It carries a KC7315 fine grain solid carbide tip with a PVD-applied TiAlN coating and an HPG insert geometry. The drill features a 140-degree point angle, two helical flutes, and through-coolant capability including support for minimum quantity lubrication (MQL). The cutting diameter measures 1.5142 inches (38.00mm) with a flute length of 19.00mm and an overall projection of 1.0230 inches. It is installed and serviced by machinists and tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis replaceable tip drill is suited for general drilling operations on steel and cast iron workpieces in both production machining and maintenance environments. The KSEM platform is built for use in CNC machining centers and milling machines where controlled tool runout and consistent hole quality are required. Documented application support includes inclined exit drilling, stacked plate drilling, and standard through-hole drilling with or without through-coolant. The clamp-style insert holding method ensures secure tip retention under aggressive feed conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KC7315 fine grain tip with PVD TiAlN coating for wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry with 140-degree drill point angle for controlled entry and exit\u003c\/li\u003e\n\u003cli\u003eTwo helical flutes with 2-margin design for stable cutting and chip evacuation\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capable, compatible with both flood coolant and MQL systems\u003c\/li\u003e\n\u003cli\u003eClamp-style insert retention for repeatable tip indexing and positioning\u003c\/li\u003e\n\u003cli\u003eSupports inclined exit and stacked plate drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replaceable tip for use in KSEM-series drill bodies accepting insert seat size 10.
