Designed around the KSEM platform, this drill body accepts KSEM0563 insert tips at an Insert Seat Size B, allowing fast tip changes without removing the body from the spindle. The straight-cylindrical shank measures 19.05 mm in diameter and the tool reaches an overall length of 212.73 mm, with a maximum drill depth of 142.88 mm at a 10xD depth-to-diameter ratio. Drill diameter range is 14.29 to 14.5 mm (0.5626 to 0.5709 inches). This tool is intended for use by machinists and CNC operators in production environments.\u003c\/p\u003e\n\u003cp\u003eThe 1798244 is suited for high-production drilling applications in CNC machining centers and turning centers where repeatable hole geometry and fast insert indexing are priorities. The 10xD depth capability makes it appropriate for deep-hole applications in steel, cast iron, and similar machinable alloys. The straight-cylindrical shank interfaces directly with standard drill chucks, hydraulic chucks, and shrink-fit toolholders sized for a 19.05 mm bore. This drill body is used in aerospace, automotive, die-and-mold, and general metalworking shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccepts KSEM0563 replaceable insert tips at Insert Seat Size B for fast, on-machine tip changes\u003c\/li\u003e\n  \u003cli\u003e10xD depth-to-diameter ratio supports maximum drill depth of 142.88 mm\u003c\/li\u003e\n  \u003cli\u003eDrill diameter range of 14.29 to 14.5 mm covers a 0.5626 to 0.5709 inch bore window\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 19.05 mm diameter for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eFlute length of 158.93 mm provides adequate chip clearance throughout the full depth range\u003c\/li\u003e\n  \u003cli\u003eCoolant hole diameter of 2.50 mm supports through-spindle coolant delivery when the machine and toolholder support it\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM0563 series replaceable drill tip inserts at Insert Seat Size B within the KENNAMETAL KSEM drill body platform.

Confirm the toolholder bore matches the 19.05 mm shank diameter and that the toolholder is rated for the intended spindle speeds and feed rates. Seat the KSEM0563 insert tip fully before torquing the retention screw to the insert manufacturer specification. Inspect the insert seat and shank for chips, burrs, or coolant passage obstructions prior to each tool setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 14.29 mm (0.5626 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 14.50 mm (0.5709 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 142.88 mm (5.63 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 212.73 mm (8.3752 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 158.93 mm (6.2571 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: 19.05 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0563\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4938 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: 1798244\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750944801074,"sku":"1798244","price":738.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85b0042a936896c3e1fc9fa33beeb1b0.jpg?v=1788920744","url":"https:\/\/voomisupply.com\/products\/kennametal-1798244-replaceable-tip-drill-ksem-series","provider":"Voomi Supply","version":"1.0","type":"link"}
