55 Degree Helix Angle Uncoated Solid Carbide Spherical End Mill with Razor-Sharp Cutting Edge for Aluminum Processing

Product Overview

This high-performance Uncoated Solid Carbide Spherical End Mill (commonly known as an Uncoated Lollipop Cutter) is engineered for precision profiling, undercutting, and back-chamfering in non-ferrous metals and polymers. Crafted from premium micro-grain tungsten carbide, this tool features a highly polished, uncoated razor-sharp edge that ensures crisp shearing action. Its unique sphere-on-a-neck geometry allows multi-axis machines to access complex 3D contours and confined internal cavities without workpiece interference.

Key Features

Razor-Sharp Cutting Edge: The uncoated (bright finish) design preserves the ultimate sharpness of the carbide edge, reducing cutting forces and delivering an exceptionally clean, burr-free cut.

Excellent Anti-Sticking & Mirror Finish: The mirror-polished carbide flutes minimize friction and prevent soft, gummy materials like aluminum or copper from welding to the tool, ensuring smooth chip evacuation.

360-Degree Undercutting & Clearance: With cutting edges wrapping around the back of the sphere and an elongated, reduced-neck section, this cutter easily reaches deep slots, reverse chamfers, and undercuts.

High-Precision Geometry: Precision-ground multi-flute configuration balance the chip load per tooth, effectively dampening chatter and maintaining strict dimensional tolerances at high spindle speeds.

Applications & Target Materials

Applications: High-gloss aluminum profiling, 5-axis mold contouring, back-side deburring, undercut milling, and internal porting/grooving.

Workpiece Materials: Aluminum alloys, pure aluminum, copper, brass, zinc, plastics, acrylic, nylon, and other non-ferrous materials.
