[4] [5] DURO-Si DURO-SE DURO-SE H8606450 (DURO-Si) A8606450 (DURO-SE) Less wear, longer tool life – DURO-SE in a direct comparison Cylindrical end mill SX Ø10 mm HiPIMS precision – evident in coating structure and surface finish HPC partial cut in 1.4571 I Wear after 61 min operating time The following wear images show the direct comparison: At identical cutting data and the same operating time, tools with DURO-SE exhibit significantly lower and more uniform wear characteristics. The cutting edge stays intact longer – for measurably longer tool life and consistently high component quality. Wear Operating time Same wear DURO-SE can be used longer Same operating time DURO-SE has less wear Max. wear for FRAISA ReTool® High layer density The very dense layer structure makes it difficult for microcracks to propagate. The result is uniform, predictable wear and greater process reliability throughout the entire tool life. Extremely smooth surface The low-droplet coating surface reduces friction and heat generation. Material adhesion and built-up edges are effectively minimized – for clean surfaces and a stable cutting edge. DURO-SE technology – durable under thermal stress, stable at the cutting edge Thermally resilient DURO-SE is designed to withstand abrasive and thermal stresses. The coating withstands shortterm temperature peaks up to 1,100 °C (process-dependent) – a range where many coatings reach their limits. The substrate remains protected even under demanding conditions. DURO-SE is an optimized, AlTiSiN-based high-performance coating that combines three key properties. HiPIMS technology combines the advantages of arc and sputtering technologies. This produces a highly dense, uniform coating structure with an extremely smooth surface – reducing friction, minimizing material adhesion, and reliably protecting the cutting edge, even under high thermal loads. The result: maximum tool life, process reliability, and reproducible component quality.
