CNC Milling Cutter Type V 20° 0.4mm - DNG-18360

The CNC V-type milling cutter Type V 20° 0.4mm (model DNG-18360) is a precision routing tool designed for CNC machining tasks that require a narrow V-profile and accurate edge geometry. With a 20° included angle and a 0.4 mm tip, this cutter is intended for fine detail work such as V-grooves, chamfers and engraving. It is compatible with common CNC setups and suitable for use in woodworking, plastics and softer metals where a small, sharp V-profile is needed.

Advantages

This V-type milling cutter provides consistent cut geometry due to its 20° angle and fine 0.4 mm tip, enabling precise V-grooves and sharp chamfers. Its geometry minimizes material tear-out on wood and plastics and supports fine-detail engraving with repeatable results. The cutter’s small tip diameter allows for high-resolution profiles and clean edge definition when used at appropriate feed rates and spindle speeds.

Suitable for

• V-grooving and decorative routing on wooden panels
• Fine engraving and lettering in plastics
• Small chamfers and edge detailing on soft metals
• Prototype detailing and sign making

Key specifications

• Tip diameter: 0.4 mm (fine V point)
• Included angle: 20° for narrow V-profiles
• Tool type: V-shaped milling cutter for CNC routing
• Typical materials: wood, engineering plastics, soft non-ferrous metals
• Application: V-grooves, chamfers, engraving and fine-detail cutting

How to use

Install the cutter securely in a compatible collet or tool holder and verify concentricity before machining. Select spindle speed and feed rate appropriate to the work material and cutter diameter; higher spindle speeds with moderate feeds typically reduce chipping in wood and plastics, while lower speeds may be necessary for certain soft metals. Perform test cuts on scrap material to confirm depth of cut and feed. For precise V-grooves, program the toolpaths to follow the intended profile and use multiple shallow passes rather than a single deep pass when higher material removal is required.

Usage recommendations

Use appropriate dust extraction and workpiece clamping; wear eye and hearing protection when operating CNC equipment. Regularly inspect the cutter for wear or damage and replace when the tip becomes dull to maintain clean edges and accurate profiles. For extended tool life, avoid excessive depth of cut and maintain recommended spindle speeds and feed rates for the chosen material.
