SX9Excellent notch and flank wear resistance when roughing gray cast iron｜Sialon ceramic

Ceramic grade with the best fracture resistance

Stable machining even in tough applications

Significantly improve productivity when replacing carbide tools with SX9

Features

  • The toughest ceramic grade
  • Excellent thermal shock and fracture resistance due to the needle-shaped particles formed during the ceramic manufacturing process

Competitor’s CVD coated carbide

300 pcs / corner
SX9 achieved stable machining results in this interrupted turning operation.
By replacing the CVD coated carbide with ceramic there was a significant reduction in cutting tool costs and an increase in production.
