Nine9 MCC Mill for threading and deburring

The Nine9 MCC (Minimum Consumable Cutting) tool is an innovative, indexable cutting solution designed for efficient deburring, threading, and chamfering operations in CNC machining. Developed by Nine9 Cutting Tools, the MCC tool emphasizes sustainability by minimizing carbide usage—each insert utilizes less than 5% of the carbide material compared to traditional solid carbide tools—without compromising performance.

Key Features:

  • Multi-Functional Design: Capable of front and back deburring, threading, and grooving in a single operation, enhancing machining efficiency.

  • Optimized Geometry: Equipped with 6-flute inserts, the MCC tool allows for higher feed rates and superior surface finishes. The fully ground insert geometry ensures burr-free results.

  • Versatility: Available in various angles—60° and 90° for deburring, and 55° and 60° for threading—to accommodate different machining requirements.

  • Compact Size: Designed for operations in narrow spaces, with insert diameters starting from 5mm, making it suitable for fine hole deburring and threading applications.

  • Material Compatibility: The MCC tool is effective on a range of materials, including hardened steels up to HRC60, carbon steel, alloy steel, cast iron, and non-ferrous metals like aluminum and copper.

Sustainability Focus:

The MCC concept aligns with sustainable manufacturing practices by reducing material consumption and carbon emissions. By utilizing indexable inserts, the tool extends the lifespan of the holder and decreases the frequency of tool replacements, contributing to cost savings and environmental benefits .​
