Hand Tap 1/2 inch G for pipes
Hand Tap 1/2 inch G DIN 5157/2 HSS Varel is a precision 2-piece set (ripper + finisher) designed for manual cutting of cylindrical pipe threads type G(BSP - British Standard Pipe) with a profile angle of 55 degrees . The tool is made of high-quality HSS high-speed steel, which provides wear resistance, dimensional stability and long service life when working in materials such as steel, brass and aluminum.
The G 1/2 inch thread is characterized by an outside diameter of 20.955 mm, in accordance with ISO 228-1. Thanks to its compliance with DIN 5157/2, the set includes two threaders - for preliminary machining (ripper) and for finishing (finisher), which allows safe and accurate threading.
The 1/2 inch pipe threader of the brand Varel will prove useful in installation, service and workshop work, wherever precision, durability and compliance with BSP pipe thread standards are required.

Frequently asked questions
1. Why is the G 1/2 inch thread cutter 20.96 mm in diameter? G 1/2 inch how much is mm? And how many cm is it?
The question "G 1/2 inch how many mm" or "G 1/2 inch how many cm" often arises when selecting tools for pipe threading. Contrary to appearances, the value of 1/2 inch(that is, 20.96 mm or 2.09 cm) does not mean the diameter of the thread, but the nominal size of the pipe to which the thread fits. In practice, a 1/2 inch G thread has an outside diameter of 20.96 mm, because G (BSP) pipe threads are designed for pipes with thick walls.
For this reason, always check the thread diameter value in the technical data, and do not convert inches directly to millimeters. In the BSP system, the thread size is a result of the design of the entire installation, not just the nominal dimension.
2. Is the G thread a tapered thread and does it provide tightness?
No. G thread (BSP) is a cylindrical pipe thread, which means that its diameter is constant along its entire length. Unlike tapered threads (designated as R or BSPT), G thread connections are not self-sealing. This means that a G thread does not provide a seal by itself - it requires an additional sealing element, such as a flat gasket, O-ring or plastic washer. Such a sealing method is commonly used in hydraulic, pneumatic and industrial installations.
