Upgrade your tooling performance with our ER Arbor, engineered for superior accuracy, rigidity, and balance in high-speed CNC machining centers. Designed to hold ER collets securely and reliably, this arbor ensures stable cutting, reduced vibration, and extended tool life across a wide range of milling, drilling, and tapping applications.

Key Features

• High-Precision Taper (BT30/ BT40/ BT50)
  Manufactured to strict tolerance standards for optimal spindle fit, improved rigidity, and consistent machining accuracy.

• ER Collet System Compatibility
  Works with ER collets (ER16 / ER20 / ER25 / ER32 depending on model) for maximum versatility in tool holding—ideal for end mills, drills, taps, reamers, and more.

• Superior Tool Balance
  Precision-ground for excellent balance at high RPMs, minimizing vibration and improving surface finish.

• Durable Alloy Steel Construction
  Heat-treated, hardened, and precision ground to resist wear and maintain accuracy over long-term industrial use.

• High Clamping Force
  Provides exceptional holding strength, reducing tool slippage and ensuring predictable machining performance.

• Corrosion-Resistant Finish
  Protects against coolant exposure and wear in high-production environments.
