Description
The ITC Carbide End Mill Square Edge 164-ST is a precision micro-end mill designed for accurate, detailed cuts in tight spaces.
It’s built for engineers, machinists, and hobbyists who demand reliable performance in micro-machining applications, delivering clean corners and consistent dimensions on small features.
- Micro‑scale geometry for tight tolerances: The 1.7 mm diameter with square-edge cutting geometry maintains sharp corners and precise dimensions, ensuring repeatable results on intricate micro features.
- 2‑flute design with 30° helix: Optimized for efficient chip evacuation and smoother cutting entry, this geometry reduces cutting forces and enhances stability during micro operations.
- Facet relief for smooth finishes and longer tool life: The facet relief minimizes rubbing and heat buildup, promoting consistent surface finishes and extended tool life in demanding profiles.
Using the ITC 164-ST micro end mill helps you streamline production with accurate cuts and minimal rework, improving throughput and reliability across intricate parts. Its carbide construction delivers durable, consistent performance under demanding micro-machining tasks, making it a dependable choice for both production runs and prototyping.
