Excellent. Drilled into metal box lintel with no problems or bending. Sharp and very sturdy. Says made in UK on the box, which is very rare nowadays.

Excellent value and very efficient drill bits

Excellent service and great price, only used once so far and went through like butter. Good quality.

good sharp bits no problem with these

Very good quality,don’t drill too fast and they will last for years

Well worth the money very good quality and quick delivery thank you

drills well, quality average for the price, but bits this small will break anyway

Bought these to form a pilot hole for self tapping screws. Expected to use them all but actually got the job done with only three of them. Cut really well using a drop of oil. Snapped one bit by being too heavy handed but more than happy with the quality of the drill bits.

Me van perfectas para trabajos de artesania.

Ich habe einige V2A Winkel zu bohren. Dies ging mit dem normalen HHS 3mm Bohrer absolut nicht. Der kratzte noch nicht einamal am Blech. Wogegen der HSS Cobalt flott zur Sache ging. Sehr scharf. Da ich 20 bestellt hatte werde ich wohl damit auskommen. habe erst 5 gebohrt und es geht immer noch. Aus diesem Grunde nehme ich an, dass ich noch nicht einmal 10 Bohrer brauche. Für diesen Preis! Er ist allemal 5 Sterne Wert.

el material bueno y el envio rapido

Llegaron muy rápido

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.
