Dapra Corp. has introduced HFDEH high-feed inserts, which fit current Toroid cutter bodies. Part of Dapra's RHINO-CARB line of inserts, these new inserts are CNC-pressed, rather than ground. Because they are thicker, they are also stronger and have enhanced heat-absorption capabilities.

The HFDEH Inserts are designed for very aggressive metal cutting and long tool life, providing high metal-removal rates at lighter depths of cut. Their high-positive cutting edge is ideal for stainless steels, high-temperature alloys and gummy materials. The stronger edge of the HFDEH series allows for heavier chiploads, greater shock absorption and longer tool life. A positive top rake reduces cutting forces and lowers torque.

Dapra offers these inserts in the three tougher Toroid substrates: DMK30, DMK25, and DMP25. Suitable for 1-¼" diameters and above, the HFDEH high-feed inserts are ideal for such demanding applications as mold cavity and core roughing; roughing of complex part contours; pocketing; helical interpolation; and the roughing portion of the facemilling process.
