    • Let me tell you about great customer SERVICE.
Size: 0.1mm - 3.0mm
Below you'll be able to read my old review. But let me tell you this company reached out right away and without asking me any questions basically said hi here's a set of are slightly more expensive bits would you like a set and they sent them to me no problem whatsoever it's 10 bits and these are hardened differently bits pretty sure I got them pretty quickly and immediately sort of testing them and when you if you read the old review you'll understand how I test my bits but because I wanted to see how good these were I push them four times tougher on the first cut with every one of those bits I pushed. I can say not one bit broke not one bit chipped not one bit even lost a little bit of color and yes I'm still operating at slow speeds to test them but it's now been a couple of weeks I've done a few things and a couple of those bits become my go-to for dealing with specific speeds that are a little bit higher than I might normally like but I'm using all the bits now and I should say that aside from the original bits that broke in which again if you read the old review you'll you'll see I haven't had any other bits from this company break just outstanding. Old review Used with feed rate of 50mm (super slow on my CnC) and right away to bits broke as spindle spun up to speed and started first cut. No other bits either bigger or smaller have broken since, but obviously some flaws in manufacturing of these bits. ... show more

    • A cost effective solution
Size: 0.1mm - 3.0mm
I do a lot of detailed modeling. From time to time I need a really small drill bit. This set includes some extremely small sizes. The very smallest one is so small that it breaks very easily, but given how small it is, I really don't see any way around that. These really come in handy, and if I do end up breaking a few of them, I'd happily buy another set. ... show more

    • Perfect for plastic model building
Size: 0.1mm - 3.0mm
I love these for a whole lot of reasons. They are very sharp, and cut plastic easily. They are inexpensive, and come in many sizes. They all have the same size shank, so I can easily swap them through my pin vice without having to change adapters. The bad? They are very brittle, a consequence of the hardness that makes them sharp. The bits don't stand up well to drops or getting bound up in media. I have snapped some drilling into white metal miniatures, but they are not really made for that, either. If you are a model builder or mini painter I consider these a must have. ... show more

    • Not for hard metal
Size: 0.1mm - 3.0mm
I think this would do very good for arts and craft. The labeling of the sizes unfortunately is nonexistent. I bought them for one specific size to try to drill through a brass orifice. Trying to drill through brass with these will not work. I broke multiples of them. However, if it was a soft metal or beads, I think it would work very good just not for hard metals. ... show more

    • Great for Scale Models, but Brittle
Size: 0.1mm - 3.0mm
I got a set of PCB drills included with a pin vise I bought earlier this year, and overall these have come to replace my standard steel drill bits for most model work. For someone who primarily works with plastic, specifically polystyrene, these things cut through it like it's barely even there! A word of warning, especially for those of you who have unsteady hands; these bits are extremely brittle, especially when going below 1mm, but that does mean that the material is extremely hard and likely keeps an edge much better than standard bits would if you don't snap them. ... show more

    • Fragile
Size: 0.1mm - 3.0mm
I currently use them for scale plastic modelling in a pin vise. The smaller bits are easy to break if not careful, Had some bits break off into the part I was working on. Other then that they work great for my use.
