I was wondering if someone has created or if the Inventables people have done this. A color-coded poster of all the different bits and the colors of the bands. This is a little thing, and I know the size of the bit is printed extremely small on the ring, but I have to use a magnifying glass to read the print (darn old man eyes!).
It would be much easier if there was a downloadable chart with this information that I could print out and post near my X-Carve.
What I did was to keep the bits in the plastic container they came in, and write on the outside (with a Sharpie) the size, and type of cut, and also the colour of the ring eg: “1/8 spiral upcut, white”. Makes it much easier to pick the right bit.
I didn’t make this, but I don’t remember who did to give adequate credit. Hopefully it will prove helpful. And whoever knows the origin, feel free to chime in!
However… that chart only applies to Inventables bits.
I get most of my bits on Ebay (drillman) and can tell you that the colored rings are not always an indication of what bit you are using. I do not think there is any “standard” to the colored rings.
