Omega's BT40 Shrink Fit Chuck provides secure, precise tool holding for BT40 spindle machines and high-speed milling. With a G2.5 precision rating for exceptional concentricity and minimal runout up to 25,000 RPM, it accepts 25 mm tool shanks within a compact 120 mm length, delivering stable performance on demanding work. The heat-expanded shrink-fit design grips the tool shank firmly, delivering vibration damping and consistently smooth finishes.

• Ultra-precise concentricity: G2.5-rated accuracy delivers minimal runout, helping you hit tight tolerances and achieve consistent part finishes.
• Secure high-speed retention: Robust tool grip supports speeds up to 25,000 RPM, keeping the 25 mm shank centered under load for stable milling and reduced deflection.
• Heat-expanded vibration damping: The shrink-fit mechanism expands with heat to firmly hold the tool, providing excellent vibration damping for smoother cuts and longer tool life.

With the BT40 Shrink Fit Chuck, you gain reliable, repeatable toolholding that reduces setup time, minimizes runout, and delivers consistent finishes even at high speeds. Its compact 120 mm length and 25 mm shank compatibility fit neatly into BT40 spindles, while the G2.5 precision and heat-assisted grip provide lasting stability and vibration damping. This means fewer reworks, higher productivity, and improved overall machining results across a range of materials and applications.
