HTPM series milling cutters have unequal flute spacing (variable pitch) and multiple helix angles (35° and 37°) to reduce chatter and harmonics, for improved stability and better finishing. This also optimizes chip formation and chip evacuation. These 4-flute end mills feature a spherical ball end. Aluminum Chromium Nitride (Hybrid AlCrN) coating reduces wear and increases …
