Solid carbide MD838 & MD839 Supreme Circle Segment Cutters perform finishing tasks up to 90% faster than traditional ball nose end mills

Waukesha, WI—Walter 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% 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. Tough and reliable machining is obtained even with long overhangs to attain high component precision. 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.
