New research from Tungaloy suggests that over 75 percent of the turning market takes cuts of 0.117" (3 mm) depth or less. Yet, the most common turning insert sold in North America is CNMG 432, capable of nearly 0.250" (6.35 mm) depth of cut. According to John Mitchell of Tungaloy Canada, author of a white paper on this topic, this discrepancy suggests that shops may be using inserts that are larger than necessary, resulting in waste.
Tungaloy’s solution is its EcoTurn series, a “downsized” version of its conventionally sized inserts. The EcoTurn inserts have the same thickness and chipbreaker geometry as the company’s regular inserts, but in a smaller, more affordable size. View the video above to learn more.
