Paper And Fabric Grades
For threaded holes over 1/2”, it is often more desirable to single point turn the thread.
For all other threads, standard methods are used with satisfactory results. The speed and feeds are similar to those used in threading soft steel.
Glass Base Grades
External and internal threads can be cut with a carbide-tipped tool dry. Fine cuts should be taken to give best results. A water soluble coolant can be used if finer finishes are required.
