Dophee 20Pcs 0.3mm-1.6mm HSS Mini Micro Twist Precision Drill Bit Set Craft Tool + Case

0.45 drill bit missing from set and had to use screwdriver to pop open case. They are pretty much useless; it took forever to drill through plastic using a hand drill and if used a power drill you end up melting a hole instead of drilling one, they are that dull. Not worth the price.

None of them were sharpened. You not going to drill much with these.

Amazing range of very very skinny bits — most too thin for any pin vise. Packaging is inventive, but the bits have no bite.

They're is supposed to be 20 different sizes. Ranging from 0.3 - 1.6, but instead they just put in seven different sizes with multiples of the same size. If you look at the provided picture the ones that are the same length are also the same diameter. I bought these to drill some Jets out and they are useless to me. I don't have a digital caliber, so I don't know their exact diameter. I only could verify that they are same diameter, by using one to drill a hole and taking the others to match the hole. You get what you pay for sooo.... I suppose I should have known better. 😒

these drill bits are not cut properly and do not drill very well.

Almost all bits are garbage! They are not properly grinded ( one side of cutting surface grinded backwards and off center).Sizes from 0.7 to 1.6 all grinded backwards so not cutting and because one side of cutting edge is 40% shorter than opposite side - they dancing around like crazy instead of drilling. Terrible junkies.

My daughter was using these to drill holes in flat plastic beads to make curtains. She had been using a small drill bit and that worked fine until she lost it. Upon using these bits, 5 of them broke when she put any pressure on them. They are extremely weak. No pros on these. You get what you pay for.

The drills are way too thin and small to try and use them in a normal drill. The hand tool works great!
