The drill accepts an HPG-geometry solid carbide insert tip with a TiAlN PVD coating, applied at the insert seat size 2 position. The 140-degree drill point angle reduces entry thrust and improves chip flow in through-hole and blind-hole applications. With coolant-through capability including MQL (Minimum Quantity Lubricant) support, this drill is suited for production environments where tool life and cycle time matter. It is installed by machinists and CNC operators in job shop and production floor settings.\u003c\/p\u003e\u003cp\u003eThis drill is engineered for drilling operations in steel (ISO P) and cast iron (ISO K) workpieces. Typical applications include standard through-hole drilling, inclined surface entry, stacked plate drilling, and through-coolant drilling cycles. The 2-flute, 2-margin helical flute design supports chip evacuation and hole finish consistency. The replaceable tip design allows the carbide insert to be swapped without removing the drill body from the spindle, reducing changeover time in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide HPG-geometry insert tip with TiAlN PVD coating for wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e140-degree included angle reduces entry thrust on flat and inclined surfaces\u003c\/li\u003e\n\u003cli\u003eCoolant-through channels support both flood coolant and MQL delivery\u003c\/li\u003e\n\u003cli\u003e2-flute, 2-margin helical flute design promotes chip evacuation and hole finish\u003c\/li\u003e\n\u003cli\u003eReplaceable tip system allows insert swap without removing the body from the spindle\u003c\/li\u003e\n\u003cli\u003eFine grain carbide substrate grade KC7315 for toughness and edge retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM series drill bodies accepting insert seat size 2 and HPG insert geometry.
