SDM chipbreaker – Machine Part – AH6225
IMPROVED TOOL LIFE & PRODUCTIVITY
SDM is a new chipbreaker with a cutting edge that features unique variable T-land widths and large rake angle. This dramatically impeded notch wear development. As the result, per-edge tool life was 1.5 times longer even the feed rate was 1.5 times higher compared to the competitor’s tool.
