My brand new, $400 track saw blade decided to explode into a dozen pieces while I was cutting some maple plywood for a built-in last Thursday.

I was halfway through a 4x8 sheet when it sounded like a gunshot and I spent the next hour picking carbide teeth out of my shop wall, so has anyone else had a blade just completely disintegrate like that?

Honestly, that sounds like a setup or material issue, not the blade. A brand new blade doesn't just blow up on clean maple ply unless it was pinched or there was a nail in there. I've cut miles of sheet goods and never seen that happen without a clear cause.

Yeah, @wesleyb20 is totally right. Honestly, a blade just giving out like that almost always means something was wrong with the cut itself or the wood had a hidden flaw. Seen it happen before when the board had some weird internal stress.

Totally agree with both of you. Watched a guy at the shop have a blade explode on some oak that looked perfect. We were all baffled until we found the spot where a tiny branch had grown straight into the trunk years before. It created this hidden knot and crazy tension. The wood just grabbed the blade and that was it. Makes you check every board twice now.
