Unlock unparalleled accuracy in your small-diameter internal machining with our MGR series boring bars. Expertly engineered for precision grooving, profiling, and turning, these tools are essential for any machine shop producing complex parts with internal features. Whether you're creating grooves for circlips, O-rings, or performing intricate profiling, the MGR system provides the stability and precision needed for a perfect result, every time.
Specialized for Internal Grooving: The primary choice for machining precise internal grooves with sharp, clean corners and excellent surface finish.
Exceptional Rigidity: Available with [e.g., Solid Carbide or Heavy Metal] shanks to minimize vibration and prevent deflection in small and deep bores, ensuring dimensional accuracy.
Versatile MGR Insert System: Designed for MGR-style inserts, allowing for a wide variety of operations including grooving, profiling, turning, and face grooving with a single tool holder.
High-Precision Performance: The ideal solution for holding the tight tolerances required in the medical, aerospace, and hydraulics industries.
Through-Coolant Design (Optional): Select models feature internal coolant channels to effectively flush chips and cool the cutting edge, dramatically improving tool life and performance.
Multi-functional: Capable of performing a range of tasks beyond grooving, including boring, copying, and chamfering inside a part.
