Hi John,

I have found that single flute carbide cutters work better for ali. They need to be 'open architecture' to allow the chips to fly and you need air to shift the cuttings away.

I am experimenting with stiffening up my wibbly wobbly MD machine and the initial tests are good, both in terms of finish and also cutter breaking seems to less (I chewed into my first test at a far higher feed rate than ever before and the cutter did not immediately snap).

I have my Kress at full speed for most jobs.

Cheers,

Rob
