Reduce feed rate during ramping by 50%

Applications

This indexable insert is ideal for productive milling applications in the high feed range. Depending on the chosen grade (such as RT253, RT250X, RT305H, or RT820S), it covers a broad spectrum ranging from general steels and rust-proof stainless steels to demanding alloys. The different dimensions and geometries allow for exact adaptation to the respective workpiece contour.

Special features

The SDMT milling insert stands out with its robust basic shape, specifically engineered to safely absorb the immense cutting forces generated during high feed milling. Combined with the wear-resistant coatings of the carbide substrates, the system achieves high durability in continuous industrial use. To maintain consistent process stability, the feed rate during ramping must be reduced by 50%.
