The drill body accepts KSEM1000 insert tips at Insert Seat Size 5, allowing worn or damaged cutting tips to be swapped without replacing the entire tool. The straight-cylindrical shank measures 25.4 mm in diameter, and the overall length is 295.28 mm. Maximum drill depth reaches 182 mm, yielding a depth-to-diameter ratio of 7xD. Through-coolant delivery is supported via a 4 mm coolant hole diameter, helping to evacuate chips and control heat at the cutting zone. This tool is typically installed by CNC machinists and toolroom technicians on machining centers and CNC lathes configured for through-spindle coolant.\u003c\/p\u003e\u003cp\u003eThe 1519277 drill body covers a diameter range of 25.4 mm to 25.9 mm, accommodating different KSEM1000 tip sizes within that window. It is suited for production drilling in steel, cast iron, and similar materials where consistent hole quality and extended tool life are required. The 7xD depth capability makes it appropriate for deep-hole applications such as hydraulic manifolds, structural components, and mechanical housings where a single-pass approach is preferred over step drilling. The tool is part of the broader KSEM platform, which standardizes shank bodies and replaceable tips across a range of diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplaceable KSEM1000 insert tip system at Insert Seat Size 5 reduces tooling cost per hole\u003c\/li\u003e\n\u003cli\u003e7xD depth-to-diameter ratio supports drilling up to 182 mm deep in a single setup\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 4 mm coolant holes promotes chip evacuation and thermal control\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 25.4 mm shank for compatibility with standard ER and hydraulic toolholders\u003c\/li\u003e\n\u003cli\u003eFlute length of 215.06 mm provides adequate chip clearance through the full depth range\u003c\/li\u003e\n\u003cli\u003ePart of the standardized KSEM series platform for consistent insert and body interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM1000 series replaceable tips at Insert Seat Size 5.

Ensure the machine spindle and coolant supply are fully de-energized and locked out before mounting or removing the drill body. Confirm that the toolholder bore is clean and free of debris before inserting the shank, and verify through-coolant passages are clear and unobstructed before operation. Follow the machine tool manufacturer and KENNAMETAL application guidelines for feed rate and spindle speed selection appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 25.40 mm (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 25.90 mm (1.0197 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 182 mm (7.17 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth-to-Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 295.28 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 215.06 mm (8.4669 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 (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 76.20 mm (3.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 5\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 Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6645 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: 1519277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742389305650,"sku":"1519277","price":829.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35c8110a22dd463a1aa6476dd7fdec69.jpg?v=1788837145","url":"https:\/\/voomisupply.com\/products\/kennametal-1519277-replaceable-tip-drill-ksem-25-4mm","provider":"Voomi Supply","version":"1.0","type":"link"}
