2mm 2-Flute Uncoated Solid Carbide Ball Nose End Millfor Aluminium & Non-Ferrous 3D Surface Machining
Uncoated (bright-polished) ball nose end mills with 2 flutes are specifically optimised for high-speed 3D contouring in aluminium alloys, copper, graphite, and soft non-ferrous materials. The mirror-polished flute surface prevents built-up edge (BUE) that can degrade surface finish in soft metals. Large chip gullets ensure complete swarf evacuation even at spindle speeds above 20,000 RPM. Ideal for electrode machining (EDM graphite) and aluminium aerospace structural components.

Where This Tool Excels
R1mm Uncoated 2F — Recommended Applications
- ▸Micro-mould texture and fine engraving
- ▸Medical implant surface contouring
- ▸Watch case and jewellery component 3D finishing
- ▸Electrode finishing for micro-EDM
Machining Tip: R1mm is a micro ball — spindle runout must be ≤ 0.002mm. Use ER collet with ≤ 3µm accuracy. In aluminium alloy, step-over 3–5% of D1 for mirror finish. Scallop height at 5% step-over ≈ 0.0025mm.
3D Finishing Reference
Scallop Height vs Step-Over — R1mm
Residual scallop height (cusps) between adjacent tool paths, calculated for R1mm ball nose:
| Step-Over | Step-Over mm | Scallop Height (µm) | Typical Ra (µm) |
|---|---|---|---|
| 2% D1 | 0.04 | 0.2 | ≈ 0.04 |
| 5% D1 | 0.10 | 1.3 | ≈ 0.25 |
| 8% D1 | 0.16 | 3.2 | ≈ 0.64 |
| 10% D1 | 0.20 | 5.0 | ≈ 1.00 |
| 15% D1 | 0.30 | 11.3 | ≈ 2.26 |
| 20% D1 | 0.40 | 20.2 | ≈ 4.04 |
h = R − √(R² − (ae/2)²). Actual Ra depends on feed rate, chip load, and material.

Coating Performance
Uncoated — Why It Works for Ball-End Machining
- ▸Mirror-polished flute — zero aluminium adhesion on ball profile
- ▸Eliminates built-up edge (BUE) during high-speed aluminium contouring
- ▸Large chip gullets for clean swarf evacuation at 20,000+ RPM
- ▸Ideal for graphite electrode and EDM insert 3D profiles
- ▸Use with air blast or light oil mist — no flood coolant needed
