Engineered for precision and durability, this 300mm square cutter CNC lathe turning tool bar is crafted from high-speed steel (HSS) for superior wear resistance and edge retention. Available in six essential sizes from 6x300mm to 18x300mm, it delivers reliable, high-speed cutting performance for demanding turning operations. Features and Benefits
- High-Speed Steel (HSS) Construction - Provides excellent hardness and heat resistance, maintaining a sharp cutting edge longer than standard carbon steel for consistent, high-quality finishes.
- 300mm Overall Length - Offers ample reach and leverage for a wide range of lathe setups and workpiece sizes, enhancing versatility in the workshop.
- Square Cutter Bar Design - Ensures maximum rigidity and stability during heavy cuts, minimizing tool deflection and vibration for improved accuracy.
- Multiple Size Options (6mm to 18mm) - Allows machinists to select the exact shank diameter for their specific application, ensuring optimal tool holding and cutting force.
- White Steel Finish - Indicates a precise, uncoated HSS grade that is easy to re-sharpen and maintain, extending the tool's service life with proper care. Applications
- General Purpose Turning on CNC Lathes - Ideal for facing, shoulder turning, and straight turning operations on a variety of materials including mild steel, aluminum, and plastics.
- Toolroom and Maintenance Machining - A reliable, value-focused choice for repair shops, prototyping, and one-off jobs where consistent performance is required.
- Educational and Training Workshops - An excellent, budget-friendly tool for vocational schools and training centers to teach fundamental lathe operations without compromising on functionality.
