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

Worked perfect for what I needed it for.

Cut clean threads that sealed on a 150 psi air compressor

While being the lowest price 1/8-27 tap on Amazon, it's also better than many of the much more expensive ones because it's 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

I have a 20 year old craftsman tap and die set, USA made from carbon steel. I thought I would have to shorten the tap, but didn't want to mess up the one out of my expensive set. This hss tap cuts far easier than the carbon steel taps. Back then, I figured the cman set would be fine for occasional tapping needs and it had all of the sizes but it has been a let down. For the sizes I use most often, I have purchased noresman/viking taps, but it takes a while to get those. This was available quickly and got the oddball job done.

I was replacing the whole part before I was told about this product! What a great tool for a power washing company and anyone really

ok

This Tap saved me from having to replace a marine generator cooling manifold which had a zinc lodged in the opening due to corrosion. I re-taped the opening (chased the threads) and am good as new. Well worth the money.

Attached it to my drill and it saved me $2,000 having to buy new air struts since mine were stripped.. Very durable too I dropped it twice on concrete and threads had no visible damage.
