It accepts KSEM1900 series inserts at an insert seat size 2, allowing the cutting tip to be swapped without removing the drill body from the spindle. The shank is a 25 mm whistle notch design, and the tool delivers a maximum drill depth of 140 mm at a 7xD depth-to-diameter ratio. Through-coolant is supported via a 3.50 mm coolant hole, keeping the cutting zone clear of chips and controlling heat at depth. This tool is intended for use by machinists and tooling specialists in CNC machining centers and drill presses.\u003c\/p\u003e\u003cp\u003eThis drill body is suited for production drilling in ferrous and non-ferrous materials where consistent hole quality and fast insert indexing are required. The KSEM platform is designed for high-volume drilling operations in job shop and manufacturing environments. The 25 mm whistle notch shank provides positive drive and rotational security in compatible tool holders. The 224 mm overall length and 163 mm flute length accommodate setups requiring extended reach without sacrificing rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccepts KSEM1900 replaceable inserts at insert seat size 2 for fast tip changes without body removal\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability with 3.50 mm coolant hole diameter for chip evacuation at depth\u003c\/li\u003e\n\u003cli\u003e25 mm whistle notch shank for positive drive in compatible tool holders\u003c\/li\u003e\n\u003cli\u003e7xD depth-to-diameter ratio supports drilling up to 140 mm deep\u003c\/li\u003e\n\u003cli\u003e163 mm flute length and 224 mm overall length for extended-reach setups\u003c\/li\u003e\n\u003cli\u003ePart of the KSEM series platform for consistent tooling system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM1900 series replaceable inserts at insert seat size 2.

Verify spindle and tool holder compatibility with the 25 mm shank diameter before mounting. Confirm through-coolant passages are clear and coolant supply is connected before beginning any drilling cycle. Follow safe lockout and energy isolation procedures when changing inserts or setting tool offsets.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 19.00 mm (0.7480 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 19.50 mm (0.7677 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 140.00 mm\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: 224 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 163.00 mm (6.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 56.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM1900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 2\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: 3.50 mm (0.1378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.88 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: 1279864\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744014565682,"sku":"1279864","price":746.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10fa8abbd9bfd1669fcd6817de1514c0.jpg?v=1788852954","url":"https:\/\/voomisupply.com\/products\/kennametal-1279864-replaceable-tip-drill-19-19-5mm","provider":"Voomi Supply","version":"1.0","type":"link"}
