Solid carbide (VHM) corner radius end mill Ø8 R 1 mm
Carbide end mill 8 R-1 Z-4 VHM 45 HRC is a corner radius end mill made of solid cemented carbide (VHM), designed for machining structural and alloy steels, austenitic stainless steels, and cast iron with a hardness of up to 45 HRC. The corner radius R 1 mm strengthens the cutting edge, lowers stress concentration, and reduces chipping in continuous and lightly interrupted cutting.
The diameter Ø8 combined with the corner radius geometry facilitates contour machining with a 1 mm radius transition and produces smooth pocket floors. The Z-4 configuration, with four effective cutting edges, distributes loads evenly and stabilizes the milling process. The end mill performs well in roughing and semi-finishing operations on CNC machining centers, ensuring predictable chip shape and controlled surface roughness.
Benefits
- Radius R 1 mm – strengthens the corner and reduces the risk of microcracking, maintaining stable cutting parameters for longer.
- Z-4 configuration – four cutting edges reduce end mill vibration and allow higher feed per tooth without compromising finish quality.
- Applications up to 45 HRC – effective machining of carbon steels, low-alloy steels, and austenitic stainless steels, as well as gray and ductile cast iron.
- Corner radius geometry Ø8 – makes it easier to maintain tolerances in narrow pockets and reduces steps in the radius-to-wall transition area.
The solid carbide (VHM) end mill Ø8 R-1 Z-4 45 HRC is recommended for profiling, contour machining, and finishing guide edges where process repeatability and consistent quality are essential.
