ADDISON HSS 8% Cobalt 4-Flute End Mill (S4 Series)

The ADDISON S4 Series end mills are high-performance industrial cutting tools engineered for demanding milling operations. Manufactured from premium High-Speed Steel (HSS) with an 8% Cobalt (M42 grade) content, these tools offer significantly higher heat resistance and hardness compared to standard HSS. This makes them ideal for machining tougher materials, including stainless steel, alloy steels, and high-tensile cast iron.

Key Features

  • 8% Cobalt (HSSE-Co8) Construction: Provides superior red-hardness, allowing the tool to maintain its cutting edge even at higher machining temperatures and increased feed rates.

  • 4-Flute Design (S4): The four-flute geometry offers a high level of tool rigidity and a finer surface finish. It is exceptionally well-suited for peripheral milling, finishing passes, and profiling.

  • Enhanced Tool Life: The addition of Cobalt reduces wear and prevents premature dulling when working with abrasive or heat-resistant workpiece materials.

  • Precision Ground Flutes: Features high-precision spiral flutes for efficient chip evacuation, reducing the risk of chip re-cutting and heat buildup.

  • Weldon Shank: Designed with a standard flatted shank for secure clamping in end mill holders, ensuring zero slippage during high-torque operations.
