BAER Round Cutting Die MF 70 x 3.0 - HSS
BAER Round Cutting Die MF 70 x 3.0 - HSS
BAER thread cutting dies are threading tools that are perfect for external threads. Basically, this cutting tool is cylindrical and has - depending on the size - three or more cutting edges inside. The holes between the cutting edges take up the chips, roll them and carry them away. Dies are commonly used in everyday life to make screws, nuts and threaded rods. Round dies are cylindrical and are used to make 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 matching die stock and holders using 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.
