UNF 7/16-20 inch unified left annealer
UNF7/16-20 UNF unified left for cutting external threads. UNF, circular tool for cutting American unified external threads. These are left-hand threads LH, type UNF 7/16-20. UNF 7/16-20 chasers were produced by the Polish company FANAR, in accordance with the dimensional standard DIN 22568. For the production of tools was used special molybdenum high-speed steel HSS 800. This steel is characterized by increased strength for very difficult working conditions. It allows machining of very hard and hard-to-machine materials: steels with toughness up to 800 MPa, unalloyed structural steels, metals, aluminum, copper, bronze, brass.
Unlike conventional tool steel, dies produced from HSS are very resistant to harsh machining conditions, allow threading at very high speeds, during which high temperatures are generated (even d 600 degrees). Their blades are resistant to breakage, chipping cracks and other types of mechanical damage, which allows for long service life and lower labor costs.
