Best bits I've ever used! On stainless too!
Incredible drill bits. 9 holes in stainless steel 12mm on one single bit! Best drill bits ive ever used. Better than bosch even! Well done it's nice to see a British company being the best.

Perfect for the job
Essentially I needed to drill small holes in metal plates for work, sometimes the steel can be quite hard. Many drill bits don't last very long or struggle to even make an impression. These are proving very effective and well up to the job so I'm sure I will be ordering more in due course. Really good value too, I can certainly recommend them to anyone.

Quality product
Bought several years ago. Excellent product, mainly used for pilot holes. Lost them before they worn down so bought another pack of 10. I iamgine theyll be as good. Looked like 2 were missing but gave the pack a shake (before opening) and the others appeared, hidden behind others bits.

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.

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.
