The Carmex Carbide Groove Mill with Internal Coolant is a precision cutting tool designed for internal and external grooving across a variety of materials. Constructed from solid carbide and featuring an integrated internal coolant, it delivers consistent performance and extended tool life in demanding machining conditions.

• Material: Solid carbide construction for rigidity, durability, and long tool life.
• Internal coolant: Coolant channels through the flutes to improve chip evacuation and temperature control.
• Groove geometry: Precisely engineered grooves for clean, accurate grooving and the ability to create intricate profiles.
• Internal and external grooving: Versatile tool designed to handle both internal and external grooving with the same holder.
• Grooving diameter support: Capable of grooving diameters as small as 4 mm for tight, detailed features.
• Flute configuration: 3–5 spiral flutes that provide efficient cutting and effective chip removal.
• Size: 9.8 mm x 1.20 mm

The internal coolant through the flutes helps maintain stable grades of material removal and reduces heat buildup, which translates to longer tool life and more consistent finishes. The tool’s single-function capability for both internal and external grooving simplifies setup and inventory, while the precise groove geometry supports clean edges and accurate profiles in challenging materials. Ideal for prototyping, small-batch runs, and production environments where reliable grooving performance matters.
