DEWALTCircular Dt1471 Saege Blade PCD 165 X 20 Mm 4Z

Works well on cement boards but soon wares down quickly but gives a smooth cut

Good blade

Awesome bit of kit. Have used this saw blade on three concrete cladding jobs and its still cutting great. A must for cladding.

Well made and fit for purpose, all the thing that I've come to expect from DeWalt. I do need to suggest not to take notice of the 1 star review by Darren A. He said it was useless and not up to the job, however after looking at his photos I believe he has installed the blade backwards in the saw. Circular saws cut in an upward direction for safety reasons.

I needed a masonry blade to fit a circular saw so that I could cut concrete backer boards. This does the job really well.

I bought this blade to cut through the Hardie board cladding on my garage.It started out very well, but was getting a bit dull by the time I had finished, so I would not say it was fantastic value for money.That said, it did the job, left a nice clean finish and so it’s done what it was sold to do, so I can’t really complain.

Absolute king for cutting cement boards

I had previously used a similar blade of another brand with good results cutting 40 or so boards with one blade no issues. This dewalt one didn't even get through a single board before the tips just snapped off and burned the blade. I wasn't forcing the blade through the board either. also this was 18mm thick rather than 22 of the previous boards. I'd say this is false advertising saying it works on cement boards.
