AH9130, consisting of a PVD coating layer optimized for drilling applications with a dedicated carbide substrate, is the latest insert grade specifically developed to provide significant tool life improvements and more predictable wear patterns in hole making applications of ISO P (steel), ISO M (stainless steel), and ISO K (cast iron). 17 SMP-style inserts have been released in the latest grade, covering diameters from 20.0 mm to 35.0 mm (.787″ to 1.378″). In addition to Tungaloy’s versatile grade AH725 which covers most ISO materials, AH9130 provides DrillForce-Meister with added process security and tool life improvements in ISO P, M, and K applications.
