It carries a Physical Vapor Deposition (PVD) applied AlTiN finish and is designed for use in KTFS-series replaceable tip drill bodies. The insert features an HPG geometry with a standard point type, 180-degree drill point angle, and a helical, regular-spiral flute profile with two flutes and two margins. It is installed by licensed machinists and tooling technicians working in precision metal-cutting environments.\u003c\/p\u003e\u003cp\u003eThis tip is suited for drilling applications in steel and cast iron workpieces, corresponding to ISO material codes P and K. Designed to handle inclined exit surfaces and stacked plate configurations, it fits production and job-shop environments where replaceable tip systems reduce downtime versus solid drill replacement. The HPG geometry and AlTiN finish together support performance in ferrous and wear-demanding materials without through-tool coolant, as this insert carries no coolant-through feature.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide fine grain construction in manufacturer grade KCP15A\u003c\/li\u003e\n\u003cli\u003eAlTiN coating applied via PVD process for surface hardness and heat resistance\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry optimized for steel and cast iron drilling\u003c\/li\u003e\n\u003cli\u003eTwo-flute, two-margin helical design with standard 180-degree point angle\u003c\/li\u003e\n\u003cli\u003eRated for inclined exit and stacked plate drilling applications\u003c\/li\u003e\n\u003cli\u003eInsert seat size K, compatible with KTFSS-series drill bodies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replaceable tip insert for KTFSS-series drill bodies accepting insert seat size K.
