Part of the KSEM series, it accepts KSEM0938 inserts at an insert seat size 4, allowing tip replacement without discarding the drill body. The shank diameter measures 25.4 mm (approximately 1 inch) with a Weldon flat profile for secure toolholder engagement. Overall length is 244.48 mm (9.625 inches), with a flute length of 148.59 mm (5.85 inches). Through-coolant capability is supported via NPT-threaded coolant ports, making it suitable for high-speed, high-feed drilling where heat and chip evacuation are critical concerns. Machinists and tool-room professionals install this drill on CNC machining centers and turning centers.\u003c\/p\u003e\u003cp\u003eThis drill covers a diameter range of 23.81 to 24 mm (0.9374 to 0.9449 inches) and achieves a maximum drill depth of 120 mm (4.72 inches), representing a 5xD depth-to-diameter ratio. It is suited for production drilling operations in steel, cast iron, and similar ferrous materials where consistent bore diameter and repeatable positioning are required. The Weldon flat shank mates with standard Weldon-style toolholders commonly found in CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplaceable KSEM0938 insert tip eliminates full tool replacement at end of tip life\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with NPT ports: 1\/8-27 body side and 1\/4-18 shank end\u003c\/li\u003e\n\u003cli\u003e5xD depth-to-diameter ratio supports deep-hole drilling up to 120 mm\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive drive and prevents rotation in the holder\u003c\/li\u003e\n\u003cli\u003eInsert seat size 4 for repeatable tip indexing and diameter accuracy\u003c\/li\u003e\n\u003cli\u003eKSEM series platform allows one body to run multiple compatible insert geometries\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM0938 series replaceable tips at insert seat size 4.

Ensure the machine spindle is fully stopped and locked out before changing inserts or mounting the drill body. Secure the Weldon flat shank in a properly sized toolholder and torque the set screw per the toolholder manufacturer specifications. Confirm through-coolant connections are clear and leak-free before initiating a cut, and verify drill depth and diameter offsets in the machine controller before the first pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 23.81 mm (0.9374 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 24 mm (0.9449 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 120 mm (4.72 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 244.48 mm (9.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 148.59 mm (5.85 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: 25.4 mm (1 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0938\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\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: 2.78 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: 1505183\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747633824050,"sku":"1505183","price":736.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e5aab93f4aaa3b58a3669b58b4fa746.jpg?v=1788883828","url":"https:\/\/voomisupply.com\/products\/kennametal-1505183-replaceable-tip-drill-weldon-flat","provider":"Voomi Supply","version":"1.0","type":"link"}
