Description
The ITC Carbide End Mill Ball Nose 155 is a precision micro-milling tool designed for detailed work at small scales. With a 1.2 mm diameter and a ball-nose tip, this 2-flute carbide end mill delivers smooth, rounded features on complex surfaces, making it ideal for micro-detailing, prototyping, and fine engraving.
Designed for reliability, the tool combines a 30° helix with facet relief to optimize chip evacuation, reduce cutting forces, and improve cutting stability—helping you maintain tight tolerances and consistent finishes across delicate work.
- Ball Nose Geometry for Complex Contours: Produces smooth, accurate rounded features on tight curves, reducing the need for extra finishing and enabling precise 3D detailing.
- 30° Helix with Facet Relief: Enhances chip evacuation and lowers cutting forces, delivering steadier cuts and improved surface quality in micro-milling operations.
- Durable Micro-Scale Carbide with 2 Flutes: Provides rigidity and predictable performance for micro-milling, helping extend tool life and minimize downtime.
This end mill is built for professionals and enthusiasts who demand consistent, high-precision results. By combining precise ball-nose geometry, optimized helix and relief, and durable carbide construction, it supports faster workflows, fewer reworks, and reliable finishes on intricate micro-features across a range of materials.
