I. Specifications of Double-Edge Milling Tools
Double-edge milling tools are like the Swiss Army knives of the engraving industry. Their specifications are usually expressed as diameter × blade length. Common specifications range from 1mm mini models to 20mm industrial models. Among them, the 4x6 model (diameter 4mm / blade length 6mm) is a versatile choice:
- Fine work: 1-3mm specifications are suitable for circuit board engraving
- Regular processing: 4-8mm can meet most wood and metal processing needs
- Heavy-duty cutting: Above 10mm is used for large material removal.
II. The Golden Balance of 4x6 Model
Why is the 4x6 specification so popular? It can be analyzed from three aspects:
- Cutting efficiency: The 6mm blade length ensures sufficient chip removal space
- Strength guarantee: The 4mm diameter provides excellent resistance to bending
- Versatile application: Compatible with various materials such as plastic, aluminum, and mild steel.
III. Buying Guide for Avoiding Pitfalls
When choosing, pay attention to these details to avoid unnecessary detours:
- Coating selection: No coating is suitable for aluminum materials, while titanium coating has a wider applicability
- Screw angle: 30° is suitable for precision processing, while 45° focuses on rapid cutting
- Handle diameter matching: Commonly available in three caliper specifications: 4mm/6mm/8mm.
