ER11A 5mm Steel Collet Spacer Sleeve Extender Single Unit Piece
✔️ Precision ground straight shank gives steady spin with no wobble

This metal spacer sleeve acts as a shaft extender for your spindle setup, letting you reach deeper into workpieces without chasing accuracy. Machinists typically drop these into their rig during boring, tapping, and tight spot milling when standard holders hit the dead center limit.

✅ Heavy duty steel body takes serious abuse during heavy cutting loads
✅ Balanced geometry cuts down vibration for cleaner pass runs
✅ Extra length allows safe tool extension beyond normal reach limits
✅ Comes sealed in labeled storage boxes ready for immediate install
✅ Handles drilling, grinding, and milling tasks without flex or play

💡 Why is a stiff steel spacer sleeve so handy when fixing dead center alignment issues?
Fixing that gap stops the wobble right away and gets your drill bit tracking true again. Here is exactly what you gain when you swap it out today:
- Tight shank fit locks the tool steady and kills chatter before it starts
- Balanced weight distribution keeps the spindle calm during rough cutting runs
- Hardened steel rings guard the surface so the chuck grips forever
- Fast swap saves bench time and lets you push harder on aggressive feeds
