The Carmex Chamfering End Mill is a precision 90\u00b0 countersink designed for clean, dependable chamfers and deburrs across a range of materials. Built from solid carbide and finished with a high-performance coating, it delivers accurate edges for both production runs and detailed repairs.

• Diameter: 3 mm
• Angle: 90\u00b0 chamfer/countersink geometry for precise edge finishing
• Material: Solid carbide with CR3 ultra-fine grade for high hardness and wear resistance
• Coating / Grade: PVD coating on CR3 for enhanced heat resistance and edge retention
• Alternative Grade: K20 uncoated sub-micron carbide grade, optimized for aluminum and non-ferrous materials, stainless steels, and titanium
• Applications: Specifically designed for chamfering and countersinking in a single operation to improve finish consistency

This end mill helps you achieve crisp, uniform chamfers and countersinks with minimal burrs, improving both the appearance and function of machined parts. The CR3 ultra-fine carbide grade provides outstanding hardness and edge stability under demanding cutting conditions, while the PVD coating enhances tool life and performance at higher speeds. The 3 mm diameter is particularly well-suited for small-part machining, electronics housings, and precision assemblies where clean edges and repeatable results matter.
