Frequently Asked Questions

Q: What is a BSP taper pipe tap used for?

A: A BSP (British Standard Pipe) taper pipe tap is used to cut internal threads in metal workpieces so that BSP-threaded pipe fittings can be screwed in securely. It is commonly used in plumbing, pneumatic systems, hydraulic assemblies, and general metalworking applications where a leak-resistant tapered thread connection is required.

Q: What drill bit size should I use before tapping with this tool?

A: Each BSP size requires a specific pilot hole: 1/8" → 8.8mm, 1/4" → 11.7mm, 3/8" → 15.2mm, 1/2" → 18.9mm, and 3/4" → 24.4mm. Always drill the correct pilot hole size first to ensure clean, accurate threads and to prevent tap breakage.

Q: What metals can this pipe tap cut threads in?

A: This straight-flute taper tap is suitable for threading a wide range of machinable metals including mild steel, aluminum, brass, copper, and cast iron. For best results, use a cutting fluid or tapping oil to extend tool life and improve thread quality.

Q: Is this tap sold as a set or individually?

A: Each order includes 1 piece. You can select the specific BSP size you need (1/8", 1/4", 3/8", 1/2", or 3/4") from the available options at the time of purchase.
