The mini metric are mainly used for clocks, watches, low hardness wood and soft metal hole processing. 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 degree and keep stable. 4. Tapping depth should not exceed times the diameter of the tap: For example: diameter of about, the depth should not exceed.Less
