    Cut your speed in half for starters.

    You may also need to use straight oil rather than coolant.

    +1 on this.

    If you have a long drill and don't want to spend money on a second, shorter drill, you can use an endmill and helical bore a starter hole about 1/2" deep.

    Not needed and not desirable anyway.

    Even with two inserts, they're effectively single flute and wouldn't follow a spotted hole. The center insert is usually designed to guide it in straight.

    Peck drill.

    Compared to birds nesting, it's the lesser of two evils.

    Feeding beyond the recommended parameter range isn't a real option.

    They make insert drills in increments of 0.5mm.

    Your tolerances are wide open.

    Hit it with a 33.5mm indexable in one shot and call it a day.

    Wouldn't even need the chip blaster. Haas' basic 300psi TSC pump will easily handle indexable drills in the 1" size range. 1000 psi coolant is for small tooling.

    This happens consistently or randomly? Can you easily duplicate the problem? What happens if you add a G4 P5. dwell between the two automatic cycles?

    Agreed with the others that this isn't worth the brainpower to figure out.

    +1 on this.

    One step I might add, after sawcutting, is predrilling the ID with a 1.5" indexable. Hit it from both sides so you only need a 6" drill.

    So that's going to be somewhere in the neighborhood of 350F. Not really that hot, and you could do it in a household oven.

    The CMX doesn't use CELOS. Its control is closer to the older MAPPS IV.

    Its chip control is tops for a VMC. The X-axis way covers are slanted at 45 degrees to prevent chip buildup. The spindle...

    485 SFM is pretty decent for H900 material.

    You can experiment, but expect tool life to drop off quickly past a certain point - most likely not too far off from where you're already at.

    The BRM units wear pretty well. They have short (18mm) and long (38mm) trim lengths. We use the long ones.

    Even with daily use, expected life on these is measured in years.

    Tap water and dish detergent aren't going to clean the parts very well anyway. It'll probably leave a lot of streaks.
