Very good drill bits
Great drill bits. They cut through stainless steel very nicely if you take your time and use a cutting fluid to keep them cool. Had a minor issue with one of the bits snapping (my fault) but the seller took care of the issue immediately and was very responsive.

Very high quality drills
I am a metal worker for 23 years, hard to find any better cobalt drills. Highly recommended.

Testate su acciaio da 5mm forando con la n.4 come pilota e sembra indistruttibile, le altre più grandi le usate solo per allargare il foro. La 4,5 usata come pilota si è spaccata al solo contatto con il pezzo, alcune si sono scheggiate lateralmente, probabilmente difetti di fabbricazione. Ho contattato il fornitore che mi ha subito inviato le punte in sostituzione, solo per questo meriterebbe 10 stelle. Provate su barra in ferro da 5mm e forano come se fosse burro. Consiglio pienamente l'acquisto.

I purchased these bits sometime ok...They are very sharp and cut into any material with ease and some cutting fluid of course!! However I did break a few on a project and dulled 4 bits...I contacted costumer service and within a few days they sent me a complete replacement with no questions asked.... Best companies costumer service I dealt with in forever!! Awesomeness!!

La boite est assez qualitative et répond à ce qu'on lui demande. Les forets sont de très bonne facture et cela se confirme à l'usage. La coupe, que ce soit à l'entame ou pendant le percage, est très bonne. Il faut pour cela respecter les vitesses de perçage et parfois, l'utisation d'un lubrifiant de coupe sera nécessaire,, il serait urgent que les utilisateurs de forets sachent cela au lieu d'incriminer le foret. Un foret a casser, sans raison apparente. Après conact avec le vendeur, Stroton, un envoi de rechange m'a été envoyé très rapidement. Merci pour la réactivité et le sérieux de ce vendeur/marque.
