Reamers
MSI makes special to print reamers from HSS, Carbide, & PCD. In the photo below you can see examples of straight shank, threaded adapted, piloted, stepped and two piece (number 5 from left) reamers. The two piece reamer has a removable pilot and can be driven from the top or bottom. We can hold lip heights to or less than .0005.
