CNC Router Bit V‑Type 20° 0.5 mm - DNG-17928 by Unknown Brand

CNC Router Bit V‑Type 20° 0.5 mm is a V‑profile cutter designed for precision V‑grooving, engraving and chamfering. The tool features a 20° included angle and a 0.5 mm tip diameter that allows narrow, sharply defined cuts. It is intended for use with CNC routers and milling machines on materials compatible with the cutter geometry and substrate — for example wood, plastics, soft composites and circuit board materials when appropriate tooling speeds and feeds are used.

Advantages

The 20° V profile and 0.5 mm tip give consistent, narrow grooves and high-detail engraving with minimal material displacement. Its geometry provides predictable chamfering and a defined V shape for lettering, decorative grooves and profile work. The small tip diameter allows fine detail without requiring multiple passes, reducing setup time for small features while maintaining repeatability in CNC operations.

Suitable for

• Detailed signmaking and lettering
• V‑groove decorative work and chamfering
• Fine PCB routing and isolation milling on compatible laminates
• Precision engraving in wood, acrylic and other machinable plastics

Key specifications

• Tip diameter: 0.5 mm
• Included angle: 20°
• Tool type: V‑type router/engraving bit
• Intended use: V‑grooving, engraving, chamfering
• Machine compatibility: CNC routers and small milling machines capable of appropriate spindle speeds and feeds

How to use

Install the bit in the router collet ensuring correct runout and secure clamping. Select spindle speed, feed rate and depth of cut appropriate to the workpiece material and cutter size; reduce speeds and passes for fragile or heat‑sensitive materials. For fine engraving and narrow grooves, use shallow passes and verify toolpath in a test piece before full production. Monitor tool wear and check produced grooves for dimensional accuracy, adjusting feeds and speeds as needed.

Usage recommendations

Use appropriate dust extraction and eye protection when routing; select feed and speed settings that minimize heat build‑up to preserve the 0.5 mm tip. For best results on PCBs and laminates, use coolant or air blast as applicable and inspect bit condition frequently to avoid burrs or delamination.
