Metric Long Reach End Mills: Deep Precision at ToolsEngg.com
Metric long reach end mills deliver extended cutting depth for complex CNC milling in narrow cavities and ribs. ToolsEngg.com stocks these high-performance carbide tools, ideal for mold making, aerospace, and automotive exporters seeking superior finish and efficiency.
What Are Metric Long Reach End Mills?
Sized in millimeters (3mm-25mm diameters), these end mills feature flute lengths up to 12xD with reduced necks for clearance. Typically 4-6 flutes, 38°-45° helix angles, and coatings like AlCrN or nACo ensure chip evacuation and heat resistance up to 60 HRC. ToolsEngg.com offers variable pitch designs to minimize vibration in trochoidal and high-speed machining.
Key Advantages
Extended reach accesses deep features without collisions, reducing setups by 40% and enabling aggressive feeds (200-400 mm/min). Necked shanks maintain rigidity, preventing deflection for tolerances under 0.01mm. Polished flutes and nano-coatings extend life 3x in dry conditions, cutting costs for high-volume production.
Applications in Manufacturing
Perfect for injection molds, die cavities, engine ports, and medical implants requiring precise 3D contouring. They excel in ramping, helical interpolation, and finishing hardened tool steels or titanium in export-oriented shops.
