There are many blades designed to cut fiber-cement on the market. Why is the HardieBlade saw blade better?
The HardieBlade saw blade has been designed specifically for James Hardie fiber cement. Testing to date appears to suggest that a saw blade designed with fewer teeth generally creates larger dust particles (greater than 10 microns in diameter), thereby reducing the amount of smaller, respirable dust generated and reducing the risk for high exposures of respirable silica. On the other side, testing also suggests that masonry-type blades (such as continuous or segmented diamond rim blades) and abrasive blades are designed differently and create more respirable dust. As a rule of thumb, less teeth equates to lower respirable silica exposures.
