Product Overview

this high-performance Coated Solid Carbide Spherical End Mill (commonly known as a Lollipop Cutter or Undercut Ball End Mill) is a premier choice for multi-axis and complex geometry machining. Featuring a premium micro-grain carbide substrate and an advanced heat-resistant nano-coating, it is specially designed for undercutting, back-chamfering, and internal cavity profiling where standard ball nose end mills cannot reach.

Key Features

360-Degree Cutting Capability: The unique spherical head features cutting edges that wrap around the back towards the neck, enabling seamless back-chamfering, undercutting, and complex deburring.

High-Performance Nano-Coating: The bronze-colored nano-coating provides excellent thermal stability and oxidation resistance, effectively insulating cutting heat and extending tool life in demanding materials.

Optimized Neck Clearance: Engineered with a reduced shank/neck diameter to provide superior clearance for deep cavity machining while maintaining high rigidity to minimize deflection and chatter at high speeds.

Exceptional Surface Finish: The precision-ground multi-flute geometry ensures smooth chip evacuation and a superior surface finish during complex 3D mold and die profiling.

Applications & Target Materials

Applications: 5-axis mold contouring, undercut milling, back-side deburring/chamfering, and profiling of internal porting or sealing grooves.

Workpiece Materials: Mold steels, alloy steels, carbon steels, pre-hardened steels (up to HRC 55-60), stainless steel, and cast iron.
