So I finally hit a screw with my brand new bosch power planer.
Now I fully expected to do this. What I didn't expect was for it to shatter one of the blades.



Here's a quote from the manufacturer:Really??
Can I get a WTF?

Sad to say but hardness and brittleness pretty much go hand in hand.

I understand your pain... I ruined a 1 1/2" carbide forstner bit drilling "The Hole" in Gentry. I ended up grinding the carbon steel backing plate to an edge just to get finished.

I think the problem is that the planer is not solidly mounted so it bounces and the shock load cracks the brittle tungsten carbide. On a lathe if you have any slack in the saddle it will do the same thing, but if you get rid of the slack and bite deep it just roars on through. At least they are easily replaceable blades.

Understood. It's just the whole "resist fractures" BS that pisses me off.
I plan on buying the high speed steel blades for a replacement.

That's one reason I use belt sander....it just takes out the screw

I bought a set of carbide blades for my Makita and they shattered on the white oak. I didn't even hit a screw. Sanding does work better.
