40Pcs PCB Micro Drill Bits Set, 0.1mm-1.0mm, Shank Spiral Tungsten Steel Carbide PCB Print Circuit Board Flute CNC Router Bits for Print Rough Stone Circuit Board Jewelry CNC Engraving

Good precision drill bits used for model making. Obviously being so thin they will be weak and break if not used correctly.

Brilliant, easy to use and still going strong after many uses

ideal for small jobs

After buying micro drills, and finding time and time again that they were blunt and wouldn't drill, I discovered these. Brilliant! These have been properly sharpened. I only use them to drill wood so I can't comment on their use in other materials but what a relief to find micro drills that can actually drill. Be warned though, they are brittle and will snap if abused but with care will last me for a long time. And at this quantity and price, V.F.M. So well pleased with my purchase.

Good set of micro drill bits. Sharp and work well on hardwoods. Good storage boxes too.

Not so durable

Brake far to easy even with no pressure and do not drill the best when thay don't snap avoid

Ideal for small scale model making . Competitive price

Great drill bits. Nice and sharp. Great for plastic model kits. Just be careful with the thin ones.

Forunis en 4 exemplaires pour chaque taille (intéressant, car c'est assez fragile) pour un prix raisonnable, la taille est identifiée par une bague colorée. Ils percent bien le bois et le métal, avec une tige de 3mm de diamètre, ce qui permet de les utiliser sans mandrin spécial. Un bon achat, que je recommande...

Excelente producto, varios tamaños de brocas, incluído para gas lp y natural

Perfektes Set an Kleinstbohrer

Einfach aber von guter Qualität
