Comments

Dave: Could do with markings as to drill size, you have to measure each one to find the one you want.

fulfordsj: These work very well in a pin vise for use will plastic and resin miniatures. A few of the small bits broke trying the drill plastic.

ScottWing: The bits seem decently made but have a couple issues. First, one bit, .2mm, arrived broken. Must have been done at the factory as the plastic container was undamaged. Second, you need a lighted magnifying glass the read the size markings as they are very small and light.

Update 5/18/23. Sainsmart customer service contacted me about a day after I submitted the original review above. They have offered both a refund or replacement of the complete set with me keeping the original set. I declined their offers as I didn't really think it necessary since I am unlikely to ever use the broken bit. Based on their service. I would definitely order from Sainsmart again.

James Bryant: 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.

MaurizioMaurizio: Arrivate in confezione adeguata, tagliano molto bene.
Unica pecca, non c'è nell'alloggiamento della punta la misura, è scritta sulla punta stessa ma per chi come me ci vede poco è scomoda.
Per il resto consigliato.

hiden: 30本セットでこの値段は安いかなと。
一本一本にドリルの径が書いてあることを期待していましたが、それは書かれていませんでした。

Sven-Olof Eriksson: Använd med försiktighet,mycket lätt att bryta av borren.Exctrem försiktighet om eldriven maskin används.

Amazon Customer: These bits are way better than the ones that came with my pin vice. They are very sharp and cut resin efficiently. The fine wire bits are very fragile so use in some sort of drill press in order to make sure you don’t bend them. The thicker sizes seem to be decently durable.

United States on Jul 11, 2022

Charles Platt: Be prepared to do some homework. The bits are color-coded, but I find no key to tell you what each color means in mm. You'll have to match them against the photograph on the seller's Amazon page. Or, you can use a micrometer, but my micrometer is only calibrated in inches.

The thirty bits are cased in groups of ten, but the plastic cases are difficult to open, and are--well, cheap, which is unsurprising in view of the low cost of this assortment.
