Due to their specially developed geometries, both milling cutters are ideal for final machining of components with steep walls, deep cavities, prismatic surfaces and transition radii. Click image to enlargeWalter has introduced two solid carbide circle segment milling cutters, the MD838 Supreme (conical) and the MD839 (tangential) Supreme.

They offer cost effective finishing because they are up to 90 per cent faster than finishing with ball nose end mills. This is primarily due to the new geometry of the milling cutters, featuring large radii in the cutting area and a higher number of teeth.

Higher productivity is gained not only due to the speed of these cutters, but also the greater number of teeth.

Due to their specially developed geometries, both milling cutters are ideal for final machining of components with steep walls, deep cavities, prismatic surfaces and transition radii. The cutters are ideal in the energy industry, die and moldmaking, medical technology manufacturing, and aerospace, as well as general metalworking. 

The MD838 Supreme (conical version) has an effective radius of 250-1000 mm, a corner radius of 0.5 - 4.0 mm and is available in diameters of 6-16 mm. Walter also offers a version of this tool with ConeFit ex-changeable head. The MD839 Supreme (tangential version) has an effective radius of 100 mm, a corner radius of 1-4 mm and in diameters of 6-16 mm. The two circle segment milling cutters are available both in the WJ30RD grade, for steel or cast iron materials, as well as in WJ30RA for ISO M and S.
