Trex Blades Ideal for Cutting

Composite Decking and Cellular PVC

Specially designed for cutting composite material, the 12 in. x 84-Tooth Diablo TrexBlade features Modified Triple Chip Grind tooth geometry for exceptional durability in cutting highly abrasive materials. Constructed with TiCo Hi-Density special-blend carbide, this durable blade is outfitted with 84 teeth to make smooth, finely finished cuts in deck boards, giving outdoor retreats a polished look. The Perma-SHIELD non-stick coating reduces drag while stabilizer vents absorb noise and vibration to keep the blade straight. An ultra-slim kerf produces a thin cut for less material removal and fast, effortless operation.
  • Freud TiCo high-density carbide is specially formulated to maximize cutting life in composite materials and plastics
  • Modified Triple Chip Grind (MTCG) fabrication keeps composite material cool while cutting, producing melt-free cuts
  • Laser-cut stabilizer vents absorb noise and vibration, keeping the blade straight and true for superior quality cuts
  • Perma-SHIELD non-stick coating reduces drag and shields the blade against heat, gumming and corrosion
  • Super-thin kerf provides fast, clean cuts with minimal material removal, ideal for underpowered saws on a job site

    Q:Does this blade cut wood as well?

    Answer This Question

    A:  Yes it will,but of course it is made primarily for trex and composite materials.

    by|Aug 22, 2020

    A:  Yes, I'm using it on a miter saw and it cuts wood clean and easily, equal to my previous 84 tooth blade. Actually proving more durable. Key is the 84 teeth - this is more for fine cuts in lumber rather than rapid cross or rip cuts, where less teeth is the way to go.

    by|Aug 22, 2020

    A:  It will definitely cut wood but it’s not optimized for that and will result in poor performance. We have several options designed and optimized exclusively to deliver the best performance for wood cutting.

            This blade was not any better than a Dewalt blade at cutting my Trex boards. As expensive as the blade was, I expected a little better!
