This end mill blew me away. I was able to make clean passes through hardened 420 stainless steel with no chipping. Since we're manufacturing for medical devices we can't use coolants since we dont have a proper method of cleaning the parts. Even with no coolant the chip formation/color was perfect. Worked just as well as my higher priced end mills.
