DESCRIPTION

Product Detail：

This HRC55 2-flute carbide ball nose end mill is specifically designed for extreme reach and high-precision deep machining. With an impressive total length of 150mm, this tool is essential for deep-cavity and deep-pocket milling on high-hardness materials where no standard tool can reach.

• Extreme Reach for Deepest Cavities: The 150mm extra-long shank is engineered to provide maximum reach into the deepest pockets and tightest spaces. This eliminates the need for unstable tool extensions, ensuring unparalleled stability, rigidity, and reduced vibration during deep cuts.

• Precision Ball Nose Design: The D6mm ball nose tip is perfect for complex 3D curved surface machining, arc slotting, and fine contouring. It guarantees a smooth, precise finish, even at the maximum reach.

• 2-Flute Structure for Smooth Chip Evacuation: The optimized 2-flute design ensures maximum chip evacuation space, preventing chip clogging and secondary cutting. This is critical for maintaining high efficiency and a superior surface finish during deep vertical milling operations.

• Designed for High-Hardness Materials: Made from premium carbide, this tool is tailored for materials with a hardness up to HRC55. It features excellent thermal stability and wear resistance, making it the most reliable choice for machining hardened steel and mold steel at length.

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.
