Question: will it fit the dc411
Document: works really well.I have cut my granite piece (1&#34; thick) without any hassle.It cut that stone like a butter. highly recommend.
good quality blade. heat disapation good and no "warping" with continuous use. I got a Bosch grinder.
Worked great for cutting out a circle on some hard porcelain tile and still has a lot of life left in it.
Why in the hell would a company like DEWALT sell this item without DEWALT DW4706 4-1/2-Inch Backing Flange for the DW402, DW402G, and DW818? I bought the 4 1/2 inch grinder and this blade will not function without the backing flange. The flange is not included with the grinder and no mention of the flange is included in the requirements for this blade or the grinder.
Using this blade will instantly bring to your mind a hot knife through butter! Honestly, you will literally envision it the moment you start using this blade. Well worth it.
Used it to cut two inch concrete paver blocks and worked great. Had to cut both sides then used a masonry chisel to break in two. Cut about 30 concrete blocks and still has cutting edge left.
Used it to cut concrete block, worked great and worth the few extra dollars over composite blades, fill an old spray bottle with water and keeping the cutting area wet will extend its life.
This made cutting our expansion lines in our concrete a piece of cake and flew right through it! I would definitely recommend it
This is the second piece of blade I bought after my first wore out. It does what it supposed to do - cutting concrete. I would recommend applying a little bit water whenever you are cutting an old, hard concrete so that it will not wear off fast.
This is a serious blade for serious work. It's a great value for the money and is consistent with the DeWalt name.
Answer: no
