I have a CNC Router Job shop and also sell wood and aluminum routing tooling. I find Whiteside and Southeast Tooling to both be very wise choices for most wood applications. I sell both of these brands. I also find that Onsrud is the Cat's Meow for routing aluminum. I can resell their products also. As I use the products that I sell, I can provide real world answers to those applications where I have direct experience, or for those cases warranting the work, I can test cut customer specific combinations. I have a CNC Router with 13 Hp spindles, with useable RPM ranges from 1000 to 20000 rpm, peak torque hits at about 8000. I can test feeds to 3000 ipm, but I have yet to find a tool that can take much over 2400 ipm. As for small ball nose tools, let me know what you want specifically, and what kind of volume (number of bits you think you want at a time) and I will see what is available for you.
