Also used it on concrete *by -***- on May 13, 2023* I was amazed at how this cutter worked. It cut through the asphalt like butter; well almost butter, but way easier than I ever thought. I thought it would pull the grinder as it cut, but brand new it did not, and cut through the asphalt easier than I expected.It was the first time I've ever used a tool to cut a v or u groove into asphalt. Previously I've always used a chisel. OMG, this is so much more efficient, faster, and made a clean groove as I followed the crack right across the driveway. It threw up a lot of asphalt dust so wear a mask, and glasses.I went about an inch deep, think I could of gone deeper, but it was a very small thin crack so far, that best I fixed it before it got bigger in the years to come, through seasons.I blower blew out the finished crack of the thick dust that was all over, blew it off, and then melted / filled the groove with hot tar ...OMG, it came out perfect.Anyway, the crack chaser blade cut, helped make it look real professional indeed, and was so easy to use.Expensive, yes... I don't regret it though, and have it to use again if needed for some more times going forward.2024 Edit:I had another opportunity to use this on a concrete garage floor that had a center water drain, but the water in one portion of the floor did not flow to the drain properly because of improper leveling, so I made just a small surface cut from that spot toward the drain using this blade, and that did the trick, the pool of water does not form anymore and drains properly. The blade cut the concrete like butter, wow, and it was so easy to doBy the way, I've attached an image of my Makita GA4030K grinder with this EDiamond Tools 4.5" Crack Chaser Blade mounted on it, my point is to say make sure you mount it in the right direction: Always mount the blade with the arrow on the blade pointing in the direction of the rotation of the grinder. It's important that the 'working back pressure, while using the blade while in contact with work ...is actually pressured Toward Tightening - Not Loosening. ### ⭐⭐⭐⭐⭐ Works great in Granite Boulders! *by D***C on December 6, 2024* Purchased to grind "V" grooves (straight lines) into Granite Boulders. Used in 4.5" angle grinder. This wheel grinds unexpectedly fast and with deep grooves for my project. Ground .5" wide x .5" deep grooves for a total of 6' long . No perceptible wear on wheel ! Lot's of dust, but that's expected. I was thinking of buying an extra grinding wheel as a back up when I'm in remote areas. No need. This grinding wheel will last a long time! ### ⭐⭐⭐⭐⭐ Great product, easy to use and works great, very durable. I'm very happy with this product. *by P***R on September 11, 2020* I am extremely happy with this crack chaser as it works great and it is very easy to use. It quickly and easily cuts through the cement, some have said like a hot knife through butter. Although, I paid almost $50 to get this product I think it's worth every penny as I ground out a number of cracks in my garage and it still isn't even slowing down and it's still very durable. If I ever needed another one I would buy this exact same one again but I don't think I'm ever going to need another one. I highly recommend this crack chaser. ## Frequently Bought Together - 4" Crack Chaser Blade for Cured Concrete, Asphalt Repair or Joint Widen, 0.375" Width, 5/8"-11 Arbor - ALSKAR DIAMOND ADLSS 9 inch Dry or Wet Cutting General Purpose Power Saw Segmented Diamond Blades for Concrete Stone Brick Masonry (9") --- ## 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.hr/products/139033107-4-crack-chaser-blade-for-cured-concrete-asphalt-repair-joint](https://www.desertcart.hr/products/139033107-4-crack-chaser-blade-for-cured-concrete-asphalt-repair-joint) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-25*
