Product Function

Our HRC70 Square Carbide End Mill is engineered for the most demanding CNC milling operations. Designed primarily for side milling, slotting, and profile milling, this tool excels in removing material efficiently.
Crucially, the reinforced corner protection design ensures stability when entering the workpiece, making it the ideal solution for machinists needing to cut extremely hard materials or difficult-to-machine superalloys without the risk of premature corner chipping.

Product Features

  • Corner Protection Design: Features a specialized micro-geometry at the cutting tips. This "Corner Protection" significantly reduces the risk of chipping (breakage) at the weakest point of the tool, ensuring stable machining in high-hardness materials.
  • Superior Hardness (HRC70): Made from ultra-fine micro-grain tungsten carbide, offering exceptional wear resistance and rigidity.
  • Special Advanced Coating: Features a proprietary high-heat resistant coating that reduces friction and prevents built-up edge (BUE), crucial for machining sticky materials like Titanium and Stainless Steel.
  • Wide Material Applicability: Perfectly suited for Titanium Alloys, Heat-Resistant Superalloys (Inconel), Stainless Steel (304/316), Mold Steel, and Hardened Carbon Steel.
  • Vibration Absorption: The flute geometry is optimized to minimize vibration and chatter, ensuring a superior surface finish.

FAQ

Q1: What is "Corner Protection" and why do I need it? A: Corner protection is a reinforced geometry design at the tip of the flutes. It prevents the sharp corners from chipping instantly when they touch hard materials (like HRC60+ steel or Titanium). It maintains the "square" cut profile while drastically increasing durability.
Q2: Can this HRC70 end mill cut Aluminum? A: While it is hard enough, we do not recommend it. This tool has a coating designed for heat resistance in hard metals. For Aluminum, we recommend our uncoated or DLC-coated bright finish end mills to prevent sticking.
Q3: What is the delivery time for the items in the specification table? A: All items listed in the table are currently in stock. Orders usually ship within 24-48 hours after payment confirmation.
Q4: Do you offer OEM/ODM services? A: Yes, we can manufacture custom tools based on your drawings or specific requirements (e.g., specific corner radius or taper angles).
