The body accepts two indexable inserts compatible with the HPMT156812-GP insert style, allowing fast insert changes without removing the drill from the machine. With a nominal drill diameter of 2.125 inches and a maximum drill depth of 6.375 inches, this tool delivers a 3xD depth-to-diameter ratio suited to rigid setups in CNC machining centers and manual boring mills. Coolant-through capability is supported via a 1\/4-inch threaded coolant port at the shank end, helping flush chips and extend insert life during deep-hole cycles. Tool body material is steel.\u003c\/p\u003e\n\u003cp\u003eThis drill is intended for use in metalworking environments where large-diameter holes are required in a single operation without pre-drilling. Typical applications include job shops, OEM manufacturing floors, and maintenance departments working with structural steel, cast iron, and similar machinable metals. The 1.5-inch straight cylindrical shank fits standard ER and hydraulic chuck toolholders in that bore range, making setup straightforward on most CNC turning or machining center spindles. Right-hand cutting direction is standard. Installation and operation should be performed by qualified machinists following shop safety and machine guarding procedures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.125-inch nominal drill diameter with maximum drill diameter of 2.189 inches\u003c\/li\u003e\n  \u003cli\u003e6.375-inch maximum drill depth at a 3xD depth-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eAccepts 2 indexable inserts compatible with HPMT156812-GP insert style\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with 1\/4-inch threaded shank-end coolant port\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with straight cylindrical shank for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eSteel tool body construction for rigidity under high feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with HID drill style toolholders.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body. Confirm the toolholder bore matches the 1.5-inch shank diameter and that set screws or clamping mechanisms achieve adequate holding force for the feed rates intended. Verify coolant port connection at the shank end before initiating a coolant-through cycle to prevent uncooled dry running.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter (Nominal)\u003c\/strong\u003e: 2.125 inches (53.98 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 2.189 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 6.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3.0 inches (76.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.572 inches (166.93 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 1.949 inches (49.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: HPMT156812-GP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Drill Style\u003c\/strong\u003e: HID\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank End Coolant Hole Thread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 11.5 inches L x 2.75 inches W x 2.75 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4006144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739953365298,"sku":"4006144","price":1213.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dffaacedc65291d3a088854d2725d9c9.jpg?v=1788820697","url":"https:\/\/voomisupply.com\/products\/hertel-4006144-indexable-insert-drill-2-1-8-in-3xd","provider":"Voomi Supply","version":"1.0","type":"link"}
