The drill is screaming!
A customer brought in their bike because the hex socket on the fixing bolt of the FC-9100 left crank got stripped. They said it's okay to destroy it as long as I can recover the bolt.
At the point of the image above, I've already ground off the bolt head from the threaded section, and I'm using the Imoneji Recovery Tool (a specialized stuck bolt extractor) to loosen and remove it bit by bit.
Got it recovered.
Since I'm only blowing off the bolt head to release the clamping force, the drill bit never touched the aluminum of the crank at all.
The stuck-bolt-like part is no longer needed, but I'm keeping this head section to remember what size drill bit I used.
Specialized tools really are handy.
Even though this one hardly ever gets used otherwise.
