3. Engineering Dimensions & Geometry
| Parameter | Value |
|---|---|
| Nominal diameter | 1/4 in (6.35 mm) |
| Number of flutes | 2 |
| Corner radius | Ball nose (full radius R3.175 mm) |
| Typical shank diameter | 1/4 in (6.35 mm) |
| Helix angle | 30° typical |
| Overall length | Standard series length |
4. Grade Details & Characteristics
- Sub-micrograin solid carbide substrate for high hardness and edge strength.
- Advanced PVD multi-layer coating reduces heat and crater wear.
- Smooth flute surface lowers friction and improves chip evacuation.
- Centre-cutting capable design for direct plunge and ramping.
5. Grade Comparison Matrix
| Grade Class | Wear Resistance | Heat Resistance | Typical Use |
|---|---|---|---|
| Uncoated carbide | Moderate | Low | Aluminium, plastics |
| General coated | Good | Moderate | General steels |
| Premium coated (TC) | Very high | High | Steel, stainless, cast iron |
6. Chipbreaker Profile
- Two-flute open-gullet geometry for generous chip space.
- Ball-nose cutting edge for continuous 3D surface generation.
- Polished flute margins to reduce built-up edge and friction.
- Strong core for stable high-speed machining.
7. Recommended Applications & Materials
| Material Group | Suitability |
|---|---|
| Carbon & alloy steels | Excellent |
| Stainless steels | Good |
| Cast iron | Good |
| Aluminium alloys | Suitable with adequate coolant |
| Titanium & high-temp alloys | Moderate (reduce speeds) |
8. Application Map by Operation
| Operation | Suitability |
|---|---|
| 3D profiling / finishing | Recommended |
| Contour & copy milling | Recommended |
| Pocketing & slotting | Suitable |
| Plunging / ramping | Suitable (centre-cutting) |
| Heavy roughing | Limited |
9. Recommended Cutting Conditions
Starting values for stable setups using coolant; reduce speeds for longer overhangs.
| Material | Vc (m/min) | fz (mm/tooth) | ap max | ae |
|---|---|---|---|---|
| Low-alloy steel | 100–140 | 0.04–0.10 | 1.0 × D | 0.1–0.2 × D |
| Stainless steel 304 | 60–90 | 0.03–0.08 | 0.8 × D | 0.08–0.15 × D |
| Grey cast iron | 120–160 | 0.05–0.12 | 1.2 × D | 0.15–0.25 × D |
| Aluminium alloy | 250–400 | 0.05–0.15 | 1.0 × D | 0.1–0.3 × D |
10. Operating Guidelines
- Rigid toolholder and minimum overhang improve accuracy and tool life.
- Calculate RPM = (Vc × 1000) / (π × D).
- Use coolant or compressed air to clear chips and control heat.
- Prefer climb milling for better surface finish and lower cutting forces.
- Inspect edges for chipping or wear before critical finishing passes.
11. Toolholder Compatibility
- ER collet chucks and spring collets.
- Endmill holders / Weldon flat side-lock holders.
- Shrink-fit and hydraulic chucks for high-speed applications.
- Milling arbors with 1/4 in bore or collet size.
