So first 2 caveats:
1) I just can't keep up with the thread (or the forum) so apologies if this has been previously posted
2) as much as I don't want to promote Dumb & Dumber at TIA the overall content is what's relevant here
Video about the Milwaukee "Matrix Carbide" bits exploding:
I've never been impressed with any of Milwaukee's impact driver expendable offerings, but as a machinist I'm not all shocked to hear that carbide is exploding. We all know it's brittle and doesn't like "interrupted cuts" as we say
Now granted I have no idea what GRADE or COMPOSITE of carbide they're using here, but I can tell you exactly what happened:
Chinese quality fade.
Carbide can be fine tuned for hardness or toughness, but somebody somewhere decided that carbide is carbide, and/or spilled his Coke in the mixture, and they ran off a massive amount of inferior product.
OMG I solved the case in 3 seconds flat
Oh and I did only watch the video skipping ahead about a minute each and then watching 10 seconds before skipping another minute, and on and on
9 1/2 minutes of unprofessional, slovenly guys clearly looking like they don't care and don't want to be there standing behind a bench just running their mouths about the same topic....for 9 1/2 minutes. Oi vey
