Mit diesem Gewindebohrer konnte ich mein Gewinde gradeso schneiden. Er war nach dieser Anwendung auch schon nicht mehr schnittig. Er eignet sich wirklich nur für unlegierte Stähle. Den Zweiten Gewindebohrer kaufte ich nur als Reserve.

I had 60 holes to tap in 1/4" thick 304L stainless, drilled to 13/64. Not knowing how the different taps available would perform, I tried a variety, including these which were at the low end of the cost scale at $12.99 for 2 taps. I worked very slowly using plenty of thread cutting oil and found that I could cut a good thread in 20 minutes, taking only a small amount (5-10 degrees of turn) each time before reversing to cut the swarf. Despite being very careful, however, each tap just snapped without warning after forming a thread in 3.5 holes. Of the other taps I used, one cut 4.5 threads for just over twice the price then snapped, twice, whilst another cut 24 holes for just under twice the price and then the cutting edges began to break off. Each of these still took 20 minutes per hole. The final tap I tried cost quadruple the price but easily cut 20 holes taking just 5 minutes each. In summary, this tap provides a low cost option if you have just one or two holes to tap, but beyond that I would suggest getting something more durable.
