1.5mm-6.5mm

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.

Sharp. Nice index. Almost impossible to find metric drills here in the states. So a win all around.

Solid drill bits. Great cut and very sharp. Not made for heavy use. Good value for the money.

I wanted some metric bits, and these guys are very tough, able to go through steel with no problem whatsoever. They are also sharp enough to cut through metal and plastic, as well as wood. They're a great deal, and I am happy to have bought them.

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

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

I'm super-happy with these bits. They are very high quality and very sharp.

very sharp drills. nice set in a carrying case that keeps them organized very neatly. now I don't need to rumnage through all my tools to find one drill that works. great product

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.
