It accepts KSEM2250 series insert tips at an Insert Seat Size 4, allowing the body to be reused while only the cutting tip is replaced. The drill covers a diameter range of 22.5 mm to 23 mm (0.8858 to 0.9055 inches) and reaches a maximum drilling depth of 72 mm (2.835 inches). Overall length is 161 mm (6.339 inches). Through-coolant delivery via a 3.5 mm (0.1378 inch) coolant hole keeps the cutting zone clear and extends insert life during deep-hole operations. This tool is installed by machining professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 1246034 is suited for drilling operations requiring a 3xD depth-to-diameter ratio in steel, cast iron, and similar workpiece materials. The 25 mm whistle notch shank provides positive, slip-resistant seating in compatible tool holders on CNC machining centers and turning centers. The 100 mm flute length and 56 mm shank length are optimized for chip evacuation at full depth. This body is part of the KSEM platform, which standardizes insert indexing across a range of drill diameters for shops running multiple hole sizes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiameter range: 22.5 mm to 23 mm to accommodate KSEM2250 insert tips\u003c\/li\u003e\n\u003cli\u003eMaximum drill depth of 72 mm with a 3xD depth-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 3.5 mm coolant bore for thermal management and chip flushing\u003c\/li\u003e\n\u003cli\u003e25 mm whistle notch shank for secure, positive location in the tool holder\u003c\/li\u003e\n\u003cli\u003eReplaceable-tip system reduces tooling cost by reusing the drill body\u003c\/li\u003e\n\u003cli\u003e100 mm flute length supports efficient chip evacuation at maximum depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM2250 series replaceable insert tips at Insert Seat Size 4, within the KENNAMETAL KSEM platform.

Power down and lock out the machine spindle before seating or replacing the insert tip. Ensure the whistle notch shank is fully engaged and properly torqued in the tool holder per the machine tool manufacturer specifications. Verify through-coolant supply lines are clear and coolant pressure is set per shop standards before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 22.5 mm (0.8858 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 23 mm (0.9055 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 72 mm (2.835 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\u003eOverall Length\u003c\/strong\u003e: 161 mm (6.339 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 100 mm (3.937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 56 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM2250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\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: 3.5 mm (0.1378 inches)\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: 0.882 pounds\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: 1246034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738954334514,"sku":"1246034","price":667.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78569aa43fc5288c9f691e6234614ad9.jpg?v=1788807234","url":"https:\/\/voomisupply.com\/products\/kennametal-1246034-replaceable-tip-drill-22-5-23mm","provider":"Voomi Supply","version":"1.0","type":"link"}
