First time running the BAP300r in aluminum. Also not using N type inserts for aluminum. Running 3 thou IPT but looking up seems I can go up to 7 thou. At 24k rpm that would be 4200mm/min. I'm getting my speeds and feeds from my tool I've been making in the evening. It can input and output both imperial and metric values as I'm finding alot of useful values for SFM and IPT are in imperial but I'm running my machine in metric.
