    I'm not convinced its the blade that's causing the problem. What TS are you using?, fence setup etc?.

    My current aluminium cutting blade is a CMT, 235mm, triple chip grind, 6 degree neg. rake, 48 teeth. I agree with Jack that the blade you've linked to appears to be negative rake. I can't understand why you're not getting a relatively clean cut from it regardless of what you paid for it. Makes me wonder whether there is something else going on. Have you tried cutting a piece of timber with it?

    He’s using a mitre saw.

    Other possible problems? Blade on backwards. Incorrect or no arbor bushing used (assuming the arbor isn’t 30mm).

    Blade on backwards would give similar results to what he's reporting.

    When you have eliminated the impossible, whatever remains, however improbable, must be the truth, also eliminating the most obvious first is always a good place to start.

    Elementary my dear Beaver.

    It does a great job on Al and plastics. It will even cut wood - slowly and very smoothly.
    BobL,

    What sort of materials will it cut?

    I think the issue might just be the quality of the blade. $30 doesn’t get you much in a 10” aluminium blade.
    Thanks Jack, that blade should work OK. Maybe try slowing down the feed rate?

    All sorted Bob. He had the blade on backwards. So does a negative rake blade installed backwards have a positive rake?

    Blade on backwards - its not the first time this has happened - It even happened to an experienced woodie on this site who seems to have evaporated.

    Negative rake applies to the forward facing face of the tooth - when on backwards in practice it becomes a hyper negative rake which will still cut but will get super hot hence the excess galling.
