"Nice sharp and well finished cutting surfaces on both pieces. It did well for chasing out a spark plug hole and cleaning up threads. I did not purchase it for do repeat cuts or as a production tool so it worked perfectly for my needs."

Got these for my brother after months of hardcore use, the tapered one snapped but the other one has since been welded to a socket so he could use a ratchet or drill with proper adapter. A 1/2 drive socket at that and still using it today. Were bought about 6 months agofrank george espinal

Compré el Aceteel M12 x 1.0 mano métrica (rosca derecha) y la verdad superó mis expectativas. La rosca está perfectamente mecanizada, con cortes limpios y precisos, lo que permite un trabajo suave y sin trabas al momento de hacer el roscado.El material se siente resistente y de buena calidad, ideal para trabajos mecánicos que requieren exactitud. Lo utilicé en acero y el resultado fue excelente, logrando una rosca uniforme y bien definida desde la primera pasada.Además, el paquete viene con el par completo, lo que lo hace aún más conveniente. Sin duda, una muy buena relación calidad-precio. Lo volvería a comprar sin pensarlo.works great on my rebel 250 didnt have to take a link out or anything gave me a better top speed just made the gears feel longer didnt loose acceleration i recommend pairing it with a 15t sprocket up front

these are actually really nice taps, i used them on my mk1 gtis lug nut holes the threads where destroyed almost completely flat but this cut fresh threads into them and i got to use the same size but new lug nuts, not having to drill it out and go to a bigger size because of the tapered edge when using the first tap helps a lottm

Decent, cheap, worked for threading 3D prints. I did notice the holes were a little too big, though, so ordered another tap with tighter tolerance. I did not even realize taps had tolerances, but they do. Look it up. This one had no "H" rating that I could find -- my best estimate is that it is an between an H6 and H8.nicole johnson
