Cobalt Metric Drill bits Set 1.5-6.5mm/13PCS High-Speed Steel Drill bit for Stainless Steel, Hard Metal, Cast Iron, Copper, Aluminum Plastic

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.

Decent set. Only used a few, but they were and still are sharp. I’d recommend

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

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

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.

Just what I was looking for. Hard to find millimeter bits

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

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.
