LSS 4 1/2 Inch Diamond Saw Blade,Dry or Wet Cutting Saw Blades for Sharp Cutting Concrete Stone Brick Masonry, Broadened Cutter Head (4.5")

This blade has a 1 inch arbor hole which I did notice when I purchased and processed a return under Amazon's generous terms. When looking fir a replacement blade I found DeWalt made a 1 inch to 5/8ths adaptor and that exactly fit my Dewalt 12 inch sliding compound miter saw.With the adapter the blade fits perfectly I canceled the return. Made 1 cut in 2 inch stone 12 inches wide and the cut edge was close to perfect and was as good as the factory edges. Hard to tell longevity from one cut, but the blade looks like new. I have great expectations for this blade and would expect it to outlast the projects I have in mind for it. Suspect this blade should cost about $90 in the big box stores and it woukd be special order, so the Amazon price and delivery time is very good

Great product for the price. Cut bluestone nicely.

Buyer's beware the center ring is not pressed in well. I've had the ring fall out of this 4 inch blade and Whirlwind's 7 inch blade, when I opened the packaging. Easy to fall out, but not so easy to put back in.That being said, the blade cuts well and the price is cheap enough to buy two, just in case.I used the blades to cut a concrete floor for a bathroom drain. The 7 inch blade on my circular saw cut a couple of nice lines a little over 2 inches deep, then I used a jackhammer to break out the concrete, between the cuts. In hindsight, wish I'd used a 10 inch blade, as the concrete floor was 3 1/2 inches thick.Suggest using water while cutting, to hold down the dust and cool the blade. I didn't use water to start with, thinking that my shop vac could handle the dust. I was wrong... a cloud of dust covered everything, clogged the shop vac filter and my dust mask. I also managed to bend the first blade, when it got too hot while using it, without water, on long continuous cuts.

I bought two of these to remove a concrete path around a house. I assumed the lower price would mean lower quality. I have been thoroughly impressed! Even with all the rebar in the material these blades held up really well and stood up to the task.

I fitted this on my grinder to cut wall brick openings. This blade cut the brick like it was butter. I didn't bother to wet-cut with a water supply, but cut it dry. Dusty.... anyway, this blade was the best blade I've ever used for this application. I recommend it.

I used it to make three cuts across an 11' wide asphalt driveway with embedded stone aggregate. The third cut was just as easy as the first. This blade made quick work of cutting these difficult materials, and still looks like new.

I used this blade to cut thru the concrete slab in the house. About a 3' x 3' section. Worked great with no problems. I used my old, reliable 6 1/2 inch circular saw. I did like the directions said and stopped sawing about every minute and let the blade cool off for about 20 seconds. I also poured some water on the slab to keep the blade cool. I think the blade is still good to go for the next project! I attached the larger arbor washer that came with the blade and it worked with no problem. I am happy with the purchase. I think the house concrete slab that I cut thru is about 3" thick. I Still kicked up a lot of dust even using water and a vacuum while cutting.

Doesn’t fit my Makita knockoff. But it is a Makita knockoff.
