The Omega BT40 Shrink Fit Chuck is a high-precision tool-holding solution designed for BT40 spindles in high-speed CNC milling and drilling. It uses a shrink-fit design that expands with heat to grip the tool shank securely, delivering consistent concentricity and reliable performance in demanding work. With a G2.5 precision rating, you’ll experience excellent tool concentricity and minimal runout for accurate, repeatable results.

With a maximum speed of 25,000 RPM, a 10 mm tool shank, and a 120 mm overall length, this chuck offers a balanced blend of reach and rigidity. It stays stable at high speeds, helping you achieve smoother cuts, better surface finishes, and reduced deflection across a wide range of milling and drilling tasks.

• G2.5 Precision Concentricity: Delivers tight runout and stable tool alignment for every pass, producing consistent hole diameters and surface finishes.
• High-Speed Performance up to 25,000 RPM: Maintains precision at top speeds, enabling efficient milling with reduced chatter and smoother finishes.
• Heat-Expanded Shrink-Fit Clamping: The shrink-fit mechanism provides an even, secure grip on the tool shank for superior stability and vibration damping.

This BT40 Shrink Fit Chuck is designed to deliver repeatable, reliable results in busy workshop environments. Its precise grip, stiff construction, and high-speed capability help you maintain tight tolerances, improve surface quality, and extend tool life across demanding machining cycles.
