Advancements in substrate technology have l to the unfolding of three new cemented-carbide turning inserts from Toshiba Tungaloy America Inc., Itasca, Ill. The grades, TD905 TD915 and TD930 all benefit from disk-reinforced uniteed carbide (DRCC) technology, which, according to the company, improves insert hardness and toughness and boost succeeds feeds, and tooling life.

The technology concentrates upon the microstructure of the tungsten-carbide crystal. Toshiba Tungaloy researchers plant that they could preferentially increase the tungsten-carbide grains into a triangular,
