Product Overview: DHF Tungsten Carbide Deep-Slot Corner Radius End Mill – UNER Series

【Product Features & Why We Recommend It】

  • Deep-Slot Machining Solution: Specifically designed with a Neck-Down and micro-diameter configuration, recommended for machining narrow and deep grooves — effectively avoiding interference and solving the common dilemma where short-flute tools cannot reach and long-flute tools lack sufficient rigidity.
  • Premium Substrate Selection: Manufactured with SMG0.2 ultra-fine grain tungsten carbide, providing superior cutting edge wear resistance and resistance to micro-chipping when machining high-hardness materials up to HRC60.
  • Corner Radius Protection Design: The ball nose (R-nose) geometry is not only capable of curved surface machining, but is most recommended for flat surface operations to protect the cutting tip — preventing corner chipping when machining hardened steel and extending tool change intervals.
  • Cutting Stability: The 35° helix angle combined with precision geometry delivers consistent cutting feel, helping to maintain fine workpiece surface quality.

【Machining Applications】

  • Primary Use: Micro mold deep-slot machining, precision R-nose profiling, and clearance milling.
  • Recommended Work Materials:
    • P/H-Class: General structural steel through hardened heat-treated steel (within HRC60).
    • M/S-Class: Difficult-to-machine stainless steel, titanium alloys, or nickel-based superalloys, with stable anti-adhesion performance.
    • K-Class: High-hardness cast iron and gray iron.
