15-Piece M35 Cobalt Drill Bit Set, Metric 1.5-10mm for Hard Metals

These are much better than the conventional cheap bits I'd been using -- they really cut very nicely through steel and aluminum, and even though they're not rated for it they work well on plastic and wood, too. And, they're not very expensive -- should have gotten them long ago.

These are the sharpest and Best Drill bits I have ever owned and I have bought many over the past 70 years ! They drilled out a broken screw extractor like it was nothing ! I love the case they came in which was very well made ! If I ever needed any more drill bits it would diffidently be from this fine company ! Great product at a very good price and arrived quickly!

The bits themselves are OK, but definitely not on the higher end (also much lower price than high end bits). The case is poorly molded and low quality. Next time, I'd likely elect to buy a more expensive set.

Very nice

What’s the point of having a drill set when each drill bit is +/- .5mm.. if they are going to be that far off you might as well just go up or down to the next size in a quality drill bit set

good set of smaller metric bits

As an american who deals with cad and 3d modeling, being able to use metric is a must, very difficult to find metric tools other than from online retailers as local businesses require me to order out for them and charge a premium for the privilege. Work great with aluminum, and wood (haven't tried anything harder) with minimal damage to the bit.

Problem with search for "Metric Drill Bits" on Amazon is that more than half the items coming up are NOT "Metric". Amazon has the absolute worst search engine on the internet. I ordered these to use when tapping holes for metric fasteners. Specifically I needed 5.0 mm for M6x1. I am hoping the 0.5 mm steps will get me close for other sizes as well. The drill bits seem OK but I only use them for finishing holes that have been pre-drilled with less expensive Imperial (inch) sized bits. As others have stated the case is pain ... Shirley they could do better.

These drill bits are of high quality. I struggled with titanium ones until I found these ones and was able to complete my project in 1 day.

This is the best drill bit for drilling out stainless steel screw which is very hard metal. Do not buy the titanium coated for hard steel they go blunt in second.

Excelente relación Precio -Calidad. No soy profesional sólo aficionado pero en verdad es un gusto trabajar con estas brocas. Perforan con gran facilidad como se nota en la viruta de la fotografía. Estoy utilizando solera de 1/8 de pulgada colocando dos tramos juntos al perforar. No es necesario presionar el taladro ni enfríar la broca . Las recomiendo ampliamente. Las volveré a comprar en otras medidas.

Great little drill set perfect for what I need drill some stainless steel with out any problem what so ever

muito boas
