Thank you for your question. No, the A-93681 10" 80T Micro-Polished Miter Saw Blade is not intended for metal cutting. Please the Metal cutting blade options at https://www.makitatools.com/products/search/metal-cutting-blade.
Yes and no. What "can" be done and what SHOULD be done are different. I have cut many pieces of pvc, vinyl, and THIN (less than 1/16" metal) with blades like this easily. So Yes it probably can cut 1/8" flat steel if you flip the blade to turn backwards and go very very slowly. It will be extremely loud, very slow, probably dangerous, and will ruin the blade in a day. The blade isn't made for that type of cutting and you should just buy a metal cutting blade for your application which will work MUCH faster and be MUCH cheaper than this anyway. Final answer: NO. Dont use this blade for 1/8" steel.
Makita doesn't publish the hook angle for this blade, Part No. A-93681. They do make another line of miter saw blades (Makita Max Efficiency), and that line's 10", 80 teeth blade (Part No. B-66977) has a 10 degree hook angle.
I don't have personal experience cutting those materials with this blade, but I would expect that it is well suited to cut those materials, and would purchase it for those purposes. This is a well-engineered blade. More teeth = finer cuts.
I don't have personal experience using this blade to cut laminate flooring, but I would purchase this blade for that purpose. Good rule-of-thumb is: More teeth yield finer cuts. This blade cuts poplar moulding trim precisely and easily. It should work well with laminate. Also, using a carbide-tipped blade is essential for cutting laminate and harder materials. This blade is carbide-coated. It will cut well when new and will dull over time. These blades can be sharpened numerous times. I would suggest allowing the saw to reach maximum speed before cutting relatively slowly and steadily.
Thank you for your question, but we will require more specific information in order to provide an answer. Call the Makita Call Center during business hours at (800)4-MAKITA, they’re based in Buford, GA and are ready to help.
Composite decking, or engineered wood, is in the class of a harder material to cut with miter saws. That means you need to use a blade that has carbide teeth (this one does), and a greater number of teeth, rather than fewer. This blade will cut composite decking quite cleanly when relatively new (provided that a 10" saw is the appropriate size of saw to cut the particular width of decking planks you need to cut). Bear in mind that any blade will dull over time. Wear factors are frequency of use and the hardness of the materials being cut. They can be resharpened several times.
Based on the fact that he states the blade arrived warped, I am not surprised that it was making more noise. A warped blade will rub the sides (of the warped area) causing friction noise. He should have had the blade replaced before making the review...
