Description
The Carmex Chamfering End Mill is a precision 90° countersink tool designed for efficient, clean edge finishing in CNC milling. Built from solid carbide, it delivers reliable performance across a range of metals, making it ideal for machinists and shops that require consistent chamfers and countersinks in aluminum, stainless steel, titanium, and more.
- Diameter: 6 mm
- Chamfer angle: 90° countersink/chamfer geometry for accurate edge finishing
- Construction: Solid carbide body for rigidity, heat resistance, and long tool life
- Carbide grades: CR3 Ultra-Fine grade (high hardness and wear resistance) and K20 Sub-Micron grade (uncoated) for broad material compatibility
- Coating/Surface: PVD coating option to enhance wear resistance and maintain cutting performance
- Edge geometry: Sharp cutting edges and precise geometry to deliver clean, burr-free finishes
This end mill is designed to minimize finishing work by combining countersinking and chamfering in a single pass, reducing cycle times and improving part aesthetics. The CR3 grade ensures robust performance on tougher materials, while the K20 grade expands capability to aluminum and non-ferrous alloys, stainless steels, and titanium. The PVD coating adds an extra layer of protection for high-speed cutting, helping to maintain sharpness and extend tool life. Whether you're building housings, brackets, or precision-machined components, this 6 mm chamfering end mill delivers reliable, repeatable results that you can trust on every job.
