and dust mask, you may also attach dust shroud with vacuum on your angle grinder to reduse the dust. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great cutting tool *by R***Y on July 26, 2026* This product will do all you need and fast cutting great price would buy again but finished the job and it didn’t seem to wear the cutting edge at all ### ⭐⭐⭐⭐⭐ longetivity and fast cutting action. *by J***S on August 5, 2026* Man oh man.

There were 2 rings included to change the sizes of arbor and the main one that was on there is what fit for me, but the other one looked like it would fit a slightly larger one. The size of the wheel just barely fit inside the guard, and may have slightly ground away a little, but I'm happy that it worked with the guard in place. I used the wheel to grind down a small ledge in my concrete slab to even out the floor and it worked great. This was way easier than what I had thought to do first which was to pour some leveler stuff down. The grinding was very easy to do and the wheel shows some wear, butt definitely looks like it can do more. Be prepared for lots and LOTS of dust. I was in a closed off room, and that helped, but if you have carpet or anything like that around, you should really try to reduce the dust, and make sure to have a mask of some sort. Overall, very happy with my purchase and the amount of time I saved on this hard job. Hopefully you can benefit like I did. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/40772809-kseibi-644030-diamond-concrete-grinding-wheel-4-1-2-inch](https://www.desertcart.sg/products/40772809-kseibi-644030-diamond-concrete-grinding-wheel-4-1-2-inch) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-01*
