• Neck Design: Long neck for extended reach and improved access in deep pockets
• Back Draft Type: Long neck/back draft geometry to enhance stability and reduce chatter
• Helix Angle: 30° for efficient chip evacuation and smooth cutting
• Material: Ultra-fine grain carbide for strength and wear resistance
• Center Cutting: Yes, enabling plunging and slotting operations
• Hardness Capability: Suitable for machining hard materials up to HRc70
• Flexibility: Geometry supports effective neck length positioning aligned with rake angle for different machining setups

This end mill is purpose-built for micro-machining where precision matters: small-diameter slots, tight radii, and smooth edge finishing on hardened workpieces. The combination of a tiny 0.4 mm diameter with a corner radius of 0.1 mm delivers precise fillets and clean wall transitions, while the 30° helix helps evacuation of chips in confined spaces. The long neck and back-draft design contribute to tool stability, reducing vibration and chatter when cutting into deep grooves or angled surfaces. With center-cutting capability, you can plunge directly into the workpiece and then resume precise contouring with consistent results. Its carbide construction ensures durability and wear resistance even when machining hard materials up to HRc70, making it a reliable choice for challenging applications.
