Review: Great for a machine shop - This is exactly what I needed for cleaning up the surface of my milling machines. The stone has dual grit, which isn't really that useful, but I suppose the rough side could be used for larger burrs and oopsies on the mill. The fine side is perfect for finding and smoothing down the mill table. It's also useful for cleaning up the bottom of Kurt vices and any other part of a machine tool that should be flat. Review: It is a real Norton's stone. - I saw a few reviews saying questioning its authenticity of being a Nortons product. I can confirm it is a real Norton's stone. I was a little nervous since seeing the reviews myself but still took and chance. Using this for my mill and CNC ## Features - Combination oilstone has 100 grit on one face for repairing cutting edges and 280 grit on the opposite face for sharpening and maintaining them - Silicon carbide sharpens to moderate tolerances when it is more important to sharpen the blade quickly than to produce a fine cutting edge - Disk-shaped for hand sharpening of machine knives and garden or household cutting tools - Groove around circumference of stone for secure hold and protection of fingers - Compact for easy portability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000RU8TQA | | Best Sellers Rank | #147,842 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #245 in Sharpening Stones | | Brand | Norton | | Brand Name | Norton | | Color | Gray | | Customer Reviews | 4.4 out of 5 stars 95 Reviews | | Grit Type | Fine | | Included Components | 1 Sharpening Stone | | Item Dimensions L x W x H | 4"L x 4"W x 1.5"H | | Item Type Name | Abrasive Machine Knife Stone | | Item Weight | 16 ounces | | Manufacturer | St. Gobain Abrasives | | Manufacturer Part Number | 07660701580 | | Material | Carborundum | | Material Type | Carborundum | | Model Number | 61463687570 | | Number of Items | 1 | | Number of Packs | 1 | | Product Dimensions | 4"L x 4"W x 1.5"H | | UPC | 614636875705 | | Unit Count | 1 Count | ## Product Details - **Brand:** Norton - **Color:** Gray - **Grit Type:** Fine - **Item Weight:** 16 ounces - **Manufacturer:** St. Gobain Abrasives - **Material:** Carborundum - **Number of Items:** 1 - **Number of Packs:** 1 - **Product Dimensions:** 4"L x 4"W x 1.5"H - **Unit Count:** 1 Count ## Images ![Norton Crystolon Abrasive Machine Knife Stone, Silicon Carbide, 4" Diameter x 1-1/2" Thickness, Grit Coarse/Fine (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/61eIEWRHdQL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for a machine shop *by B***N on March 24, 2014* This is exactly what I needed for cleaning up the surface of my milling machines.

Using this for my mill and CNC ### ⭐⭐⭐⭐⭐ Fits well in the hand. *by A***W on February 25, 2019* I use these to stone the burr on my CNC. I like the groove, it’s easy to hold. The size is perfect to manipulate. I use the fine side the most but it’s nice having a course side Incase a burr is particularly nasty. Norton is the Bomb. ## Frequently Bought Together - Norton Crystolon Abrasive Machine Knife Stone, Silicon Carbide, 4" Diameter x 1-1/2" Thickness, Grit Coarse/Fine (Pack of 1) - Norton 61463685545 (IB64) India AO Combination Grit Sharpening Benchstone, Aluminum Oxide Abrasive, Coarse/Fine Grits, Orange/Brown Colors, 4" x 1" x 1" - Combination Grit Sharpening Stone, 4" x 1-1/2" x 1-1/2", Coarse/Fine, Silicon Carbide --- ## 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.sc/products/7792506-norton-crystolon-abrasive-machine-knife-stone-silicon-carbide-4-diameter](https://www.desertcart.sc/products/7792506-norton-crystolon-abrasive-machine-knife-stone-silicon-carbide-4-diameter) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-01*
