Description
The Helixor HX55 8mm 4 Flute R0.5 Corner Radius End Mill is a 4-flute solid carbide corner radius end mill engineered for steel and harder materials. The radiused corners add edge strength and reduce chipping compared with a sharp square end, giving excellent rigidity and longer tool life in high-speed CNC machining.
Why choose this corner radius end mill?
A sharp square corner is the weakest point of an end mill. A small corner radius spreads the cutting load, so the tool resists chipping, lasts longer and leaves a small fillet at the base of walls instead of a stress-raising sharp corner.
Recommended materials
- Hardened steels
- Alloy and carbon steels
- Stainless steels
- Cast iron
Typical applications
- Profiling and contouring
- Slotting
- Pocketing with a filleted floor
- General-purpose milling
