With a drill diameter of 2.375 inches (60.33 mm) and a maximum drill depth of 7.125 inches, this tool follows a 3xD depth-to-diameter ratio. It accepts two indexable inserts compatible with the HPMT186812-GP insert style and incorporates through-coolant capability via a 1\/4-inch threaded coolant port at the shank end. Right-hand cutting direction and a 1.5-inch straight cylindrical shank make it suitable for use in CNC machining centers and large-capacity drill presses operated by machinist and tooling professionals.\u003c\/p\u003e\u003cp\u003eThis drill is suited for production environments where large-diameter holes are required in steel, cast iron, and similar materials. The through-coolant system supports extended tool life and chip evacuation during deep-hole operations. A flute length of 7.441 inches provides chip clearance across the full drilling depth. This tool is typically deployed in job shop and manufacturing settings where indexable tooling is preferred over solid carbide drills for cost-effective insert replacement rather than full tool regrind.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.375-inch drill diameter with a 2.446-inch maximum drill diameter at insert cutting edge\u003c\/li\u003e\n\u003cli\u003e3xD depth ratio with a maximum drill depth of 7.125 inches\u003c\/li\u003e\n\u003cli\u003eTakes two indexable inserts  -  compatible insert style: HPMT186812-GP\u003c\/li\u003e\n\u003cli\u003eCoolant-through design with 1\/4-inch threaded shank-end coolant port for chip evacuation and heat management\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 1.5 inches diameter and 3.0 inches shank length for secure machine-spindle retention\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; steel body construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with HPMT186812-GP indexable inserts.
