CNC Milling Cutter V 20° 0.3 mm tip - DNG-17927 (frez typu V)

CNC V-type milling cutter with a 20° angle and a 0.3 mm tip radius, model DNG-17927, is designed for precision V-grooving, engraving and chamfering on a variety of materials in CNC routers and milling machines. The V 20° geometry and fine 0.3 mm tip enable narrow, accurate V-profiles and sharp detail cuts suitable for signmaking, decorative profiling and PCB edge chamfers. The tool is engineered for controlled material removal where a consistent narrow groove or crisp V-shaped contour is required.

Advantages

The 20° V-angle combined with a 0.3 mm tip provides high-precision engraving and consistent groove geometry. Its slim tip allows fine-detail work and narrow chamfers with minimal material displacement. The cutter’s geometry reduces cutting forces for smoother feeds and better surface finish on softer woods, plastics and non-ferrous metals when appropriate feed and speed are used.

Suitable for

• V-grooving and decorative profiling on wood, MDF and composites
• Fine detail engraving and signmaking
• Chamfering PCB edges and small mechanical parts
• Creating narrow V-profiles in plastics and non-ferrous materials

Key specifications

• Tip radius: 0.3 mm
• V-angle: 20°
• Intended use: CNC routing and milling for V-grooving, engraving and chamfering
• Suitable materials: wood, MDF, plastics, composites, non-ferrous metals (subject to appropriate speeds and feeds)
• Profile capability: narrow V-profile and fine detail cuts

How to use

Install the V-type milling cutter securely in the collet or tool holder of the CNC router or milling machine, ensuring correct runout and clamping. Select cutting parameters (spindle speed, feed rate and depth of cut) suitable for the material: higher spindle speeds with shallow passes for plastics and non-ferrous metals, moderate speeds for woods and composites. Make light finishing passes when producing very fine details or sharp V-edges to minimize tool deflection and achieve consistent groove geometry. Monitor tool wear and replace the cutter when tip rounding affects profile accuracy.

Usage recommendations

Use appropriate chip evacuation and dust extraction when machining wood and composites. For best results on PCBs and metals, apply coolant or air blast and reduce depth per pass to avoid excess heat buildup. Verify feed and speed on a test piece to balance surface finish and tool life before proceeding to final parts.
