• Application : زدن رزوه بر روی قطعات مختلف

• Machinery : با دسته قلاویز دستی

The M7 three-piece hand tap set has a nominal diameter of 7 millimeters and a thread pitch of 1.0 millimeter, designed according to the ISO metric standard. This set includes taper, intermediate, and bottoming taps, used respectively for starting, extending, and finishing internal threads. The thread angle is 60 degrees, and the straight or spiral flutes provide effective chip evacuation during operation. The taps are typically made from high-speed steel HSS with a surface hardness of around 62 to 65 HRC, offering high resistance to wear and stress. The overall length ranges from 50 to 70 millimeters, and the square shank is suitable for installation in a hand tap wrench.

The recommended pilot drill diameter for M7 taps is 6.0 millimeters to ensure optimal thread engagement with the workpiece. Using a three-piece set reduces the required cutting force and improves threading precision. The recommended manual tapping speed is approximately 10 to 15 revolutions per minute to prevent tool breakage. These taps are ideal for threading in low-carbon steel, aluminum, and non-ferrous metals. They are primarily used in industrial maintenance, precision mechanical part manufacturing, and low-volume custom production.
