- Flutes: 2 flutes for efficient chip evacuation and rigidity
- Helix angle: 30° for smooth cutting and effective chip removal
- Center cutting: Yes, enabling plunging and pocketing
- Geometry: Corner radius with long-neck, back-draft design to reduce vibration and chatter
- Material compatibility: Suitable for machining high-hardened materials up to HRc70
- Flexibility: Long-neck/back-draft construction supports effective neck-length adjustments via rake angle for different operations
This end mill delivers precise edge quality with a compact 2 mm diameter and a 0.3 mm corner radius, ideal for creating smooth transitions and reducing wear on both tool and workpiece. The long-neck design provides added reach for deep pockets and stepped contours, while the back-draft geometry contributes to stability and reduced chatter during aggressive cuts. The 30° helix promotes efficient chip evacuation, helping maintain clear cuts when machining hard alloys close to HRc70. Center cutting capability broadens its use to plunging, slotting, and pocketing tasks, making it a versatile choice for intricate milling work and demanding production environments.
