Hole Mill

Hole Mills are precision cutting tools designed for enlarging, finishing, or improving the accuracy of pre-drilled or cast holes. Unlike standard drills, which primarily create holes, hole mills are used to refine the diameter, improve surface finish, and maintain tighter dimensional tolerances. They are commonly manufactured from high-speed steel (HSS) or solid carbide, and often come with advanced coatings for enhanced wear resistance and tool life. Hole mills are widely used in automotive, aerospace, die & mold, and general engineering industries.

Key Features

  • High Precision Hole Finishing – Ensures accurate hole diameters with excellent roundness and straightness.

  • Improved Surface Quality – Provides smooth and consistent hole surfaces compared to standard drilling.

  • Rigid Design – Reduces chatter and tool deflection, ensuring consistent performance.

  • Material Options – Available in HSS, cobalt, and solid carbide, depending on the application.

  • Advanced Coatings – TiAlN, TiCN, or DLC coatings extend tool life and allow higher cutting speeds.

  • Versatile Applications – Suitable for steels, cast iron, stainless steel, non-ferrous metals, and hardened materials.

  • CNC & Conventional Use – Compatible with both modern CNC machining centers and traditional machines.

  • Enhanced Productivity – Reduces secondary finishing operations, saving machining time.
