Collet Spacer Sleeve/Shaft Extender, Straight Shank

[High-Speed Steel Shaft] The heat-treated high-speed steel shaft resists deflection and bending, reducing the need for extra-long tools in deep cavity operations.
[Internal Cooling] The central through hole allows for water-based cooling directly at the cutting interface, decreasing heat buildup and extending tool life.
[Vacuum Hardened Core] The advanced vacuum hardening furnace impregnates carbon and oxygen into the steel, increasing shaft hardness for heavy-duty applications on CNC lathes and milling machines.
[Cost-Effective Configuration] Eliminates the need for expensive extended tools, allowing standard toolholders to achieve extended reach in milling and drilling operations.
[Fixed Straight Shank] The C12-DC06-200L back-draft collet fixed securely in lathe chucks, minimizing vibration and runout for precision turning applications.
