The 1/8 ball mill and end mill bits I have are about 1.5" long. I am about to do a 3D cut that is a bit deep and I’m concerned that when I cut out the profile that the bits will be too short and allow the base of my collet to rub on the material that’s located on the sides. Are there longer 1/8 bits out there? I haven’t had much luck finding anything. What are people using for 1/8 bits for 3D cuts? Right now I am using the ones from the Sienci Store.
