It accepts KSEM0500 style inserts in an Insert Seat Size C configuration, allowing tip replacement without removing the body from the machine. The drill covers a diameter range of 12.7 to 13.2 mm (0.5000 to 0.5197 inches) and reaches a maximum drilling depth of 63.5 mm (2.5 inches), representing a 5xD depth-to-diameter ratio. Through-coolant delivery is supported via 1\/8-27 NPT ports at both the shank end and body side, helping to control heat and clear chips at depth. The shank is a 19.05 mm Weldon Flat design, providing positive rotational drive in compatible toolholders. Overall length is 150.8 mm (5.937 inches). This body is installed and maintained by CNC machinists and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis drill body is suited for medium-diameter hole-making in steel, stainless, cast iron, and similar workpiece materials on CNC machining centers and turning centers equipped with live tooling. The 5xD depth ratio makes it appropriate for through-holes and blind holes in structural and component machining. The replaceable-tip design reduces tooling cost per hole by allowing insert indexing without disturbing the qualified shank setup. The Weldon Flat shank interfaces with standard ER or Weldon-style holders in the 19.05 mm size class. Through-coolant capability supports higher feed rates and extended insert life in interrupted or continuous cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable KSEM0500 insert tip  -  body is reusable, reducing per-hole tooling cost\u003c\/li\u003e\n  \u003cli\u003eDiameter range: 12.7 to 13.2 mm (0.500 to 0.5197 inches) with Seat Size C inserts\u003c\/li\u003e\n  \u003cli\u003e5xD depth-to-diameter ratio  -  maximum drill depth 63.5 mm (2.5 inches)\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design with 1\/8-27 NPT ports at shank end and body side\u003c\/li\u003e\n  \u003cli\u003e19.05 mm Weldon Flat shank for positive rotational engagement\u003c\/li\u003e\n  \u003cli\u003eOverall length 150.8 mm (5.937 inches); flute length 75.87 mm (2.987 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM0500 series replaceable drill tip inserts, Insert Seat Size C.

Confirm the machine spindle and toolholder are fully stopped and the control is in a safe state before mounting or removing the drill body. Torque the Weldon Flat set screw to the toolholder manufacturer's specification  -  do not rely on feel alone. When seating or replacing the KSEM insert tip, follow KENNAMETAL torque and seating procedures for the KSEM platform to ensure proper tip engagement before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 12.70 mm (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 13.20 mm (0.5197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 63.5 mm (2.5 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: 150.8 mm (5.937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 75.87 mm (2.987 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: 19.05 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0500\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\u003eCoolant Hole Thread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Side Coolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank End Coolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.706 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: 1785284\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741348299058,"sku":"1785284","price":592.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c235a3ed077a87bd0fa204a109c2ea5.jpg?v=1788830931","url":"https:\/\/voomisupply.com\/products\/kennametal-1785284-replaceable-tip-drill-ksem-series","provider":"Voomi Supply","version":"1.0","type":"link"}
