Introduction:

A 20mm dovetail customized carbide end mill with 4 flutes and a corner radius (bull nose) is a specialized cutting tool designed for machining dovetail grooves, undercuts, and other angled profiles in hard materials like steel, stainless steel, and hardened alloys.

Features:

Diameter: 20mm (shank size may vary based on holder requirements).

Tool Type: Dovetail End Mill – Designed to cut angled sides (typically 45°, 60°, or custom angles).

Material: Solid Carbide – Ensures high wear resistance, rigidity, and heat resistance.

Flutes: 4 Flutes – Provides a balance between chip evacuation and surface finish.

Corner Radius (Bull Nose):

• • • A small radius at the tool’s corners improves edge strength, reducing chipping.

    • Helps in achieving smoother finishes in contouring and side milling.

• • Coating Options (if applicable):

    • TiAlN, AlTiN, or DLC for improved tool life in tough materials.

    • Uncoated for general-purpose machining.

Common Applications:

• • Machining dovetail slides (e.g., machine tool ways, industrial fixtures).

  • Undercutting and chamfering in molds & dies.

  • 3D profiling in aerospace and automotive components.

  • Hard milling (if using premium carbide grades).Customization Options:

  • Dovetail Angle: 30°, 45°, 60°, or custom angles.

  • Shank Type: Straight, Weldon, or HSK.

  • Helix Angle: High helix for better chip evacuation.

  • Special Geometry: Variable pitch for reduced vibration.
