Long teeth with non iron extrusion Taps (B-EXL-NRT)
Note 1:B-EXL-NRT non ferrous alloy with long tooth extrusion screw tap.
Note 2: extrusion screw tap is the application of plastic forming method, in the next hole grinding the cut material to uplift and the formation of thread. It does not produce chips, the chip does not exist, it is also called acolpate (chip) screw. This is not because of tapping chip clogging and damage thread or wire tapping. Suitable for extrusion screw tap with thermoplastic materials such as aluminum, copper, zinc, brass and low carbon steel. Non proofreading iron by extrusion screw tap back taper has four teeth and two teeth of two. The use of extrusion screw tap, with its accuracy and selection of hole size, plastic extrusion to high precision, high quality thread; according to the material properties and coatings we have extrusion screw tap different levels of precision for customers to use.
Note 3: screw precision grade: OSG/TOSG: RH5B, RH6B, RH7B, RH8B.
Note 4: tap material: HSS-E.
Note 5: eat the inverted cone teeth number: 2 teeth (flat).
Note 6: the application of cut material: CU, BS, is suitable for copper brass brass casting BSC, Aluminum Alloy does not produce non iron material grinding chip.
