◆ STI
female thread of screw tap
sometimes, the coil is inserted after tapping, so as to increase the strength of female thread and enhance its durability. STI is the tap used to cut this female thread, and its diameter is usually increased to the same size as the coil
◆ F-SL/F-SP
Taps for high-speed cutting
Tapes for high-speed cutting are specially used for tapping machines with fully synchronous pitch pushing function. The tap for high-speed cutting is made of high-grade high-speed steel with high toughness and high wear resistance. In addition to appropriately increasing the size of its effective diameter, the surface is treated with titanium.
F-SL is a left spiral tip tap (it functions like a tip tap and discharges the cutting from below the hole). F-SP is the right spiral screw tap (like a general screw tap)
