The Omega BT40 End Mill Holder is a precision toolholding solution designed for BT40 spindle systems used in CNC milling and high-speed machining. It securely clamps end mills to minimize runout, delivering repeatable tool positioning and consistent cut quality in demanding milling operations.

Key specs at a glance include a 25 mm bore, 160 mm gauge length, Form AD/B, a precision class of G2.5, and a maximum speed rating of 20,000 RPM. Crafted from high-quality materials, this holder delivers rigid performance and long-lasting stability under heavy workloads.

• Secure, precise tool retention: firm clamping reduces runout and chatter, ensuring repeatable tool seating and accurate, consistent cuts.
• High-speed milling ready: engineered to perform reliably up to 20,000 RPM with maintained concentricity, helping achieve cleaner finishes and longer tool life.
• Rigid, durable construction: Form AD/B compatibility with BT40 spindles, 25 mm bore, and 160 mm gauge length, built from durable materials for long-term stability and wear resistance.

This holder helps your workflow stay efficient by delivering stable tool seating, reducing downtime from misalignment, and producing consistent results across batches. With its rugged construction and precise tolerances, you can rely on steady performance in busy shops and demanding production environments, ensuring you meet tight tolerances and maintain high throughput day after day.
