SGBR2020K16 External Turning & Threading Tool Holder: Versatility Meets Performance

Double the Duty, Single Holder. The SGBR2020K16 is the ultimate versatile workhorse, engineered for both precision external turning and robust threading operations. Its ultra-rigid 20x20mm block and versatile K16 interface deliver unmatched stability for flawless finishes and perfect threads, maximizing your tooling flexibility.

Key Features & Benefits:

• Dual-Function Design: One holder handles both external turning and threading operations, reducing tooling inventory and changeover time.

• Supreme Rigidity: The massive SGBR 20x20mm block construction guarantees exceptional stability, minimizes deflection, and eliminates chatter for superior surface finishes and thread accuracy.

• Secure K-Type Clamping: The top-clamp (K16) mechanism provides superior insert locking force and reliability for both turning and threading inserts, ensuring safety and consistency.

• Right-Hand Configuration: Ideal for standard external machining operations on most CNC lathes.

• Enhanced Productivity: Simplifies tool management and increases machine uptime by combining two essential functions into a single, robust platform.

• Industry-Standard Compatibility: Uses readily available K16-style turning and threading inserts, offering flexibility and cost-effectiveness.

Ideal for: Job shops, general machining, and maintenance facilities that value versatility, precision, and efficiency in external turning and threading applications on CNC lathes.

CNC Inserts - Frequently Asked Questions

1. How do I choose the right grade for my specific machining application?

Choosing the correct grade is crucial for tool life and performance. We provide a comprehensive Grade Cross-Reference Chart that maps our CD Carbide grades to major international brands like Sandvik, Mitsubishi, and Kyocera. If you are unsure, simply provide us with the workpiece material (P, M, K, S, H) and machining conditions, and our engineers will recommend the best solution.

2. Can you provide customized CNC tools based on our drawings?

Yes. As a factory-direct manufacturer, we specialize in bespoke engineering. Whether you need non-standard dimensions, specific chipbreakers, or customized coatings for unique alloys, our technical team can develop products based on your technical drawings (PDF/STEP) or physical samples.

3. Do you offer free samples for testing before bulk orders?

We understand that "trial cutting" is the only way to verify tool stability. We offer sample packs for professional buyers to test performance on their own CNC machines. Please contact our sales team with your machine specifications and the material you are processing to request your trial samples.

4. How do you ensure the quality consistency of your carbide inserts?

Our quality control is integrated into every step of the production process in Zhuzhou. We use high-purity tungsten carbide powder and advanced PVD/CVD coating equipment. Each batch undergoes rigorous inspection, including microscopic edge analysis and hardness testing, to ensure that the performance of the 1,000th insert is identical to the 1st.

5. What is the typical lead time for international B2B orders?

For standard models in stock (such as WNMG, CNMG, etc.), we usually ship within 3-5 business days. For customized tools or large-volume OEM orders, the production cycle typically ranges from 2 to 4 weeks, depending on the complexity of the design and coating requirements.

6. Are you a manufacturer or a trading company?

We are a direct manufacturing enterprise based in Zhuzhou, the hunan of China’s tungsten carbide industry. By cutting out the middleman, we provide factory-direct pricing and faster technical support. This allows us to offer more flexible MOQs (Minimum Order Quantities) for small-to-medium-sized distributors and specialized machine shops.
