Great for 3d printing
Bought these when i got back into 3d printing and needed to be able to precisely clearance holes in things i had printed since 99% of measurements used in 3d printing projects are metric. Well made, works well, great price, and the plastic case locks closed so you dont have to worry about them bouncing around in a bag and falling out.

Nice drill bits.
Used these to drill out some holes in 3d prints. They work as expected. Will buy again.

Look good
Can't wait to shred all the stripped out screws on my Terminator rc truck. Going to be drilling some heads off today. Lol

Hält nicht was es verspricht
Bereits beim ersten Einsatz hat es einen der dünneren Bohrer zerlegt. Die Spitze steckt im Werkstück, ein Teil im Futter der Maschine und der Rest ist weggeflogen. Richtig Vortrieb im Metall gab es auch nicht wirklich (ich wollte eine abgerissene Schraube ausbohren). Und was die 'automatischen Positionierung' sein soll, kann ich nicht nachvollziehen.
