DESCRIPTION

SGBL2020K16 External Grooving Holder: Precision and Power for OD Grooving

Engineered for high-performance CNC lathes and turning centers, the SGBL2020K16 is the ideal choice for manufacturers who demand repeatability, superior surface finish in grooves, and maximum tool life in demanding production or job-shop environments.

Key Features & Benefits:

• Ultra-Rigid Block Design: The massive 20x20mm SGBL body provides supreme stability, enabling deeper cuts, higher feed rates, and superior performance in tough materials.

• Superior K-Type Clamping: The top-clamp (K16) mechanism ensures incredibly secure insert locking for maximum safety and reliability, preventing insert movement during intense cutting operations.

• Excellent Chip Control: Designed to work with dedicated grooving inserts that feature advanced chipbreaker geometries, promoting efficient chip evacuation and preventing chip jamming.

• Right-Hand Configuration: Optimized for standard external grooving and parting on modern CNC lathes.

• Boosts Productivity & Reduces Cost: Minimizes vibration-related insert failure, provides consistent performance, and allows for aggressive machining parameters to reduce cycle times.

• Industry-Standard Compatibility: Uses readily available K16-style inserts, offering flexibility and reducing inventory costs.

Ideal for: High-volume manufacturing, job shops, and any application requiring precise, reliable, and efficient external grooving, parting, and profiling 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.
