Description
The Carmex Carbide Groove Mill is a precision solid-carbide tool designed for CNC grooving tasks. Built for machinists and manufacturers, its full-radius profile and internal coolant deliver clean, accurate grooves with durable performance across metal and other hard materials.
- Diameter: 4 mm
- Radius: Full radius with an R0.5 mm corner
- Material: Solid carbide construction for exceptional hardness and wear resistance
- Coolant: Internal coolant channels for efficient cooling and chip evacuation
- Geometry: Precision grooving geometry with a smooth bottom profile for clean grooves
- Applications: Ideal for grooving, slotting, and creating precise grooves in metals and other hard materials
This combination translates to real-world benefits: reduced heat buildup, longer tool life, and consistent groove geometry across passes. The 4 mm diameter is well-suited for narrow slots and tight tolerances, while the 0.5 mm radius delivers clean, sharp corners and smooth transitions. Internal coolant helps evacuate chips and keeps workpieces cooler, minimizing the risk of surface damage and improving overall part quality.
