X-Head Porting....

I only have one burr that’s solid carbide.
It’s a 1/4” short tree shape.

Every other one I’ve ever bought was a carbide attached to what appears to be a stainless shaft.

If they’re bending just by hitting the switch...... perhaps there is some runout in the collet.

Possibly there is some runout in the collet from when the larger bur got stuck and broke a bit. Its weird though because I ran 2 other bits in the drill and those spin just fine.

Let's just chalk it up to my luck. I'll see how my cheap 1/8 shank burs do tomorrow.
