The Carmex Carbide Groove Mill with Internal Coolant is a precision cutting tool built for machinists who demand clean, repeatable grooves in a variety of materials. Crafted from solid carbide, it combines durability with reliable performance, even in challenging machining conditions.

• Diameter: 7.8 mm with a groove width of 1.5 mm for precise groove profiles
• Material: Solid carbide construction for exceptional stiffness, wear resistance, and long tool life
• Internal coolant: Integrated cooling and chip evacuation through the flutes to maintain cutting efficiency and reduce heat
• Groove geometry: Precisely engineered groove shape for clean, accurate grooving and intricate profiles
• Minimum grooving diameter: Supports grooving diameters as small as 4 mm
• Flute design: 3–5 spiral flutes deliver smooth cutting action and effective chip control
• Versatility: One tool can handle both internal and external grooving with consistent results

This groove mill is designed to enhance accuracy and surface finish while extending tool life. The solid carbide core ensures rigidity and wear resistance, while the internal coolant and flute-through cooling optimize chip removal and heat management. With its precise groove geometry and multi-flute design, it delivers dependable performance for detailed grooves, keyways, and internal recesses—making it a reliable choice for CNC operators, toolmakers, and production shops aiming for consistent, high-quality results.
