    Ok, weld up the collet, then bore it out and grind the ID to 6mm. Now you can hold a 6mm endmill in your 3/8" collet!

    Buying the correct collet is the correct answer. The sleeve can work fine, with some reduction in precision and rigidity, but will cost you more in time that the price of the correct collet. The...

    Got mine on order, thanks for bringing them up or I never would have known! Work smarter AND harder!

    My Haas has the side-mount tool changer, and I've never once gotten a chip on the taper. I let it run overnight unattended, using the tool touch-off probe to check for tool breakage after most...

    That's a good point. What's the average yearly maintenance cost on the Mori as compared to the Haas? I know of the Haas blows a spindle you can get it replaced in a couple few days for a couple few...

    You can probably use that same cutter to finish. Do small stepdowns with skim cuts and you'll get a pretty nice finish. I've got a 5/8" Helical relieved that sticks out 4" that does this on 17-4...

    Yes, but the electric "drone" configuration lends itself very well to automated piloting, which I'm sure is a big motivator towards its adoption. Prove out one part of the tech at a time.

    Personally I've never seen an endmill with eccentric flutes, but I never buy the cheapest stuff. Any reputable brand should have runout closer than you can reasonably measure. Make sure to put it...

    You can buy flat bottom drills. There are dozens if not hundreds of places that will grind a custom cutter for you too, some even at a pretty good price.
