I feel your pain Dave, I broke three Micro100 1/8” endmills this week myself. I did finish my part before I broke the third one though.

I had a lovely dormer carbide end mill which I got for a good price on ebay NOS.

I forgot to tighten a gib probably the second time i used it and the part grabbed taking out two flutes , it now lives in my box of shame along with a few taps and other end mills I have been bad to.

Well, I must say I'm shocked. I've never broken a drill bit or burned up an end mill or trashed a nearly completed part because I forgot to tighten the vise.

Nope, not me.

Very often...

First time I broke a Cobalt 31/64 drill bit drilling some darn hard aluminum. So much for China made drill bits.

I've smoked a few end mills on the Bridgeport when running a CNC routine. Lack of chip removal was the problem. Nothing like letting a routine run on its own while doing other work at the workbench, hear a funny noise, look over at a red-hot carbide end mill travelling around the part.

Of course, snapped off drill bits, broken taps from trying to get one more hole out of a dull one. Snapped off carbide inserts on the lathe while parting or turning.

Sorry wasn't in the shop today, but I did manage to wrap the bottom wire from the chain link fence around the lawn mower shaft.

Very succinct. Quite funny. More truth than poetry. I am struggling to come up with anything more comprehensive, accurate or timely. I will take my place amongst the "clumsy bastards" and call it a night.
