Suitable for cutting through stone, brick, concrete, tiles, and other masonry materials with ease. For professional builders or home DIY projects, these discs ensure smooth and accurate cutting every time Segmented Diamond Disc Cutting Blade 4.5 Inch diameter Bore 115mm x 1.9mm x 22.2mm Dry Or Wet Cutting for most building materials 13000 Rpm Max 3 in one Pack Tech Traders 3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete Review: Incredible Value – Clean Cuts Through Concrete and Stone Every Time - I recently picked up this Tech Traders 3-pack of Diamond Discs for a landscaping project, and honestly, I am blown away by the performance. You usually expect a "budget" multi-pack to wear down instantly, but these have exceeded all my expectations for both speed and longevity. Key Performance Details: Cutting Speed: I used these on my 4.5" angle grinder to cut through thick garden paving slabs and old red bricks. The diamond segments bite into the material immediately, providing a smooth, fast cut without needing to apply excessive pressure. Durability: I’m still on the first disc after several hours of work. The wear rate is impressively low; the "diamond" edge holds up even when tackling harder concrete blocks. Precision: There is minimal vibration with these discs. They run very true, which means you get a much cleaner edge with less chipping compared to standard abrasive wheels. Universal Fit: They fit my standard 115mm grinder perfectly with no wobble, giving me full confidence while working at high RPMs. Pros: Triple Pack Value: Getting three high-quality discs for this price is unbeatable. It’s great to have spares on hand so you don't have to stop mid-project. Versatility: They handled everything I threw at them—stone, brick, and paving—with the same level of ease. Clean Finish: Very little "burring" or rough edges on the finished cut. Cons: Dust Production: Like all dry-cutting diamond blades, they produce a lot of dust. This isn't a fault of the product, but definitely make sure you’re wearing a good mask and eye protection! The Verdict: These Tech Traders Diamond Discs are a must-have for any DIYer or tradesman looking to save money without sacrificing quality. They are rugged, efficient, and honestly feel like they should cost twice as much. I won’t be overpaying for "big brand" blades at the hardware store anymore. Review: Solid enough to cut through paving stones - Purchased to cut decorative paving stones in half to fit size of job and this worked very well and manages its edge well throughout. The paving slabs I cut in half were not the basic Broadstone style (this would easily cut those) but one tip I learned was score 3/4 of the slab and then snap the slab over something raised and you get a nice clean break without having to cut directly through the thicker slabs. ## Features - Segmented Diamond Disc Cutting Blade - 4.5 Inch diameter Bore 115mm x 1.9mm x 22.2mm - Dry Or Wet Cutting for most building materials - 13000 Rpm Max - 3 in one Pack ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XFNK6HR | | Best Sellers Rank | 2,127 in DIY & Tools ( See Top 100 in DIY & Tools ) 2 in Diamond Blades | | Brand | Tech Traders | | Compatible Devices | Angle Grinder | | Compatible Material | Concrete | | Compatible devices | Angle Grinder | | Construction Type | Super-Abrasive | | Country Of Origin | China | | Customer Reviews | 4.5 out of 5 stars 3,050 Reviews | | Global Trade Identification Number | 00728350991396 | | Grit Material Type | Diamond | | Grit Type | Fine | | Grit material | Diamond | | Grit type | Fine | | Included Components | Tech Traders ® 3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete | | Industry Standard Identifier | 0728350991396 | | Item Diameter | 4.5 Inches | | Item Dimensions | 11.5 x 0.2 x 0.1 centimetres | | Item Dimensions L x W | 11.4L x 11.4W centimetres | | Item Thickness | 0.8 Millimetres | | Item Type Name | Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete | | Item Weight | 320 Grams | | Item thickness | 0.8 Millimetres | | Manufacturer | Tech Traders | | Manufacturer Part Number | Diamond-Disc-Cutting-Blade | | Material | Concrete | | Max Rotational Speed | 13000 RPM | | Model Number | Diamond-Disc-Cutting-Blade | | Number of Items | 3 | | Product Warranty | No guarantee. | | Product dimensions | 11.4L x 11.4W centimetres | | Recommended Uses For Product | Cutting, Grinding, Surface Preparation | | Set Name | 3 in 1 | | Special Features | Dry Or Wet Cutting for most building materials | | UPC | 728350991396 | | Unit Count | 1.0 count | ## Product Details - **Brand:** Tech Traders - **Compatible devices:** Angle Grinder - **Grit material:** Diamond - **Grit type:** Fine - **Product dimensions:** 11.4L x 11.4W centimetres ## Images ![3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete - Image 1](https://m.media-amazon.com/images/I/61UpBkWkSmL.jpg) ![3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete - Image 2](https://m.media-amazon.com/images/I/61GRL6njO2L.jpg) ![3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete - Image 3](https://m.media-amazon.com/images/I/41OjwgnmXIL.jpg) ![3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete - Image 4](https://m.media-amazon.com/images/I/7186v0M0JqL.jpg) ![3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete - Image 5](https://m.media-amazon.com/images/I/71EDKson0KL.jpg) ## Questions & Answers **Q: can these be used to level a flat surface on a very old concrete and pebble wall before bolting down fence pole supports.** A: They are more for cutting than grinding concrete/stone. **Q: Can this cut through composite door reinforced steel frame? Need to fit the door with a gas pipe going through** A: I have cut through steel bolts with these discs so it should. However if the steel has been tempered in some way it may affect the cutting also the length of cut may need more than one blade, I've added this caveat as me usage has been on shortish lengths The issue for me when cuttiing somrematerial was that the body of the cutter stopped it cutting all the way through due to the thickness of the item. **Q: does thi cutting disc fit bosch grinder** A: Just measure your existing disc, this disc comes with 2 adaptors. Good quality disc. **Q: Will these cut through concrete fence post?** A: I used mine to cut breeze blocks which are very hard, they went through them like a hot knife through butter. Concrete fence posts are often reinforced with mild steel rods but these disks should have no problem dealing with them as I've used them to trim 8mm bolts. You will tell if you hit metal as sparks will fly otherwise it's just copious amounts of dust. Wear eye protection and gloves at all times. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Incredible Value – Clean Cuts Through Concrete and Stone Every Time *by M***0 on 24 April 2026* I recently picked up this Tech Traders 3-pack of Diamond Discs for a landscaping project, and honestly, I am blown away by the performance.

Put them in the grinder and away you go. Quality product, sharp solid, and,using them on paving slabs, "slice through" easily. A lot cheaper than in d.i.y. stores! This is my 2nd purchase of these, so that is an indicator of how I rate them. Good buy. ## Frequently Bought Together - Tech Traders ® 3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete - (10PK) 115mm Metal Cutting Discs - Stainless Steel Mild Steel Iron Ultra Thin Profile Slitting Discs Fast and Clean Cutting - 2000W Corded Electric Angle Grinder 115mm Disc Heavy Duty Cutting Grinding --- ## 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.co.uk/products/49100901-3-x-115mm-4-5-diamond-disc-cutting-blade-angle](https://www.desertcart.co.uk/products/49100901-3-x-115mm-4-5-diamond-disc-cutting-blade-angle) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-02*
