1" x 11 BSPT Taper HSS Tap

 1" x 11 BSPT Taper HSS Tap - Goliath

Used on my aluminium boat

This is the tap you use when you need to cut proper tapered threads for pipe fittings.

I use taps like this when working with fittings where you need a tight, sealed connection — especially in fabrication jobs involving air, water, or fuel systems. The tapered thread means it tightens as you go, giving you a secure fit without relying on just the fitting itself.

If you’re doing any kind of pipe threading, this is a must-have tool.

What I use it for:

• Cutting BSPT tapered threads

• Pipe fittings and threaded connections

• Fabrication work requiring sealed joins

• Repairing or re-threading damaged holes

 Details:

• Size: 1” x 11 BSPT

• Type: Taper tap

• Material: HSS (High Speed Steel)

• Suitable for hand or machine use

 Why I rate it:

A proper taper tap cuts clean, accurate threads that seal properly. Cheap or worn taps can tear material and cause leaks — this gives you a clean, reliable result.

 Real workshop tip:

Use cutting fluid and take your time — back the tap off regularly to clear chips and avoid snapping it.
