The body accepts two SOMT-style inserts and delivers a maximum drill depth of 4.5 inches at a 3xD depth-to-diameter ratio. The cutting diameter reaches 1.65 inches, with a straight cylindrical shank measuring 1.5 inches in diameter. Internal coolant delivery is supported through 1\/16-27 NPT coolant-through ports, helping manage chip evacuation and heat during drilling cycles. This drill body is installed and serviced by machinists, CNC programmers, and tooling specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe ISCAR 3201851 is suited for general-purpose holemaking in ferrous and non-ferrous materials. It fits vertical machining centers, horizontal machining centers, and CNC lathes with live tooling capable of accepting a 1.5-inch straight shank. The 3xD ratio makes it appropriate for through-holes and moderate-depth blind holes in structural components, flanges, plates, and similar workpieces where consistent hole quality is required across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.65-inch maximum cutting diameter with a 3xD depth-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003eAccepts two SOMT-DT and SOMT-GF compatible indexable inserts\u003c\/li\u003e\n\u003cli\u003eCoolant-through design with 1\/16-27 NPT internal coolant ports for chip and heat management\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 1.5 inches diameter for broad machine compatibility\u003c\/li\u003e\n\u003cli\u003eBody length of 5.96 inches with a neck and collar diameter of 1.969 inches\u003c\/li\u003e\n\u003cli\u003eGeneral-purpose tool performance classification suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with SOMT-DT and SOMT-GF indexable insert styles in size code 120408-DT.
