I would like to get inside the drive and have an idea that it is a T9 or T8 size. Certainly a T10 is too large. Not sure if this is a universal size or type of bit. Having confirmed size and type, where is best place for purchase. I don't really want to buy a set. TIA
The height above the platters that the heads fly is a fraction of the size of a cigarette smoke particle - hugely less than a human hair or any other dust particle. That's why they're manufactured inside class 100 clean rooms.
