dremel bit - name your tool...

[Keith Black]

This is a great thread. I really like hearing what people use for different purposes. Unfortunately I'm not sure what some of you are referring to because there are so many different tips and cut-off tools.

Below is a link to all dremel rotary tips. Now we can share what each person uses with a positive ID based on the tool number.

I'll start. When cutting long straight lines in fiberglass or carbon fiber I use cutting tools 456 or 540. I like 456 because it's bigger and easier to reach flat areas, but for shorter straight lines I'll use 540. For going around corners I use 562, this is actually called a "Tile Cutting Bit" but I find that it does a good job on carbon/fiberglass and is less likely take-off uncontrollably than the other cutting bits such as 560 and 561. After cutting with 562 I will then sand smooth with a sanding drum tip 444 or 438.

  I prefer to use Dremel grinding stones on composites. They're easy to control and won't snag Kevlar as a burr or drill can. The conical styles allow cutting lines with the tip, making smooth radii with the larger end, and boring holes from small to large. Cutoff wheels work well on straight cuts. 

  (Be careful if using the round saws, a friend lost control of one and it ran up his thumb / arm as deep as the shaft would allow, finally to be stopped at his watch band.)

    For the stright line areas, a thin minature round saw blade works very well.
    It may take a bit of practice to keep the blade aligned in the cut to avoid binding.
    For curved areas, I find the smallest diamond patterned cutter works well.  I use it to get close to the desired cut, then a sanding drum to finish cutting to the final edge.
