It accepts KSEM0875 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 22.23 to 22.73 mm (0.8752 to 0.8949 inches) with a maximum drill depth of 66.68 mm (2.63 inches), reflecting a 3xD depth-to-diameter ratio. A straight-cylindrical shank measuring 25.4 mm in diameter and 76.20 mm in length provides secure clamping in standard toolholders. Through-coolant delivery via a 3.50 mm coolant hole supports chip evacuation and tool life in demanding cutting conditions.\u003c\/p\u003e\u003cp\u003eThis drill body is suited for production machining environments where consistent bore quality and repeatable tool changes are required. Typical applications include drilling structural steel, alloy steels, and cast materials on CNC machining centers and turning centers equipped with driven tooling. The replaceable-tip design reduces downtime compared to solid carbide drills, making it a practical choice for high-volume shops running medium-to-large bore diameters. The KSEM series is a common platform in job shops and production facilities that standardize on modular drilling tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccepts KSEM0875 replaceable insert tips at insert seat size 4 for fast tip changes without removing the body\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 3.50 mm coolant holes improves chip flushing and extends insert life\u003c\/li\u003e\n\u003cli\u003e3xD depth-to-diameter ratio with a maximum drill depth of 66.68 mm supports standard-depth production boring\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank (25.4 mm diameter, 76.20 mm length) fits common CNC toolholder styles\u003c\/li\u003e\n\u003cli\u003eOverall length of 6.63 inches (168.40 mm) provides adequate reach for most machining center setups\u003c\/li\u003e\n\u003cli\u003eFlute length of 3.47 inches supports chip clearance over the full drilling depth range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM0875 series replaceable drill tips at insert seat size 4, within the KENNAMETAL KSEM modular drilling platform. Compatible insert and seat sizing must match exactly to ensure proper tip retention and cutting geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with modular drill body systems. Ensure the machine spindle is fully stopped and the tool is de-energized before mounting or changing insert tips. The straight-cylindrical shank requires a properly sized and clean toolholder bore with adequate clamping force per the machine tool manufacturer specifications. Verify coolant supply ports are unobstructed and that through-coolant pressure is within the machine and toolholder rated range before starting a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 22.23 mm (0.8752 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 22.73 mm (0.8949 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 66.68 mm (2.63 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\u003eMaximum Drill Depth Range\u003c\/strong\u003e: 60.00 to 80.00 mm (2.50 to 3.50 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: 25.40 mm (1.00 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 76.20 mm (3.00 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.47 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0875\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 3.50 mm (0.1378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6755 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: 2238547\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740908486962,"sku":"2238547","price":631.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6509ea06ab5ce722e5cb6c9299682ed.jpg?v=1788828283","url":"https:\/\/voomisupply.com\/products\/kennametal-2238547-replaceable-tip-drill-ksem-series","provider":"Voomi Supply","version":"1.0","type":"link"}
