ITC Carbide End Mill Square Edge 164-ST - 2 Flute 30° Helix With Facet Relief - Micro - 1.1mm

The ITC Carbide End Mill Square Edge 164-ST is a precision micro-end mill designed for detail-heavy work. With a 1.1 mm diameter, a 2-flute design, and a 30° helix with facet relief, it delivers clean, accurate cuts in tight pockets and intricate profiles. Built for engineers, machinists, and hobbyists who demand reliable performance, this tool helps you achieve repeatable results in micro-machining tasks.

• Efficient chip evacuation with 2-flute geometry: The two-flute design promotes smooth chip clearance in micro features, reducing cutting forces and heat buildup for steadier cutting and better surface finishes.
• 30° helix with facet relief for stability and control: The combination of a 30° helix and facet relief lowers tool load and vibration, delivering consistent geometry on delicate profiles and extending tool life.
• Square-edge geometry for crisp, repeatable micro-features: Square cutting edges produce sharp corners and reliable dimensions in pockets and slots, helping you achieve precise micro-detail with every pass.

This end mill is built for reliability in demanding micro-machining applications. Its carbide construction provides durable, long-lasting performance across production runs, helping you reduce downtime, maintain tight tolerances, and achieve high-precision results with confidence.
