OriGlam 1/4" BSP Pipe Tap, Thread Forming Taps, G1/4 Pipe taps Threading Taps for Clean & Re-thread Damaged/Jam Pipe Threads

For light duty tapping and clean-up, at this price range, the quality is better than average. I used it for a liquid cooling install for a PC.

Did the job for the one BSP thread I had to chase. I don't know how long it would hold up if you used it a lot but it was fine at least once. :)

Threads are cut properly. Overall sharp. However the tap is 0.005” too large in diameter. As such it is a paperweight.

Product appeared to be used, very dirty and burrs were rolled over. After cleaning up the burrs the tap wouldn't screw into an existing nut that was the proper size. Measured diameter with a micrometer and found it to be .015 oversize. Not worth the hassle of returning, will try another supplier. Buyer beware!
