4" Crack Chaser Blade for Cured Concrete, Asphalt Repair or Joint Widen, 0.25" Width, 5/8"-11 Arbor

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.

I bought this to open up cracks in my asphalt driveway so I could lay pli-stix into them with ease. This baby made easy work of the asphalt. The only problem i had was the old latex crack filler that was in there already would gum up the grinding wheel. This is not the crack chasers fault. Just know that if you have that stuff in there it will be a problem. I was able to work through it in the end. The spots where I hit just pavement this thing worked like a dream. It also held up after hours of use. Still looks new!

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.

this tool worked well and saved me alot of time

I bought this to "chase" i.e. "widen" some small cracks in my concrete driveway so I could fill them with crack repair caulk. It worked perfectly and was very, very fast as well. I chased around 50' of cracks and it looks like it is pretty new so should last a long time. Expensive, but for the right tool it was worth it. (I had bids of $10/foot to do this simple repair).

I had cracks with that gray caulk already in them. I dug out as much of the patch caulk as I could and then used this to clean out the cracks. You need to get the majority of the patch caulk out, but then this will clean that crack up with no problem. I had extensive cracks criss crossing a garage floor and this cleaned them up in no time.

Blade worked great on my angle grinder. Hooked right up. Word of advice, wear your safety glasses, clothing and a hat you don't care about getting dirty and dusty.Otherwise it tracks the cracks in your asphalt really well and easily opens them enough to get a good amount of crack filler in them.After doing all the cracks in my driveway, the blade was dirty but still looks like new.Grinding in cracks that were filled previously is messy (sticky stands (almost like cotton candy consistency) of tar) but it pulls off easily enough.Didn't try it on concrete but guessing it would work equally as well for that.

Tool works really good, took very little time To cut seam and make ready for repairs.

Excellent
