Yuhtech 5Pcs Steel BSP 55 Degree Hand Taper Pipe Thread Tap G1/8 G1/4 G3/8 G1/2 G3/4

Do the job, well enough made I use them for cleaning threads on differential sump plugs etc correct pitches and dimensions.

Bit on the rough side, for a quick repair is ok but the threading leaves a bit to be desired; you'll need a good cutting paste to clean the treads.

Unfortunately I am only able to give these 4 stars not 5 as they became blunt quit fast although I was tapping 316 stainless steel. But no snapping or any problems other than that.

Well made product with good price and qualityFinnish.

Does the job if you have one thread to tap, even with the correct sized hole drilled, the tap has difficulty even starting.My advice is find a better product.

does exactly what they are designed for

worked well but not used on any hard materials therefore cannot give the set 5 stars at this point.

These are parallel thread taps. I could not use them to determine quality but the fact that they are shipped loose together in one plastic bag means that even if they were sharp when manufactured, they are likely to be blunt by the time they arrive with the customer.
