Features:
Taper cutting edges and M7 diameter straight threaded flute.
Used with some cutting fluid or keep it wet when tapping, the will last longer.
Suit for machine use to cut thread inside hole, creating a female surface which functions like a nut.
Taper offer a very gradual cutting action, is most often used when tapping material is difficult to work (e.g. alloy steel).

Tips:
1. Recommended hardness of tapping material is not too high: Suitable for most metals, iron plate, copper, zinc, alloy steel, abrasive steel, A3 steel, stainless steel, etc.. Appropriate addition of coolant (e.g., water) can extend the service life when tapping.
2. Please control speed according to material hardness. The higher the hardness, the slower the speed. Fast speed with small torque; slow speed with high torque. The force must be uniform in tapping operations.
3. First drill the hole with twist drill, and then use the taps tapping. Tapping angle should be vertical 90 degree and keep stable.
4. Tapping depth should not exceed 1.5 times the diameter of the tap: For example: diameter of M5x0.8 about 5mm, the depth should not exceed 7.5mm.
