The Carmex Carbide Groove Mill With Internal Coolant (12mm x 2.00mm) is a precision grooving tool designed for machinists who demand clean, accurate grooves in challenging materials. Built from solid carbide and equipped with an internal coolant system, it delivers dependable performance for both internal and external grooving tasks.

• Cutting Diameter: 12 mm with a 2.00 mm groove width, enabling precise grooving across a range of applications.
• Material: Solid carbide for high rigidity, wear resistance, and long tool life.
• Flute Configuration: 3–5 spiral flutes optimized for efficient cutting and smooth finishes.
• Internal Coolant: Through-flute cooling and chip evacuation improve heat management and extend tool life.
• Grooving Versatility: Suitable for internal and external grooving, with capability for grooving diameters down to 4 mm.
• Precision Groove Geometry: Carefully engineered geometry to produce clean, accurate grooves and intricate profiles.

This groove mill helps you achieve tight tolerances and consistent finishes with reduced tool wear. The internal coolant minimizes heat and chip buildup, supporting longer tool life and fewer rework cycles in demanding materials. By handling both internal and external grooving in a single tool, it streamlines setups and improves workflow, delivering repeatable grooves for shafts, housings, and other precision components—even in tight bore areas.
