How do I check whether my router or collet is out of true?
| Reading at the shank | Verdict | Next step |
|---|---|---|
| Under 0.03 mm | Good | Look elsewhere for chatter |
| 0.03-0.05 mm | Acceptable | Clean the collet and re-seat |
| 0.05-0.1 mm | Poor | New collet, check for resin or a burr |
| Over 0.1 mm | Bad | Bent shank or damaged spindle taper — stop using it |
How to isolate the cause: measure on the bare collet nut, then on a bit shank. If the nut is true and the bit is not, the bit is bent. If both are out, the spindle or the collet is worn.
What runout does to your work: one flute does all the cutting, the edge overheats, and you get a fuzzy edge plus a burning smell long before the bit looks dull.
