The Carmex Carbide Deep Groove Mill with Internal Coolant Bore is a precision solid carbide grooving tool engineered for deep-hole work, delivering consistent, accurate grooves up to 130 mm deep. Built for machinists and manufacturers who demand durability and tight tolerances, it thrives in demanding environments where clean, deep channels matter.

• Diameter: 4 mm cutting diameter for compact, high-precision grooves.
• Depth capability: Designed for deep grooves up to 130 mm deep to maximize material removal in a single setup.
• Minimum groove diameter: Requires a minimum groove diameter of 19.5 mm.
• Flute design: 6 spiral flutes to promote smooth cutting and efficient chip evacuation.
• Coolant system: Internal coolant bore delivers coolant directly to the cutting edge, optimizing temperature control and chip removal.
• Material and construction: Solid carbide construction for high rigidity, wear resistance, and long tool life.

With its internal coolant bore and six-flute geometry, this tool minimizes heat buildup and enhances surface finish while extending tool life in deep, narrow grooves. The integrated cooling and efficient chip evacuation reduce chatter and re-cutting, making it ideal for precision groove work in dies, molds, and precision machined components across automotive, aerospace, and mold-making applications. The Carmex Deep Groove Mill provides reliable performance and consistent results where depth, accuracy, and surface quality are crucial.
