The Walter Prototyp Proto·max Ultra ball-nose end mill, specially engineered for efficient machining of hard materials, offers enhanced machining performance and tool life, even when machining hard ISO-H materials.
The end mills come in two different diameter ranges: the standard versions from 3 to 12 mm diameter and the mini versions for small to extremely small contours, ranging from 0.1 to 2.5 mm.
For the smaller diameter range, the Proto·max Ultra's reduced neck and its reach of up to 10xD are beneficial for the machining of deep cavities. This results in excellent concentricity properties, which are essential at the high speeds achieved by small tool diameters.
It's TiAlSiN-based coating, known as TAS for short, is highly heat-resistant, leading to longer tool life when machining hard materials.
Features:
- TiAlSiN-based coating
- Optimized geometry for stabilizing the cutting edges
- All diameters have two cutting edges and a helix angle of 30-deg.
- Efficient machining of hard material
- Excellent concentricity properties
Applications:
- Semi-roughing and roughing
- Semi-finishing and fine-finishing
