DLC Coated 2 Flute Solid Carbide Ball Nose End Mill for Aluminium – Standard Length
The Stiger DLC coated 2 flute ball nose end mill is a solid carbide cutter for high-performance 3D machining in aluminium. DLC (Diamond-Like Carbon) is a very hard, very slippery coating with an extremely low friction coefficient. Aluminium chips slide off the flutes instead of welding to the cutting edge. That stops built-up edge, which is the main cause of poor finish, inaccurate profiles and broken tools in aluminium.
The full-radius ball end produces smooth, accurate curved surfaces, and two open flutes clear chips fast at high spindle speeds. The standard length keeps the tool short and rigid for maximum accuracy and the best possible finish. Use it for 3D profiling, contouring, cavity work, fillets and radiused grooves on CNC machining centres and routers.
Features
- DLC (Diamond-Like Carbon) coating – very hard, ultra-smooth surface with extremely low friction
- Prevents built-up edge – aluminium won’t stick to or weld onto the cutting edge
- Bright, smooth 3D finish – reduces or eliminates hand polishing and secondary finishing
- 2 flute geometry – large chip space for fast chip evacuation at high speeds and feeds
- Full ball nose radius (R = D ÷ 2) – smooth blending on curved and sculptured surfaces
- Standard length – maximum rigidity for accuracy and finish
- Sizes – R0.5 to R6 (Ø1 mm to Ø12 mm)
- Plain cylindrical shank – suits collet, shrink-fit and hydraulic holders
Applications
Aluminium and aluminium alloys, as well as copper, brass, bronze, plastics, acrylic and composites. Ideal for aluminium moulds and tooling, aerospace and automotive components, prototyping, 3D surfacing, fillets and radiused edges.
