Was surface planing with a 1-1/4 surface planing router bit from Magnate. I've had this bit for at least 12 years, it was a great bit. That is until it threw a chunk of carbide off at 18,000 rpm. I didn't hear anything, but the router started shaking a little bit.

Just a gentle reminder to give your bits a good looking over before you use them. I hadn't seen anything wrong with this one before I started, and the walnut I was turning didn't have any metal in it, so I guess it just finally had enough.

Glad you missed the shrapnel. Plus 1 on inspecting the bits prior to using them.

When I chucked up my new HF slot cutters the other month lets just say I would have put on a face shield if I had had one.

Its typical for a fractured bit

Not something that you'll want happening but sometimes really hard to tell before hand. Glad it wasn't anything more than a bad bit and no bloodshed to deal with.

The break looks all fresh so I have my doubts you would see any problem with it ahead of time.
