Very good quality drill bits at a fantastic price. I bought these to drill several holes into some thick steel thinking I would get through several but completed the job with the first one.

Super Qualität
Habe 10 Bohrer für 100 Löcher bestellt. Habe nur einen Bohrer in 1,5 verzinktes Blech gebraucht. Die Zentrierung ist perfekt. Kein Weglaufen des Bohrers. Tolles Produkt! Würde ich von der Firma jederzeit wieder kaufen.

Material dúctil
Taladrando en aluminio rompí 3 brocas en unas 2 horas. Corta bien pero el material es dúctil, se doblan mucho con la presión necesaria y rompen muy fácil. Compré en la ferretería ese día unas brocas marca Izar y no se me han roto tras días de taladrado con ellas.
