They’re ideal for milling, drilling, reaming, and finishing operations across aerospace, medical, and automotive industries.

Key Features and Important Usage Guidelines of BT40 Hydraulic Chucks

• Hydraulic Clamping System Delivers consistent pressure with minimal torque, ensuring precise tool positioning and superior surface finishes.
• High Speed & Ultra-Low Runout Factory-balanced to G2.5 at 25,000 RPM with runout under 0.002 mm—ideal for high-speed, high-accuracy applications.
• Shank Tolerance h6 Required Only compatible with tools manufactured to an h6 tolerance for optimal hydraulic grip.
• Safe Clamping Guidelines
  • Do not use tools with weld-on flats (Weldon-type tools).
  • Never clamp the chuck without a tool inserted.
  • Cutting tools must be inserted beyond the minimum clamping depth of 36 mm.
  • Do not exceed the maximum clamping depth of 46 mm.

These guidelines help preserve the hydraulic chuck’s internal sealing system and deliver repeatable precision.
