Excellent value.
These are excellent for my hobby of plastic model building. They are very accurately ground, and cut cleanly when chucked in a pin vice using very slow rotation. They need just the lightest pressure to begin cutting in polystyrene plastic. The smallest are very fragile, as is to be expected, and need the swarf clearing frequently which is why I'm now on my second order. The very reasonable price, however, makes this wastage acceptable. They're amazing value.

Useful tools
Neatly presented in good strong storage cases. It would be useful if the drill sizes were marked either on the case or the collar.

Great small drills
Great set, the drills are fragile but at this size you can not help that.The colour coding is a nice touch, so far i have used with no breakages and the drills have seemed sharp.The storge boxes are also apricated ensuring everything stays safe between uses.

NOT 3mm shanks!
These are good quality drills,though of course you have to be careful not to break them.BUT! They are not on 3mm shanks,but on 3.1mm or 1/8" so didn't fit my micro drill.

Love these little bits
Really happy with these bits, as they fit in my drill chuck so I don’t have to get my dremel out every time I want to drill a quick (tiny) hole. Yes, they break, but that’s to be expected of something of this size.

Broken bits
Although these bits come in cases, when they arrived ( I'd order multiple packs) I found that a number of bits had come loose during transit and a number of them had snapped along with a couple of them actually embedded in the plastic case they store in! I'm not suggesting the bits are low quality as they are very fine and delicate, but the packaging is a little to be desired judging by the damage that resulted upon opening.
