Lollipop End Mills CNC Cutting with coating for heated steel

Introduction:

The AMG Lollipop End Mill (also called barrel end mills or toroidal cutters) is a specialized solid carbide CNC cutting tool designed for 3D contouring, mold/die machining, and complex surface finishing in hardened steels (HRC 45-65), aerospace alloys, and heat-resistant materials. Its unique spherical or radiused cutting profile allows for smooth transitions and reduced step marks compared to standard ball nose end mills.

Features:

Optimized for Hardened & Heated Steel

• High-performance carbide substrate resists thermal deformation.

• Specialized coatings (TiAlN, AlCrN, or DLC) reduce heat buildup & extend tool life.

Lollipop (Barrel/Toroidal) Geometry

• Larger contact area than ball nose end mills → higher material removal rates (MRR).

• Reduces step-over marks for smoother surface finishes.

• Ideal for deep-cavity machining (undercuts, fillets, 5-axis sculpting).

Variable Helix & Uneven Flute Spacing

• Minimizes vibration & chatter in high-hardness materials.

• Improves chip evacuation in deep-pocket milling.

Coating Options for Extreme Conditions

• TiAlN (Titanium Aluminum Nitride) – Best for hardened steel (HRC 50+).

• AlCrN (Aluminum Chromium Nitride) – Superior oxidation resistance for stainless steel & Inconel.

• DLC (Diamond-Like Carbon) – Low-friction coating for non-ferrous & graphite.

Precision-Ground Cutting Edges

• ±0.005mm tolerance for ultra-fine finishes.

• Sharp or radiused edge options (prevents chipping in interrupted cuts).

Typical Applications:

✔ Mold & Die Making (Complex 3D cavities, cores, EDM electrode finishing)
✔ Aerospace Components (Titanium, Inconel, turbine blades)
✔ Medical Implants (Precision contoured surfaces)
✔ Automotive Forging Dies (Hardened tool steel machining)
✔ Energy Industry (Heat-resistant alloy components)
