Good value for money
Good quality bits for times when I need a metric hole for clearance or tap sizes. With proper use of cutting fluid, these have worked well and retained their sharpness.

Works perfectly
Exactly what the Dr ordered.9mm bits.

Good enough.
Small drill bits are fragile, and they'll break at some point. So when using them, never apply to much pressure.

Great on stainless steel
I do a lot of drill into thin but hard stainless steel. These stayed sharp the longest. I need the small increments of this mm set. Im happy with my purchase.

A Nice Set of Bits.
I wanted a good set of bits for my 3D prints. After scrolling through the available metric bits I decided to go with this set. And am very glad I did. You can feel the edge when handling the bits. And the storage case is very rugged thick plastic.

great deal
I had to use the drills to over size the housing

One complaint
Would probably give 5 stars but the case broke the first time I opened it. The bits work great but since the case hinge broke its a pain to shut the case every time.

The hole size I need every time
I got tired of the standard SAE drill bits because their sizes were spaced too far apart. The ones offering smaller spacing weren't easy to understand; I mean, 31/64ths? Really. Metric would be so much easier. I didn't need metric, per se, but I wanted more exactness in the holes that I drilled. You handymen and handygals know what I mean. They're very high quality and come stored in an easily accessible case.Overall, an excellent product.

Realy good quality drill bits
I made my mounting rack for my solar panels out of used steal pipe, and I had to drill quite a few holes for mounting these panels. The piping was quite hard and I bought five drill bits, so as to make sure I wouldn't run out. To my surprise the drill bits held up really well and I was able to drill all the holes with just one bit.I did pre-drill the holes with a center drill, but that was all I used, and of course some lubricant.I never thought that I could drill these many holes without wearing out the drill bit. Quite amazing.
