The Carmex Carbide Deep Groove Mill with Internal Coolant Bore is a high‑rigidity, solid carbide grooving tool designed for engineers and machinists who need precise, deep internal grooves. Built for demanding metalworking tasks, it delivers dependable performance and efficient heat management.

• 6 spiral flutes: Provides smooth cutting and effective chip evacuation for long, deep grooves.
• Internal coolant bore: Delivers coolant directly to the cutting edge to reduce heat, extend tool life, and improve chip control.
• Solid carbide construction: Offers exceptional rigidity, wear resistance, and longevity in demanding applications.
• Deep groove design: Optimized for machining grooves in deep holes, up to 130 mm deep, with consistent profiles.
• Minimum groove diameter: Requires a groove diameter of at least 19.5 mm to maintain structural integrity and cutting performance.

This tool combination—deep reach, direct cooling, and a robust carbide body—helps you achieve cleaner surfaces, tighter tolerances, and fewer interruptions during high-precision grooving tasks. Ideal for applications where deep internal grooves are essential, such as intricate internal channels and housings across automotive, moldmaking, and aerospace components.
