Manufactured under the KCP15A grade with a fine-grain carbide substrate, this insert features an AlTiN (aluminum titanium nitride) coating applied via PVD process for improved heat and wear resistance. The HPG insert geometry and 180-degree drill point angle are engineered to deliver clean entry and exit in demanding ferrous materials. It is installed and serviced by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip insert is intended for drilling operations in steel and cast iron workpieces, covering ISO material groups P and K. The KTFSS series system is suited for applications including standard drilling, inclined surface entry and exit, and stacked-plate drilling. With a 2-flute, 2-margin, helical flute configuration and regular spiral type, it provides stable chip evacuation and consistent hole quality. Coolant-through capability is not included in this design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide KCP15A fine-grain substrate for hardness and toughness in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating via PVD process for extended tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eHPG insert geometry with 180-degree included angle for accurate drill point positioning\u003c\/li\u003e\n  \u003cli\u003e2-flute, 2-margin helical flute design supports stable chip control\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding in ZA seat size for positive, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eRated for inclined exit, stacked-plate, and standard drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KTFSS-series replaceable tip drill bodies accepting a ZA insert seat, with ISO designation KTFSS08750HPG.
