HRC55 12mm End Mill Solid Carbide U Grrove Shape High Efficiency Endmill

Introduction:

The U-groove end mill (also called a radius edge end mill or full-radius end mill) is a specialized solid carbide cutter designed for high-speed, high-efficiency machining of grooves, slots, and contours with smooth bottom finishes.

Features:

U-Shaped Cutting Edge (Concave Radius)

• • Produces rounded grooves (unlike flat-bottom end mills).

  • Ideal for t-slot cutting, undercuts, and semi-circular channels.

  • Reduces stress concentration in machined parts.

Solid Carbide Construction

• • High rigidity & wear resistance for long tool life.

  • Suitable for hard materials (steel, stainless, titanium, hardened alloys).

High-Efficiency Design

• • Optimized flute geometry for fast chip evacuation.

  • Reduced vibration for better surface finish.

Coating Options (Optional)

• • TiAlN/AlCrN – For high-heat applications (stainless steel, Inconel).

  • DLC (Diamond-Like Carbon) – For non-ferrous metals (aluminum, copper).

Multi-Flute Options (2/3/4 Flutes)

• • 2-3 Flutes – Best for aluminum, plastics (chip clearance).

  • 4 Flutes – Smoother finish in steel & tough alloys.

Typical Applications:

• ✔ T-Slot & Dovetail Machining (milling precise grooves).
  ✔ Mold & Die Making (concave radii, undercuts).
  ✔ Aerospace & Automotive Components (lightweight structural slots).
  ✔ Medical Implants & Precision Engineering (smooth-radius features).
