Meet the Carmex Carbide Groove Mill with Internal Coolant — a high-precision cutting tool crafted for machinists and fabricators who demand clean, repeatable grooves across a range of materials. Built from solid carbide, this mill delivers exceptional strength, durability, and longevity even in demanding grooving applications.

• Diameter: 9.8 mm
• Groove width: 1.50 mm
• Material: Solid carbide for rigidity and wear resistance
• Flute count: 3–5 spiral flutes for efficient cutting and chip evacuation
• Internal coolant: Through-flute cooling and chip evacuation to sustain cutting performance
• Grooving capability: Suitable for both internal and external grooving with a single tool
• Minimum grooving diameter: Supports grooving diameters as small as 4 mm
• Groove geometry: Precisely engineered grooves for clean, accurate profiles
• Material versatility: Effective on a variety of metals and alloys, including tough or high-precision workpieces

The internal coolant system promotes efficient chip removal and cooler cutting zones, which translates to longer tool life and steadier performance in challenging conditions. The precise groove geometry enables tight tolerances and pristine profiles, making it ideal for intricate designs and profiles—from keyways and channels to decorative or functional grooves. With the ability to perform both internal and external grooving using the same tool, it simplifies setups and reduces tooling inventory while delivering consistent results.
