2-Flute Polished Solid Carbide Ball Nose End Mill Overview
This 2-flute polished solid carbide ball nose end mill is designed for three-dimensional contouring, cavity machining and curved-surface finishing in aluminum and other non-ferrous materials. Sharp cutting edges reduce cutting resistance, while the polished flute surface helps limit chip adhesion and supports smooth evacuation during continuous CNC machining. Standard and extended-length configurations cover R0.5–R10, Ø1–Ø20 mm cutting diameters and 50–150 mm overall lengths, giving distributors and tooling suppliers a practical range for general finishing, deeper profiles and replacement-tool requirements.
Geometry for Aluminum Finishing
Open Two-Flute Geometry
Two flutes provide chip space for aluminum machining and help reduce chip recutting during contour finishing.
Ball Nose Surface Contact
The full-radius cutting profile follows curved, blended and free-form surfaces with progressive tool engagement.
Key Features & Benefits
Polished Flute Surface
A smooth flute finish helps reduce aluminum adhesion and supports consistent chip flow.
Sharp Cutting Edge
Sharp edge preparation lowers cutting resistance in soft and adhesive non-ferrous materials.
Smooth 3D Toolpaths
Ball-end geometry supports continuous finishing across curved and complex surfaces.
Broad Size Coverage
Standard, long-reach and extended-length sizes support varied profile depths and holder clearances.
Recommended Applications
Select the radius, flute length and overall length according to the surface curvature, required reach, holder clearance and finishing allowance.

Ball Nose Size Selection
- Ball Radius: Select R according to surface curvature, fillet size and required scallop height.
- Flute Length: Use only the length required to reach the feature while maintaining sufficient rigidity.
- Overall Length: Longer 75–150 mm tools require reduced engagement and stable low-runout toolholding.
- Effective Diameter: Calculate spindle speed from the actual ball-nose contact diameter where possible.
- Chip Evacuation: Use suitable air blast, mist or coolant to prevent aluminum chip adhesion and recutting.
