99633 YG1 3/8" Carbide 4 Flute End Mill SQ CVD Diamond Coated .375" Diameter 0.875" Flute 2.50" Length .375" Shank D-Power

YG1 4 Flute CVD Diamond Coated End Mills

• Unmatched Wear Resistance for Abrasive Materials

  Machining graphite, plastics, and abrasive composites rapidly wears down standard tooling. The YG-1 D-POWER Series combats aggressive tool wear with an ultra-fine, ultra-hard diamond coating. This smooth coating drastically reduces friction and heat build-up at the cutting edge, helping maintain tight dimensional tolerances across long production runs.

  Precision 4-Flute Finishing Geometry

  Featuring a 30° helix angle and precision-ground 4-flute design, the D-POWER end mill provides high core rigidity and smooth chip evacuation. The 4-flute configuration is ideal for profile milling and finishing operations, leaving clean, mirror-like surface finishes on delicate and difficult-to-machine materials.

  Key Features & Benefits

  • Ultra-Hard Diamond Coating: Delivers superior film hardness and maximum resistance to abrasive wear.

  • 4-Flute Core Rigidity: Designed for finishing cuts, reducing chatter and maintaining tight tolerances.

  • 30° Helix Angle: Optimizes chip shear and evacuation in non-metallic and non-ferrous applications.

  • Micro-Grain Carbide Substrate: Provides maximum structural strength to prevent chipping or premature tool failure.

  • Superior Surface Finish: Smooth diamond film ensures fine surface quality on complex mold and die geometry.
