Dapra’s Edge2 spherical ballnose (SBN) system offers indexable finishing inserts featuring two usable cutting edges for cost effectiveness and high-quality finishes. According to the company, the thicker carbide construction provides better heat and stress absorption, and the resulting insert life enables longer unattended finishing runs with good surface finishes. The SBN series is also said to be ideal for tip cutting, 3D profiling, semi-finishing and light roughing. Solid carbide and carbide core cutter bodies are available, as are screw-on modular heads and modular extensions.

Fully through-hardened SBN cutter bodies provide optimum strength and longevity. High accuracy and centrality ensure minimal runout, and a close-tolerance insert pocket produced by EDM removes less body material for improved insert support.
