MACHO MÁQUINA DIN 376B HSS M30X3,5MM

CHEMITOOL machine taps made of high-speed steel, manufactured in accordance with DIN 376 in B form, are specially designed for demanding jobs, given their reinforced fit in order to provide the user with a good quality product with a constant work output during the tapping process.
CHEMITOOL machine taps in form B require a high torque, with low threading pressure, achieving a better surface finish.In the DIN 376 version, it is specially developed for opening threads where there is no exit in the material. This type of threading/drilling is called “blind drilling”.
In HSS-G M2 (blue ring), it can be used on steel and non-ferrous metals with a hardness of 800 N/mm2.
The thread pitches of the machine taps comply with tolerance class 6H.Metric machine taps have a square-shaped insert (according to DIN 10), to be firmly held in the power tool adjusted for this purpose, thus preventing springing when torsional forces are being exerted.
