Mia V. ★★★★★

Finally, a set of pre-sharpened bits that actually cut cleanly right out of the case. The 55 and 60 degree ends on each bit save a ton of setup time when switching between metric and standard threads.

Daniel ★★★★★

Cut both internal and external threads on a steel rod without any chatter thanks to the pre-sharpened 60-degree ends. The center gage made aligning the tool surprisingly easy.

Grace ★★★★★

Cut a clean 60-degree thread on my first try with the pre-sharpened bit, and the center gage made setup dead simple. Fits perfectly in my tool holder and feels solid for the price.
