Meet the Carmex Carbide Groove Mill with Internal Coolant — a precision cutting tool designed for internal and external grooving tasks. Built for machinists and production environments that demand clean grooves, repeatable results, and reliable performance under demanding conditions.

• Material: Solid carbide construction delivers high stiffness, wear resistance, and long tool life in a variety of materials.
• Internal coolant: Integrated coolant channels run through the flutes to improve cooling and chip evacuation for steadier cuts.
• Groove capability: Optimized for grooving with diameters as small as 4 mm, enabling precise, tight-profile grooves.
• Flute configuration: 3–5 spiral flutes that balance strength, chip clearance, and finishing capability.
• Dual functionality: Designed to handle both internal and external grooving with the same tool, reducing setup changes and tooling inventory.
• Cutting geometry: Precisely formed groove geometry for clean, accurate profiles and tight tolerances.
• Durability: Robust carbide body stands up to demanding machining conditions and provides consistent performance over time.

This groove mill enhances efficiency by maintaining cooler cuts, promoting longer tool life, and delivering repeatable surface finishes. The combination of internal coolant, precise groove geometry, and a versatile 4 mm capability makes it a dependable choice for intricate grooving tasks and high-mix production, helping you achieve clean grooves with fewer passes and less downtime.
