6Pcs HSS Center Drill Bits Set, 1/1.5/2/2.5/3/5mm 60 Degree Lathe Mill Combined Centre Drill Countersink Bit Suitable for Positioning and Chamfering Processing

As above

Used for centre drilling....

Just as I ordered good quality has bits

These are great for working with wood

used on brass and broke upon first use. and i used the largest oneSo maybe good for Aluminium only

Up to now I've used only the small size bits and already two of the tips have broken off, one of them at first use.

Well as a toolmaker by trade these centre drills are rubbish, the cutting angles are all different and some are not centered and the grinding is rough. These are definitely no good for spotting accurately on metal.

Good product would recommend

Ottimo prodotto lo consiglio

Also ich kann es nur empfehlen, weil es für sehr genaues Bohren ist. Also auch für Bastler die mit verschiedenen Materialien arbeiten. Sehr gut 👍 👍 👍 👍 👍

De momento en aluminio perfecto. Todo apunta que en acero tendré pocos problemas. Eso si, la bolsa con las brocas está llena de las propias virutas de desbarbe de las brocas. Por lo que estan mecanizadas rápido y con pocos miramientos. De ahí su precio entiendo.

Rien à dire , fait parfaitement le travail dans l' alu

Schnelle Lieferung war alles perfekt
