My router bit chipped on a maple panel last month and I had to think fast

I was running a cove cut on a big piece of hard maple for a built in, something I've done a hundred times. Halfway through the pass, I heard a nasty ping and saw a shiny piece of carbide fly off. The bit was a 3/4 inch Whiteside I'd had for years. I had to stop the job right then. I checked the cut and there was a bad tear out about six inches long. I ended up using a sharp chisel to clean up the tear out by hand, then switched to a smaller bit to finish the profile in two lighter passes. It cost me most of an afternoon. I always thought those bits were bulletproof, but I guess everything wears out. Has anyone else had a good bit fail suddenly like that?

That's the router bit version of a veteran player tearing their ACL mid-game. Guess even the "bulletproof" ones decide to retire without giving two weeks notice. At least it didn't explode and take the whole project with it. Maple's no joke, it'll find the weak spot in any tool eventually.

Honestly, I've had the opposite luck. My cheap router bits always give up first, while the good ones just get dull. I've run a Freud bit through miles of oak and it just needed a sharpening. Maple is tough, but in my experience, a quality bit doesn't just snap. It's more like it slowly loses its edge and tells you it's time for a break.

Agree with @kai_ramirez38 about good bits usually just getting dull. That sudden chip sounds like a hidden flaw or maybe a tiny crack from an old hit. Maple really is the ultimate stress test for any tool.
