DESCRIPTION

Product Overview

The TCMT110208-GF CD7225 is a high-precision, single-sided 60° triangular positive turning insert engineered for high-efficiency fine finishing and semi-finishing of ISO P (Steels) and ISO M (Stainless Steels). As visible on the packaging label of TCMT110208-GF-5.jpg, this model combines a strong 0.8 mm nose radius with the ultra-low force -GF finishing chipbreaker and the remarkably versatile CD7225 PVD-coated matrix. It provides a light, vibration-free cutting action making it the ideal choice for internal boring bars, small CNC lathe lines, and slender components where part deflection must be strictly prevented.

2. Technical Specifications

• ISO Code: TCMT110208-GF

• Grade: CD7225 (Advanced multi-layer PVD coating optimized for exceptional edge toughness across ISO P20–P30 and M20–M30 finishing ranges)

• Shape: T-Shape (60° Triangle)

• Relief Angle: C-Type (7° Positive clearance – drastically minimizes radial forces and machine torque)

• Nose Radius: 0.8 mm (R0.8 / 1/32") – Delivers robust corner rigidity while achieving a fine, predictable surface roughness profile under finishing loads.

• Chipbreaker Design: -GF Finishing Geometry (Features a highly positive rake face with micro-wave deflector ridges near the point to break thin, ductile chips cleanly).

• Machining Type: Internal boring, precision external profiling, face-turning, and ultra-fine finishing.

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.
