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.

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.

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.

Excellent quality and excellent price. Would definitely recommend.

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.

worked great

These drill bits work very well and the measurements are spot on. The shank on all of them are exactly 0.125” (1/8”). And the diameter of the drilling ends were all exact, according to my non-Mitutoyo calipers at least. These are much better used in a drill press of some kind because any sideways force on the smaller sized ones and they will snap. These are tungsten carbide so they are very hard and not flexible at all. I use them in a Dremel tool with the Dremel Drill Press and it works great! I think the Dremel Drill Press/Work Station thing is your best bet if you don’t already have a drill press because it’s only like $40 at the time of writing this review, and I would imagine most people already have some kind of Dremel tool if you’re looking to buy these mini drill bits. I would definitely recommend these mini drill bits to anyone needing to make very small and precise holes.

OK

A really good quality set of drills!

Sadece baskı devre çıkartmak için ideal. Herşey için geçerli değildir.

Sharp. I would imagine the 0.1mm will have little or any practical use, unless your drill is zero run-out. The. 0.3mm works fine on mine through 0.5mm brass and 2mm styrene. As a result i am confident the 0.3mm bits and larger will be fine. I have used a few of the larger bits and they are sharp. Just go easy on the smaller bits. They will snap if you apply to much force.

Llegaron justo a tiempo para cumplir con un compromiso. Excelente calidad.
