KTMS T-Slot Cutters

Designed to offer high metal-removal rates while minimizing the cost per cutting edge, Kennametal’s KTMS T-Slot cutters excel in producing precise "T" slots in machine beds with small radial depths of cut. These slot cutters are a versatile solution for T-slotting and side milling operations on cast iron and steel. The SDMT-EGG inserts engineered for KTMS cutters feature four honed cutting edges, providing exceptional durability and precision. To achieve optimal performance, it is recommended to maintain cutting feed rates between 0.10 to 0.15mm per revolution, as lower rates may lead to undesirable vibrations.
