Tungsten Carbide End Mill Cutting Tool Custom Dovetail Milling Cutter

A custom dovetail milling cutter made from tungsten carbide is a specialized cutting tool designed for machining precise dovetail grooves or undercuts in materials like steel, aluminum, titanium, or hardened alloys.

• Tungsten Carbide (Uncoated):
  • High hardness (~90-94 HRA) for wear resistance.
  • Better heat resistance than HSS but may generate more friction than coated tools.
  • Ideal for applications where coatings could interfere (e.g., non-ferrous metals, graphite, or when a polished edge is needed).

• Standard Angles: 45°, 60°, or 90° (custom angles available).
• Cutting Edge Profile:
  • Sharp, uncoated edges for clean cuts in aluminum, brass, or plastics.
  • Optional polished flutes for improved chip evacuation in gummy materials.

• Diameter (D): 3mm-25mm (or larger, depending on shank).
• Shank Diameter: Matches tool diameter or undersized for clearance.
• Flute Count:
  • 2 Flutes: Best for aluminum, plastics (high chip clearance).
  • 3-4 Flutes: Smoother finish in steel or cast iron (but requires proper chip evacuation).
• Cutting Length (L): Short (for rigidity) or extended (for deep slots).
• Helix Angle:
  • Low (15°-30°): For steel, titanium.
  • High (35°-45°): For aluminum, non-ferrous metals.

• Better for Non-Ferrous Metals: Coatings like TiN/TiAlN can sometimes adhere to aluminum.
• Cost-Effective: Uncoated tools are cheaper than coated ones.
• Sharp Edge Retention: Some high-precision applications (e.g., graphite machining) prefer uncoated tools for a keener edge.

• Aluminum, Brass, Copper (no coating reduces material adhesion).
• Plastics & Composites (prevents melting/gumming).
• Graphite Electrode Machining (uncoated carbide resists edge buildup).
• General-Precision Dovetail Slots where coating is unnecessary.

• Advanced grinding machines: All of our grinding machines are WALTER and SAACKE brands.
• Advanced inspection machines: We have ZOLLER, OMEGA, PG1000, etc. For inspecting each carbide tools.
• Fast feedback: we offer 24 hours online service
• Strict quality control system:
  • Raw material inspection
  • Semi-finished product inspection after production
  • Final inspection after coating (pre-shipment check)
