Built on the KTFSS series platform, this drill features the KTFSS03438HPG tip insert in a KCP15A fine-grain carbide grade with a PVD-applied AlTiN coating. The cutting diameter is 0.3438 inches (11\/32 inches), and the 180-degree drill point angle supports standard entry and exit conditions. Two helical flutes with a regular spiral and a 2-margin configuration provide stable chip evacuation during drilling cycles. Licensed machinists, tool-and-die tradespeople, and CNC machine operators install and swap these tips as part of a modular tooling program.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill is suited for drilling steel and cast iron in both roughing and precision hole-making applications. The HPG insert geometry and G-series insert seat sizing are matched to the KTFSS body. The tip is secured by clamping, eliminating adhesive or interference-fit assembly. Supported applications include straight drilling, inclined exit drilling, and stacked-plate drilling operations, making this tip a practical choice for structural, fabrication, and machined-component work in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCP15A fine-grain solid carbide grade for wear resistance in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating applied via PVD process for heat and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003e180-degree included drill point angle for standard entry drilling\u003c\/li\u003e\n  \u003cli\u003eTwo helical flutes with 2-margin, no-coolant-through configuration\u003c\/li\u003e\n  \u003cli\u003eHPG insert geometry optimized for steel and cast iron chip formation\u003c\/li\u003e\n  \u003cli\u003eSupports inclined exit and stacked-plate drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replaceable tip insert for KTFSS-series modular drill bodies using G-series insert seat sizing.
