BAER Round Cutting Die MF 2.5 x 0.35 - HSS - tolerance 6e
BAER Round Cutting Die MF 2.5 x 0.35 - HSS - tolerance 6e
BAER dies are perfect for anyone who wants to cut 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 receive the chips, roll them and discharge them. Dies are used to cut screws, nuts and threaded rods in everyday use. The die holder is used to cut the threads by hand and with the special die holders you can also attach the round die to a tailstock or to a drill. The dies can usually be used on both sides and have a perfect cut. The tap is made of the high-speed steel HSS, which has better toughness and is less susceptible to breakage than HSSE steel. HSS steel is also a popular material for making tools that are subjected to high stresses. HSS cutting dies can be used for 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-alloyed copper and short-chipping copper-tin alloys. Also plastics such as POM, PVC etc. It is important that you lubricate the tool plumbed working and with cutting oil or cutting paste.

6e Undersize
Applications
- Undersize- tolerance: for studs that receive a surface treatment or galvanic protective layer up to approx. 8 µm layer thickness. Dies with 6e- tolerance cut approx. 0.03 mm smaller than dies with standard tolerance 6g.
- General-purpose use up to 750 N/mm²
- general structural steels, free-cutting steels, case-hardening steels and unalloyed tempering steels
- Pure copper, low-alloyed copper, as well as short-chipping copper-tin-alloys
- Plastics such as POM, PVC etc.
