    Great Finish

    At least for the woodworking that I do, I could not ask for better. The blades are super sharp and durable, they can be rotated, which provides for longevity, this thing hogs off material and most importantly it leaves a great finish. Depending on what Im making, I have even skipped sanding afterwards.

    Smooth as glass

    Though I got this to plane my CNC spoil board I found myself having to use this on some lumber, and the finish was glass smooth. Even made curled shavings not unlike my hand planes.

    Far superior to any others I’ve tried

    All the other bits I’ve tried resulted in burning and uneven passes, but this bit is sharp and leaves a perfect finish

    Brillant.

    It was giving me clean cuts to level a table. It is super sharp though, slipped while attaching and had to tape up a slight wound! Classic user error.
