DESCRIPTION
Product Overview
The VBGW110304-2S CD6100 is a high-precision, 35-degree rhombic PCBN (Polycrystalline Cubic Boron Nitride) turning insert engineered for high-speed fine finishing and hard turning of Hardened Steel (HRC 45–65), High-Chromium Cast Iron, and Powder Metallurgy Metals. Featuring a 0.4mm nose radius and 2 fully indexable solid CBN cutting tips (-2S), this G-class ground insert delivers incredible hot hardness, superior thermal shock resistance, and extreme wear resistance. It allows CNC operators to replace costly, time-consuming cylindrical grinding operations with high-efficiency direct hard turning.
2. Technical Specifications

Grade: CD6100 (High-content PCBN composite substrate engineered for extreme thermal oxidation resistance and flank wear resistance in ISO H and K materials)
Shape: V-Shape (35 Degree Diamond / Rhombic)
Relief Angle: B-Type (5 Degree Positive clearance – lowers radial cutting forces during copy profiling)
Cutting Corner Configuration: 2-Corner Solid PCBN Tips (-2S)
Inscribed Circle: 6.35 mm (1/4 inch)
Thickness: 3.18 mm
Nose Radius: 0.4 mm (R0.4 / 1/64 inch) – Micro-sharp precision radius for mirror-like surface roughness and light depths of cut
Machining Type: Continuous to light interrupted hard turning, internal boring, profile turning, and facing
Applications
Workpiece Materials: Hardened Steel (HRC 45–65), Case Hardened Steel, Bearing Steel, Tool Steel, and High-Strength Cast Iron.
Industries: Automotive (gears, shafts, bearings), Aerospace, and Mold & Die manufacturing.
Cutting Conditions: Primarily used for Hard Part Turning (HPT) in continuous or slightly interrupted cutting applications.











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.
