Composite Decking

[Birdhunter]

i am repairing some outdoor fixtures for my club. The original structure was made of pressure treated 2X6 boards. Boards that lay essentially flat have rotted. i am using composite boards 1X6 to replace the rotted boards.

Home Depot refused to cut the boards saying their saw blades would be ruined. i had a Festool jigsaw with me so was able to cut the boards down to where they would fit in my SUV.

I called Forrest (I use their blades). They recommended using a cheap throwaway blade.

It surprised me that the composite decking would ruin a high quality carbide blade.

I cut a bunch of composite decking recently. I didn’t notice any issue with my blades. Used a Dewalt 6 1/2” blade on my cordless circular and a Diablo 10” blade on the chopsaw.

Cutting composite decking does dull a carbide blade much faster than cutting natural wood but it doesn’t ruin the blade.

Interesting thread......

It has been a couple of years since I did a composite deck, but in the course of that deck I had to rip a bunch of boards using my TS-55.

Yes, the material did dull the blade faster than wood have, but I managed to power thru at a much slower rate towards the end of the project.

The blade didn't appear to be damaged but is in the pile to send out for sharpening.

Likewise my Diablo blade was on the ‘needs a sharpen’ pile after the composite until I dropped it and broke 2 teeth off….
