ITC Carbide End Mill Square Edge 164 - 30° Helix With Facet Relief - Micro - 0.4mm

The ITC Carbide End Mill Square Edge 164 is a precision micro end mill designed for detailed, small-diameter milling. With a square cutting edge and a 0.4 mm diameter, it features a 30° helix and facet relief to promote efficient chip evacuation and stable cutting in tight-feature work. This combination helps maintain clean edges and consistent results even on challenging micro-machining tasks.

Ideal for engineers, shop floors, and serious hobbyists who require reliable micro-machining performance, this tool is built to handle intricate detail work with confidence and repeatable accuracy.

• Efficient chip evacuation with 30° helix and facet relief: The geometry directs chips away from the cut and reduces rubbing, helping cooler cuts, fewer built-up edges, and smoother finishes on tiny features.
• Stable, precise micro‑machining performance: Rugged carbide construction and optimized geometry minimize deflection, delivering consistent dimensions and reliable results during delicate detail work.
• Long tool life under demanding micro-work: Durable edges and relief design reduce wear, extending tool life and enabling more productive runs with fewer tool changes.

This end mill supports faster, more predictable workflows by delivering clean edges, stable cuts, and repeatable results at micro scales. It helps reduce rework, shorten cycle times, and improve overall part quality across tight tolerances and intricate features.
