Solid carbide (VHM) corner radius end mill Ø4 R-1 – precise radii in small molds
The Ø4 R-1 corner radius end mill is a specialized carbide tool for creating larger radii and transitions in steels hardened to up to 45 HRC. Four cutting edges with a TiAlN coating enable precise machining of pockets, slots, and contoured components requiring a corner radius of 1 mm in professional toolrooms.
Key advantages of the corner radius end mill Ø4 R-1 Z-4
- Solid cemented carbide (VHM) with TiAlN coating – hardness exceeding 60 HRC and resistance to temperatures above 800°C
- Corner radius R-1 mm – creates larger radii and smooth transitions in small die and mold components
- Compact diameter of 4 mm – access to narrow spaces and hard-to-reach areas while maintaining a larger radius
- Four carbide cutting edges – evenly distributed cutting forces ensure stability at high spindle speeds
- Machining steels up to 45 HRC – suitable for tool steels, hardened steels, and structural steels
This tool is used for producing small injection molds, finishing pockets in dies, and machining components requiring larger radii in confined spaces. The TiAlN coating doubles tool life compared with uncoated end mills. Increase machining precision – order now and achieve excellent finishes.

Frequently asked questions
An end mill with an R-1 mm radius creates radii and transitions that are twice as large, making it suitable for components requiring gentler curves. The choice depends on the mold design and required corner dimensions.
The TiAlN coating doubles tool life compared with the standard version. In hardened steels, 15-25 hours of machining can be achieved with appropriate cutting parameters.
The solid carbide (VHM) tool performs very well with aluminum and copper alloys. Spindle speed and feed must be adjusted to the characteristics of the soft material.
