Fiber Cement T Shank Scroll Jigsaw Blades Set 3 Carbide Grit Jigsaw Blades T Shank for Drywall Hardie Cement Backer Board Cement Siding Jigsaw T Shank Scroll Carbide Grit Jig Saw Blades for Curve Cuts

We had to open a hole and Stucco. These drill bit cut the stucco and Hardy back, clean without any issues. The only problem is when you cut into plastic. They do Bend. I highly recommend these bits.

Absolute garbage blades! The blade material is soft you can bend the blades with your fingers. Upon use, they quickly twist and then bind in what you are cutting or shear off! DO NOT buy this product!!!!

Contrary to other comments this fits my dewalt saw and one blade has cut 2 12" sections of hardie board into 18 scallops 80 more to go. Will probably use 5 blades..go easy let the blade do the cutting.

Not a very good product in my opinion

I bought it to cut hardieback cement board made three full length cuts, two width cuts and one circle cut, still had good edge

Cuts fine, but blades are short and jams up on the 1/2 inch osb sub siding behind the hardie. I wish they were a bit longer.

Blades bent very easily which made them useless almost instantly. This may have been due to the blade shanking no fully fitting into my saw but I feel this is, at best, only partially the problem. I cannot recommended this product for cutting much else besides very soft materials.

Very inconsistent diamond coverage. I was reselling them and decided not to. Quality is sub par at best

Bought these to cut 6.00mm thick slates. Ok for first 25mm (1 inch) then blades not cutting and bending when pushing jigsaw forward. Blades must be poor quality steel and abrasive coating didn’t last. Bought Bosch stone cutting disc and used this on my angle grinder, amazing difference, cut through slate like the proverbial knife through butter. It pays to buy quality well proven makes.

I have used similar jigsaw blades to cut ceramic tiles in the past and so was very disappointed to find these were completely useless. Do not waste your money.
