Customer Reviews

Cuts cleanly
Not much needs to be said. This one delivers what you want in a saw blade; no noticeable vibration, cuts cleanly (top and bottom faces!), and lasts a long time considering you are essentially cutting cement and paper. Used on a 12" Bosch SCMS.

One other thing, if you are considering following the manufacturer's advice and using a power shears to cut fiber cement instead of a saw blade to minimize dust, save your money, buy a dust mask, and get this blade. The shears won't ever get you consistent edges and smooth cuts like this (I regretably wasted my money on the PC one). Also, use a sharp utility knife blade to do the 'score and snap' method for those cuts the SCMS cannot do -- and get the Malco nippers too!

Must have for Hardi-Plank siding
Title says it all. Great blades. These things slice through fiber cement siding like a hot knife through butter. VERY low dust too. Long life on blade--I did a three car garage and attached 170 sq ft mudroom on one blade with no real noticeable dulling of blade. If you were siding a whole house or larger addition, you'd probably need two blades though.

Cuts cleanly and lasts
These blades are great: clean cuts, not terribly loud, and durable. Used them on a large Hardie siding job and would use them again.
