The Sandhog MCKNR2525M12 is a high-performance external turning tool holder designed for precision machining applications on CNC lathes and turning centers. This 75° cutting angle tool holder is engineered with robust materials and advanced manufacturing techniques to deliver exceptional stability, durability, and versatility in industrial machining operations.
Key Features
Superior Rigidity and Vibration Damping
Constructed from high-grade alloy steel and heat-treated for enhanced hardness, the MCKNR2525M12 minimizes tool deflection and vibration during heavy-duty cutting. The optimized geometry and reinforced clamping mechanism provide excellent resistance to chatter, ensuring improved surface finish and dimensional accuracy even in high-speed operations.
Compound Composite Clamp M-Type Design
The advanced clamp design securely holds the insert, minimizing tool wear and ensuring consistent cutting performance. This design allows for quick and secure insert changes, reducing downtime and increasing productivity.
Wide Insert Compatibility
The tool holder is compatible with standardized CNMG-style inserts (12 mm cutting edge), including CNXX1204, CNXX1606, and CNXX1906. This modularity makes it suitable for a wide range of materials, including steel, stainless steel, and cast iron.
Thermal and Wear Resistance
A specialized surface coating reduces friction and heat buildup, extending tool life in high-temperature machining environments. The negative rake angle design enhances chip control and tool life, making it ideal for demanding applications.
Precision Engineering
Processed with high-precision CNC machining centers, the tool holder offers excellent dimensional accuracy and smooth cutting performance. Precision-ground surfaces and clear identification markings simplify setup and alignment, reducing operator error.
