The Omega BT40 End Mill Holder is a precision tool holder designed for BT40 spindles, built to securely grip 14 mm end mills during high-speed milling. It helps maintain accurate tool positioning and stable cutting performance, making it suitable for shops that demand repeatable results across aluminum, steel, and other materials.

With a 63 mm gauge length and Form AD design, this holder delivers stable balance and reliable seating at speeds up to 20,000 RPM. It’s manufactured to a G2.5 precision standard, ensuring tight runout and consistent performance over many cycles.

• High-speed capability up to 20,000 RPM: Engineered for fast, stable cutting in BT40 spindles, minimizing vibration and maintaining tool position during aggressive feeds.
• Precise G2.5 runout tolerance: Delivers repeatable tool seating and accurate alignment for consistent finishes and reduced scrap.
• 14 mm bore, 63 mm gauge length (Form AD): Securely clamps 14 mm end mills and provides rigid, predictable reach for demanding milling applications.

In everyday use, this holder translates to fewer tool changes, greater cutting stability, and more consistent results across a range of materials. Its durable construction and precise dimensions help you achieve clean finishes, longer tool life, and reliable performance in high-speed CNC environments.
