Heavy Duty ER Extension Rod For SL25 And ER25 Tool Holders Side Fixed Design Ensures Ultra Low Runout With Precision Ground Steel For Stable CNC Milling And Lathe Operations At High Speeds Without Vibration

ER Rod Keeps Tools Stable For High Speed CNC Milling Work
✔️ 40CrMnTi Alloy Steel HRC56 Hardness 0.008mm Accuracy Fits ER Collet

This solid steel extension tool connects directly to your ER collet system on mills or lathes. You can reach deep pockets or narrow slots without sacrificing cutting rigidity when machining tough metals.

✅ Precision ground body maintains 0.008mm tolerance for accurate cuts every time
✅ Heat treated 40CrMnTi steel offers strong core resistance against bending loads
✅ Threaded nut locking mechanism prevents any loosening when running heavy speeds

💡 How Does Extension Rod Quality Affect CNC Milling Performance And Surface Finish? Better stability leads to cleaner surfaces on complex projects.
- Rigid material properties minimize flex during aggressive cutting actions today.
- Low vibration ensures tighter tolerances on delicate component shapes produced.
- Secure mounting reduces chatter marks left on difficult workpiece surfaces
