Document: It was not what I was looking for,I need tool that will take thicker drills.I drill holes on CDs,hard plastic etc. this will not work will find some use to use. Thanks
The drill I received came with a very poor collett. The slots and hole were cut off center. It is very hard to drill a hole when the bit is not in the center. It wants to wobble all over instead of spinning nicely. The bits work pretty good but, the case is terrible. It is very hard to get open and then I couldn't get it to close all the way. The smallest bit keeps falling out the access hole.
I enjoy making jewelry and am working with pearls. The holes were too small to get the chain thru and the drill I had purchased, well, the bits were too big. I have had extreme satisfaction with this small drill. One has to be careful in using the bits b/c they are a little fragile, giving their small size. Excellent purchase and I have purchased two! Has really simplified my work and decreased my stress!! !
I hate to be harsh but this set is pretty useless. I wanted this set to work on my model horses. (Drill holes to insert wires for tails, insert wings, horns, etc.) I was looking for a tool that would be quicker and easier then setting up my dremmel to drill just a single small hole. I was excited to get it for Christmas but immediately noticed how incredibly tiny the bits were! I didn't even know they could make drill bits this small!
Drills are perfect for those super tiny jobs... The case is a little on the hard side to get open and it takes some work to not lose them all on the floor, First time I opened it, I dropped about half of the set on the carpet! Took me a while on my hands and knees with a bright light, but I did find them all!!! With use it does start to open easier.
I wasn't sure what I was going to do with these bits, but the idea of drilling sub-millimeter diameter holes in my models and other projects appealed to me in general. The price seemed more than fair at Amazon so I took a chance.The Bits: I break 1 or 2 bits for each hole and I take a painstakingly long time to drill, twisting slowly and barely using any pressure.
I also assumed from the picture that the drill tip was designed to spin independently of the blue part. Not the case. Nothing spins freely, making precise work awkward. The x shaped tip where the bit is placed is not precisely cut, and the bits have a hard time fitting. So even at that six bucks I feel a bit ripped off.
(Trying to press too hard *will* lead to snapped bits, irritation, drill slips & scratches, and the grave possibility you will teach your 4 year old colorful new words. Which they will not repeat until you are either at church, at a work-related event, or standing next to them while talking to their teacher/principal (or your boss).)
Forget it for any metal. You do get a bunch of drills (as they break fairly easily), so, for the money, I think it is worth it. It all depends on your purpose, for soft things to puncture, it is pretty good, for hard things like metal or hard woods, unless you have a drill that will actually hold the little drill bit in place, I don't think it is functional.
I do strongly recommend using the dremmel drill press for this kind of work as the bits are as fragile as glass and will break at the slightest side pressure as all these tiny ones will. I cut 15 holes to a depth of 1/2" with the #71 yesterday, and it is still sharp and capable of several more holes. The plastic index the bits come in is not hardly usable due to alot of flash, and a general poor fit,  but it does keep the bits secure.
Answer: yes
