DESCRIPTION

MGEHR2020-2-L35 CNC Lathe Indexable External Grooving & Parting-Off Tool Holder

Optimize your external grooving, parting-off, and turning operations with our professional-grade MGEHR2020-2-L35 External Grooving Tool Holder. Specifically engineered for CNC lathes, automatic lathes, and turning centers, this tool holder features a standard 20mm x 20mm square shank to deliver exceptional stability and rigidity.

Constructed from high-tensile hardened alloy steel, it effectively suppresses chatter and vibration under heavy loads, ensuring a premium surface finish and clean cuts during high-speed parting and profiling.

Key Features

• High-Efficiency External Grooving: Designed for precise external grooving, shallow slotting, and parting-off operations on various metal workpieces.

• Perfect Match for MGMN200: Fully compatible with industry-standard MGMN200-G (2.0mm cutting width) double-ended carbide inserts.

• Heavy-Duty Anti-Vibration Structure: Crafted from premium heat-treated alloy steel, reducing tool deflection and drastically extending insert tool life.

• Rigid Screw Clamping: Features a robust M6x14 clamping screw and a matching L5 hex wrench setup for reliable locking and quick, easy insert indexing.

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.
