The Omega BT40 Slim Shrink Fit Chuck is engineered for high-precision machining in space‑constrained setups. Its compact, slim profile delivers strong tool retention and smooth operation at high speeds, making it ideal for close‑clearance milling, drilling, and finishing tasks. Manufactured to BT MAS403 (JIS 6339) standards, it delivers reliable clamping strength and rigidity, with a 3‑degree taper and Form AD/B for balanced performance up to 25,000 RPM. It features a 6 mm clamping diameter and a 90 mm gauge length to provide a compact yet versatile gripping solution.

  • Rigid, secure shrink‑fit clamping: BT MAS403/JIS 6339‑compliant construction ensures strong grip and repeatable retention with minimal runout, so tools stay perfectly aligned during high‑speed milling.
  • Balanced high‑speed performance: 3‑degree taper with Form AD/B delivers stable, vibration‑controlled operation at up to 25,000 RPM for clean finishes and longer tool life.
  • Slim BT40 design for tight spaces: The compact profile, 6 mm clamping diameter, and 90 mm gauge length maximize accessibility in crowded setups without sacrificing rigidity or grip.

This combination of precision clamp, speed‑ready balance, and space‑saving form makes the Omega BT40 Slim Shrink Fit Chuck a reliable core component for any high‑speed machining cell. Expect repeatable tool retention, reduced runout, and smoother finishes across milling and drilling tasks, even in tight work envelopes. With fast tool changes and proven BT MAS403/JIS 6339 compliance, you can trust consistent performance over long production runs, minimize downtime, and improve overall throughput.
