55° Deep Groove Flat End Mill - Extra-Long Reach Micro-Diameter Carbide Milling Cutter with Coated Neck for Steel (Hardened Alloy, Extended Flute)
55° Helix Angle Design: Optimized for high-efficiency chip evacuation and reduced vibration, ensuring smooth cuts in hardened steels, tool steels, and alloy metals.
Micro-Diameter Precision: Ultra-fine cutting edges (0.3 mm- 3 mm range) for intricate slotting, deep grooving, and micro-machining in tight spaces.
Coating: Heat-resistant coating extends tool life in high-temperature environments and resists abrasive wear.
Extended Neck & Flute: Extra-long reach with reinforced neck geometry for stability in deep cavity machining (e.g., injection molds, aerospace parts).
Tungsten Carbide Construction: Solid carbide body ensures rigidity and prevents deflection during high-speed CNC milling or heavy-duty cutting.
Engineered for precision and endurance, the 55° Deep Groove Flat End Mill redefines micro-machining in hardened materials. It's 55° helix angle balances cutting aggression and surface finish quality, making it ideal for slotting, profiling, and plunging into steels up to 55 HRC. The coated cutting edges withstand extreme heat, enabling dry or wet machining at speeds up to 20,000 RPM without edge degradation.
Designed for deep-pocket applications, the extended neck and flute length provide unmatched access to complex geometries in mold cavities, turbine blades, or medical implants. The ultra-fine micro-diameter range (0.3 mm- 3 mm) delivers micron-level accuracy, perfect for engraving, thread milling, or creating microfluidic channels.
Why Choose This End Mill?
