Description
The Carmex Chamfering End Mill is a precision 90° countersink tool built for engineers and machinists who need clean, accurate edge finishing. Made from solid carbide and engineered for reliability, it delivers consistent chamfers across a variety of materials.
- Diameter: 8 mm cutting diameter for stable, predictable cuts.
- Angle: 90-degree chamfer/countersink geometry to produce precise edges every pass.
- Material: Solid CR3 Ultra-Fine carbide grade for high hardness, toughness, and wear resistance.
- Coating: K20 PVD coating to enhance heat tolerance and reduce friction during high-speed cutting.
- Compatibility: Effective on aluminium and non-ferrous alloys, as well as stainless steels and titanium with appropriate speeds and feeds.
- Cutting Edges & Geometry: Sharp, well-defined cutting edges and optimized geometry for clean, burr-free finishes.
This end mill is ideal for finishing operations that require a crisp countersink or chamfer with excellent edge quality. The combination of a robust carbide core and the K20 coating delivers dependable performance, longer tool life, and more consistent results in both small- and medium-scale machining projects. Use it to enhance screw-hole clearance, improve part aesthetics, and ensure professional, repeatable finishes on enclosures, housings, and precision components.
