Adolfo C.Adolfo C.: The media could not be loaded. I only used 1 of the drill bits to make pilot holes for a deck I was building. With a jig I created it prevented the bit was flexing.

penname: drill through wood fast, but will dull if you hit a metal or nail about 3 times. It can be re-sharpened with a sharpener, but it will cost you time. I reconment a more expensive Colbalt drill bit.

EdJ: The drill bits had quite lot a of machine oil covering them and the plastic pouch they are stored in. I really didn't mind since it was easy to wipe down. The light coating that remains will help keep the rust at bay.
The bits were also straight and the one I have used so far made short work of drilling out a 6" 3D printed cylinder. I'm happy with these so far.

An average Diy user: Bought similar before which turned out to be of poor quality. I've used a couple of the smaller sizes and so far...so good. Just don't put too much pressure on them and clear the hole out whilst drilling.

Frank: Die Bohrer habe ich benötigt, um für Stockschrauben 8cm tiefe Löcher in Dachbalken vorzubohren. Der Vortrieb in Weichholz (Nadelholz) war gut bis sehr gut. Dazu wurde ein Akkuschrauber bei mittlerer Drehzahl verwendet.
Die verwendeten Bohrer sind alle rund gelaufen. Bei langen dünnen Bohrern sollte die Bohrmaschine natürlich sehr ruhig gehalten und nicht mit Gewalt gedrückt werden.
Langzeiterfahrungen habe ich noch nicht, da ich die Bohrer nur gelegentlich benötige. Für meine Zwecke waren sie bisher völlig ausreichend und ich würde sie wieder kaufen.

valentino vivarelli: Per come sono realizzate sono ok anche per il legno considerato che, oltretutto, per il legno certe misure( quelle piccole) non si trovano...
