1/8 27 NPT Tapered Pipe Thread Tap High Speed Steel Pipe Thread Tap

This performed exactly as needed.

Shaft was smaller than expected so had to be extremely careful when tapping to avoid breakage.

Broke off on first use using a hand tap. Poor quality

I used this for a simple repair on an electric lamp. It worked like a charm.

While being the lowest price 1/8-27 tap on Amazon, its also better than many of the much more expensive ones because its made of High Speed Steel instead of carbon steel. High speed steel has much better resistance to heat and wear as well as being much harder than carbon steel, resulting in a tap that will cut cleaner, more consistent threads, for much longer. Taps need to be incredibly hard, much more so than most tools, and HSS in my opinion is the bare minimum when it comes to materials for taps. If you have the money, cobalt (m35, m42, etc) taps are a big step up

It does what its supposed to do.

Broke on first use returned for a full refund

very pleased! I had a steam valve that wouldnt thread into the heater due to the thread being corroded...this solved it in seconds!

IT WORKS
