DESCRIPTION

S20R-MTQNR16 / S20R-MTQNL16 CNC Turning Tool Holders

Product Description

The S20R-MTQNR16/S20R-MTQNL16 are professional-grade CNC turning tool holders designed for demanding machining applications. Compatible with MT/MTW16 series inserts (e.g., MTWN1604, MTGN1604), these holders feature:

• 16mm reinforced shank for maximum stability in roughing and finishing

• T-type quick-change mechanism for efficient insert replacement

• Right/Left-hand versions to accommodate all machining setups

• Precision-ground base for consistent cutting performance

Ideal for machining steel, stainless steel, cast iron, and heat-resistant alloys in automotive, aerospace, and general engineering applications.

Key Features

1. 16mm High-Rigidity Shank - Made of premium alloy steel with heat treatment for superior vibration resistance in heavy-duty turning operations

2. Dual Cutting Direction Options

• R-Type (Right-hand): S20R-MTQNR16 for conventional turning

• L-Type (Left-hand): S20R-MTQNL16 for special machining requirements

3. Quick-Change T-Type Clamping - Securely holds MT/MTW series inserts (16mm IC) with fast and precise insert changes

4. Optimized Chip Control - Engineered geometry for excellent chip evacuation in continuous and interrupted cuts

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.
