It accepts KSEM1109 insert tips at an Insert Seat Size 7, allowing fast tip changes without removing the body from the machine. The drill covers a diameter range of 28.17 to 28.67 mm (1.1091 to 1.2287 inches) with a maximum drill depth of 89.92 mm (3.54 inches), yielding a 3xD depth-to-diameter ratio. A Weldon Flat shank with a 31.75 mm diameter provides positive rotational drive in compatible tool holders. Through-coolant delivery is supported via NPT-threaded coolant ports, keeping cutting temperatures in check during deep-hole operations. Licensed machinists and CNC operators in production machining environments are the primary installers of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis drill body is part of the KENNAMETAL KSEM series, engineered for high-productivity drilling in steel, cast iron, and similar ferrous workpiece materials. It is suited for horizontal machining centers, vertical machining centers, and CNC lathes with live tooling where a Weldon Flat tool holder is available. The 89.92 mm maximum drill depth and 124.97 mm flute length make it well matched for through-hole and blind-hole applications in medium to large component machining, such as hydraulic manifolds, engine blocks, and structural weldments requiring consistent, repeatable bore quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable KSEM1109 insert tips — fast changeout without disturbing setup\u003c\/li\u003e\n  \u003cli\u003eDiameter range: 28.17 to 28.67 mm for size-adjustable fitment\u003c\/li\u003e\n  \u003cli\u003e3xD depth-to-diameter ratio — maximum depth 89.92 mm\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design with NPT ports (body side 1\/8-27 NPT, shank end 1\/4-18 NPT)\u003c\/li\u003e\n  \u003cli\u003eWeldon Flat shank, 31.75 mm diameter — positive anti-rotation drive\u003c\/li\u003e\n  \u003cli\u003eOverall length 228.6 mm (9 inches) with 124.97 mm flute length for chip clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM1109 replaceable insert tips, Insert Seat Size 7, within the KENNAMETAL KSEM series drill system.

Ensure the machine spindle is fully stopped and the CNC program is in a safe state before inserting or removing the drill body from the tool holder. Torque the Weldon Flat set screw according to your tool holder manufacturer specifications — no torque value is specified for this drill body. Verify through-coolant connections at both the body-side and shank-end NPT ports are clean and leak-free before running the spindle, and confirm insert tip seating before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 28.17 mm (1.1091 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 28.67 mm (1.1287 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 89.92 mm (3.54 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: 228.6 mm (9 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 124.97 mm (4.9201 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 31.75 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM1109\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Side Coolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank End Coolant Hole Thread Size\u003c\/strong\u003e: 1\/4-18 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.65 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291502\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1613657\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734612476210,"sku":"1613657","price":826.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5f658af0bffbc8a8a5121af45ea5cba_2cded1a3-3b10-4243-98b5-aed252d08088.jpg?v=1788763872","url":"https:\/\/voomisupply.com\/products\/kennametal-1613657-replaceable-tip-drill-28-17-28-67mm","provider":"Voomi Supply","version":"1.0","type":"link"}
