BAER Round Cutting Die UNC 1/4 x 20 - HSS
The die is a reliable and durable tool that helps you to produce precise external threads in one operation. It is equipped with four holes and a V-groove that secure the die in matching die stock and holders. This allows you to handle the die safely and comfortably. The BAER round die is also perfect for use in a tailstock or chuck of a drill press. Dies are tools used for cutting screws, nuts and threaded rods in everyday life. Round dies are cylindrical in shape and are used for making external threads in one operation. There are four holes and a groove on the outer casing of the round die, which are used to fasten the die in suitable die holder and holders by means of retaining screws. External threads are cut by hand with die stock. Special die holders are used for the tailstock on a lathe or for the chuck of a drill. The external thread cutting tool is made of high speed steel (HSS). HSS steel has a higher toughness and a lower susceptibility to breakage compared to HSSE steel. HSS steel is known for its exceptional cutting performance and durability. HSS cutting dies can be used for a wide range of applications, such as structural steels, carbon steels and free-cutting steels. It is also suitable for case-hardening steels and unalloyed tempering steels with a strength of up to 750 N/mm². Cast steel as well as zinc alloys can also be cut with it, as well as pure copper, low-alloy copper, as well as short-chipping copper-tin alloys, plastics such as POM, PVC, etc. It is important that you lubricate the tool plumbed working and with cutting oil or cutting paste.
