BT40 Hydraulic Tool Holder | Guhring

Engineered to deliver exceptional component surface finish quality and maximum machining precision, the Guhring BT40 Hydraulic Tool Holder range represents the pinnacle of premium CNC tool holding. Manufactured to strict MAS 403 BT40 industrial standards, these premium hydraulic expansion chucks utilize a sophisticated internal fluid pressure system to exert a uniform 360-degree radial clamping force around the tool shank. This advanced mechanism achieves exceptional concentricity with a guaranteed runout tolerance of . Crucially, the internal oil chamber acts as a high-performance vibration dampening cushion, absorbing micro-chatter during high-feed finishing or demanding drilling cycles. This structural rigidity directly preserves the sharp cutting edges of solid carbide end mills, significantly extending tool life across premium manufacturing, aerospace, and high-tolerance precision engineering setups.
