The Carmex Carbide Groove Mill with Internal Coolant is a precision grooving tool designed for machinists who demand clean, accurate grooves in a range of materials. Built for both internal and external grooving, it delivers reliable performance even in challenging conditions.

• Size: Ø7.8 mm cutting diameter with a 2.0 mm groove width for precise, narrow grooves.
• Material: Solid carbide construction provides exceptional rigidity, wear resistance, and long tool life.
• Internal coolant: Coolant channels run through the flutes, delivering efficient chip evacuation and cooling to maximize performance.
• Flute configuration: 3–5 spiral flutes optimized for smooth cutting and controlled chip formation.
• Groove geometry: Precisely engineered groove profile ensures clean, accurate grooving and the ability to reproduce intricate designs.
• Versatility: Suitable for internal and external grooving with a single tool, reducing tool changes and setup time.
• Material compatibility: Effective across a variety of materials, with consistent results when machining different alloys.

The combination of solid carbide hardness and internal coolant delivers consistent, reliable performance in demanding applications. The tool maintains sharpness longer, minimizes heat buildup, and yields tight tolerances on groove dimensions. Its precise groove geometry supports intricate profiles, making it ideal for precision shafts, sleeves, and other components requiring clean, repeatable grooves. By enabling both internal and external grooving with one tool, it simplifies tooling logistics and can boost milling efficiency on compatible machines.
