    What depth of cut are you running at? Trespa is hard, and I've never cut it that fast, and not very often.

    Maybe an Onsrud 68-200 series? I have one, but have never used it.

    I think the PCD as configured may shatter at high speeds... you'd have to check if your parameters put you within the recommended max SFM for the tool.

    Check out Onsrud 67-225 which is PCD with a progressive chipbreaker geometry, 3 flute.
