Reddit reviews ZJchao 10 pieces Tungsten Carbide Rotary Burr SET 1/8" shank [Misc.]

Dremel is a name brand for hand held rotary tools. I have and have had several so I will give you my .02

Vacuum powered - You connect it to a shop vac or other vacuum and the suction powers it, while this may sound good on the surface I can't see this having anykind of power from this I suggest avoiding it.

Cordless - Battery powered, I have had several. You get less torque than with a corded version, and they run down. I do have their new micro version and I like it so far, but cordless will always be a balance between power and battery life.

Corded - Best bet IMHO, get more features for less money than with the cordless and do not have to worry about waiting for one to charge.

Suggested Features -

• Do not stick with a single speed version, go with variable speed. In fact the more speed options the better IMHO. Different bits require different speeds, for example a cutting bit needs to run quicker than a wire brush.
  
  
• Multi Tool chuck - Some bits come in different diamters, this one will take them all. I love this and have replaced the old style chuck on all of my units.
  
  Bits - This will depend on what you want to use it for. I use my Dremels for everything from mixing epoxy to cutting and sanding everything (metal, wood, foam, fiberglass, etc). You can get more for your money if you buy a family of bits in a kit (example) but a few bits I have found most useful are:
  
  
• Sanding drum - then you buy the different sleves that slide over the tip and come in different grits. Again look for kits.
  
  
• Cut off disk - Go for the re-enforced ones like this
  
  
• carbide disk - Love this thing it cuts wood and softer material very well.
  
  
• carbide bits Come in many shapes and sizes, I find that they work well for shaping wood and softer materials.
  
  NOTE Like most power tools, a rotary tool takes a bit of practice, they can get away from you and eat up material (including your jeans and leg) if you are not careful. I have found that 90 percent of the time a light touch.. pull back.. and light touch.. pull back is the best method.
  
  edit: spelling and format
  

You'll need a pencil grinder (or a Dremel, if you don't have an air compressor), and a small teardrop 1/8"-shank carbide burr (something like THIS... 5th or 6th from the left). You'll also need a steady hand, because you'll be grinding that bit out. If you're careful enough in removing the broken bit, you should be able to drill the hole a little larger, and use the next-size-up extractor. I don't know if you used an form of Loc-tite on the bolts, but you may have to use a bit of heat as well.

Source: Aircraft mechanic for 10 years, and have removed many bolts/screws in this fashion.

Dremel has some attachments that would work (like these). If you don't have a dremel, you can run them in you drill.

Cut the crack down with a round file, sandpaper on a 1/4" dowel, dremel..burr might work best or a bench grinder. If it's the alum block and not the stick, just use the other side.

My girlfriend got me a set of cheap chinese tungsten carbide carving burs off of amazon. I find myself using them and a few of the sanding drums very often.

I can't find the exact set anymore, but they're very similar to these:
