Expanded Toroid Cutting Tool Line

Dapra Corporation has almost doubled their offering of toroid cutting tools by adding 12 shell mills in ODs from 2" through 8". For maximum versatility, four insert geometries--round, square, high feed and octagonal--are available for toroid cutters. The new octagonal inserts have eight-sided geometry for excellent general face milling capabilities, the company says. Their 45-degree lead angle provides increased feed capacity for face milling, profiling, helical interpolation and chamfering. In order to simplify the matching of the various-shaped inserts with specific cutter bodies, the company provides "R-value" designations, which can be found on each cutter body. The insert and cutter body R-values can be matched for compatibility.
