Long story short I was running my DeWalt fixed base router (8000-24000 RPM) on a piece of work when it started making a funny noise.

I lifted the router up to see why it was making the noise, and FWOOOM the router bit launched itself into the air!

Router bit after launch

I found it on the lawn on the other side of the house, with the stalk all twisted to one side. It landed in soft grass so that damage must have occurred while it was in (or exiting from) the router.

No injuries occurred thankfully, but obviously someone easily could have been hurt. So, what happened? Was it just loose? Is my router card revoked and I should just go back to belt-sanding roundovers? What safety steps could I have missed? Thanks!

    Hello, and welcome to Stack Exchange. I'm no pro, but a loose bit could get off-center, and off-center at 24kRPM could do some serious damage to the bit, especially as it exited the router at speed. – Daniel Griscom Sep 12 '18 at 20:05
  • I agree it probably was not tight enough. I have never had one come out but have had them bend. – Ed Beal Sep 12 '18 at 20:32
  • Thanks! What about depth of insertion? – yourcomputergenius Sep 12 '18 at 20:33
  • It may have been both, not in far enough and not tight enough. The noise you heard was likely a bent bit before blast off. TBO, the router is my most feared power tool and I've never had a mishap with it. I give it and the tablesaw the upmost respect. – Gary Bak Sep 12 '18 at 21:27
  • This was scary! I usually use a small table-mounted router which seems a bit safer. Also, some bits are only rated for certain speeds... – yourcomputergenius Sep 12 '18 at 21:34
