BMT Toolholders for Turning Centers
BMT (Bolt-Mount Turret) toolholders are precision-engineered toolholding systems designed for direct mounting onto BMT-style turret interfaces on CNC turning centers. Offering exceptional rigidity, accurate positioning, and reliable repeatability, they are the preferred choice for high-performance turning and mill-turn operations.
Product Overview
BMT toolholders mount directly onto the face of the turret, providing a flat, rigid seating surface that significantly reduces tool overhang and deflection. This design translates directly into improved surface finish quality, tighter dimensional tolerances, and extended cutting tool life.
Available in both straight and angular configurations, these toolholders support a broad range of machining operations — including axial drilling, radial milling, tapping, and off-center operations — on a single setup.
Key Features
- Bolt-mount turret interface for maximum rigidity and minimal vibration during cutting.
- Straight and angular tool-head configurations to support diverse machining requirements.
- Internal coolant delivery options — standard and high-pressure up to 80 bar — for effective chip evacuation and tool cooling.
- Precision-ground seating surfaces ensure accurate and repeatable tool positioning across changeovers.
- Manufactured by Live Tools Division to stringent quality and dimensional standards.
