The Carmex Carbide Deep Groove Mill with Internal Coolant Bore is a precision 3 mm solid carbide grooving tool designed for deep grooves and long-hole milling. Built for engineers and machinists who demand exact profiles in tight-access areas, it delivers consistent performance and durability.

• Diameter: 3 mm cutting diameter for narrow grooves and tight tolerances
• Material: Solid carbide construction for superior rigidity and wear resistance
• Flutes: 6 spiral flutes behind efficient material removal and smoother cuts
• Cooling: Internal coolant bore delivers coolant directly to the cutting edge for heat control and extended tool life
• Deep-hole capability: Capable of machining deep holes up to 130 mm in depth
• Minimum groove diameter: Requires a groove diameter of at least 19.5 mm

This tool excels in creating deep, intricate grooves across a variety of workpieces. The through-bore coolant system provides a steady coolant flow to the cutting zone, helping to reduce heat, evacuate chips efficiently, and improve surface finish. The six-flute geometry enhances chip control and stability during long-reach operations, while the carbide body ensures lasting rigidity and precision in demanding materials. Ideal for precision groove work in automotive components, molds, and other metal parts where deep, narrow grooves are needed without compromising tool life or part quality.
