Why Choose an HSS Taper Pipe Tap?
High Speed Steel taps maintain their cutting edge even under the friction and heat of metal threading. The taper geometry distributes cutting load gradually across the first few threads, reducing the risk of breakage and producing clean, accurate threads. Whether you're creating new pipe connections, repairing stripped threads, or working on hydraulic systems, this BSP taper tap delivers professional results.

Frequently Asked Questions
Q: What does a BSP Taper Pipe Tap do?
A: A BSP (British Standard Pipe) Taper Pipe Tap is used to cut internal tapered threads into a pre-drilled hole in metal. These threads are designed to accept BSP-standard pipe fittings, creating a secure and leak-resistant connection commonly used in plumbing, hydraulics, and pneumatic systems.
Q: What metals can this HSS Taper Pipe Tap cut threads in?
A: Made from High Speed Steel (HSS), this taper pipe tap is suitable for threading a wide range of metals including mild steel, cast iron, copper, brass, and aluminium. HSS maintains its hardness and cutting edge even when working through tougher materials.
Q: What size drill bit should I use before tapping with this tool?
A: You should drill a tapping (clearance) hole before using any pipe tap. The correct drill size depends on the tap size: for example, G1/8 typically requires an 8.8mm drill, G1/4 requires 11.5mm, G3/8 requires 14.5mm, G1/2 requires 18.5mm, and G3/4 requires 24.0mm. Always consult a BSP tap drill size chart for precise guidance.
Q: Do I need a special wrench to use this pipe tap?
A: No special tool is required. This HSS Taper Pipe Tap is compatible with any standard tap wrench or adjustable tap holder, which provides the leverage needed to cut clean threads smoothly and evenly through metal.
