It covers a drill diameter range of 0.8126 to 0.8323 inches (20.64 to 21.14 mm) and achieves a maximum drill depth of 2.44 inches (61.91 mm), representing a 3xD depth-to-diameter ratio. The body features a straight-cylindrical shank measuring 1.0 inch (25.40 mm) in diameter and 3.0 inches (76.20 mm) in length. An integrated through-coolant system with 0.1378-inch (3.50 mm) coolant holes keeps cutting temperatures in check during extended production runs. This tool is installed and changed out by CNC machinists and tooling specialists in job shops, production machining cells, and manufacturing facilities.\u003c\/p\u003e\u003cp\u003eThe 2238544 body is used in CNC machining centers and drill presses where repeatable, close-tolerance bores are required. Its replaceable-tip design allows the cutting insert to be swapped at the machine without removing the body from the spindle, reducing downtime in high-volume production environments. The tool accepts KSEM0813 series inserts at an Insert Seat Size 3, making insert selection and ordering straightforward for shops already running the KSEM platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiameter range of 0.8126 to 0.8323 inches (20.64 to 21.14 mm) for flexible bore sizing\u003c\/li\u003e\n\u003cli\u003e3xD depth-to-diameter ratio with a maximum drill depth of 2.44 inches (61.91 mm)\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 0.1378-inch (3.50 mm) coolant holes for heat and chip management\u003c\/li\u003e\n\u003cli\u003eReplaceable-tip system accepts KSEM0813 inserts, Insert Seat Size 3\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 1.0 inch (25.40 mm) diameter for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eOverall length of 6.38 inches for reach in typical machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with KSEM0813 series replaceable drill tip inserts at Insert Seat Size 3.

Ensure the shank seating surface and spindle bore are clean and free of chips before mounting. Torque the replaceable tip insert according to the insert manufacturer documentation supplied with the KSEM0813 inserts. Verify coolant line connections are secure and that through-coolant flow is confirmed before initiating a cutting cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 0.8126 inches (20.64 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 0.8323 inches (21.14 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 2.44 inches (61.91 mm)\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\u003eOverall Length\u003c\/strong\u003e: 6.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.22 inches\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: 1.0 inch (25.40 mm)\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\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0813\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 0.1378 inches (3.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.0545 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291502\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2238544\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743077269810,"sku":"2238544","price":618.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a02d9de332184f20793170d4b5eaa13e.jpg?v=1788842309","url":"https:\/\/voomisupply.com\/products\/kennametal-2238544-replaceable-tip-drill-ksem-series-3xd","provider":"Voomi Supply","version":"1.0","type":"link"}
