Product Overview

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.

Key Features

Optimized for Hardened & Heated Steel - High-performance carbide substrate resists thermal deformation with specialized coatings (TiAlN, AlCrN, or DLC) that reduce heat buildup & extend tool life
Lollipop (Barrel/Toroidal) Geometry - Larger contact area than ball nose end mills enables higher material removal rates (MRR) and reduces step-over marks for smoother surface finishes
Variable Helix & Uneven Flute Spacing - Minimizes vibration & chatter in high-hardness materials while improving chip evacuation in deep-pocket milling
Precision-Ground Cutting Edges - ± 0.005mm tolerance for ultra-fine finishes with sharp or radiused edge options to prevent chipping in interrupted cuts

Coating Options

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

Typical Applications

Mold & Die Making

Aerospace Components

Medical Implants

Automotive Forging Dies
