Built on the KSEM platform, this drill accepts KSEM0750 insert tips at an insert seat size 2, allowing the body to be reused while only the cutting tip is replaced. The straight-cylindrical shank measures 19.05 mm in diameter and 50.80 mm in length, with an overall length of 184.15 mm. Maximum drill depth reaches 100 mm, delivering a 5xD depth-to-diameter ratio. Through-coolant capability is built in, with coolant holes measuring 3.50 mm in diameter to support chip evacuation and tool life in demanding cuts.\u003c\/p\u003e\n\u003cp\u003eThis drill body is suited for production machining environments where consistent bore quality and reduced tooling cost per hole are priorities. Typical applications include CNC machining centers performing through-hole and blind-hole operations in steel, cast iron, and similar workpiece materials. The replaceable-tip design eliminates the need to regrind or replace the entire drill body, making it a practical choice for shops running medium-to-high volume part runs. The drill covers a diameter range of 19.05 mm to 19.55 mm, accommodating slight tip variations within the KSEM0750 insert family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKSEM platform accepts KSEM0750 replaceable insert tips at insert seat size 2\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design with 3.50 mm coolant holes for effective chip flushing\u003c\/li\u003e\n  \u003cli\u003e5xD depth-to-diameter ratio supports drill depths up to 100 mm\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank provides secure, concentric clamping in standard toolholders\u003c\/li\u003e\n  \u003cli\u003eFlute length of 129.33 mm allows full chip clearance through the cutting depth range\u003c\/li\u003e\n  \u003cli\u003eReusable body design reduces tooling cost compared to solid or brazed-tip drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with KSEM0750 series replaceable drill tips at insert seat size 2.

Confirm the toolholder bore matches the 19.05 mm straight-cylindrical shank before clamping. When replacing insert tips, follow the torque and seating procedure specified in the KENNAMETAL KSEM tooling documentation for seat size 2 inserts. Verify coolant passages are clear and that through-coolant pressure is within the range recommended by the machining center manufacturer before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 19.05 mm (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 19.55 mm (0.7697 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 100 mm (3.94 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 184.15 mm (7.25 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 129.33 mm (5.0917 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\u003eShank Length\u003c\/strong\u003e: 50.80 mm (2.00 inches)\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\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0750\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 2\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: 0.5913 pounds\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: 1329703\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742033445170,"sku":"1329703","price":660.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9eb8b9669fe4d56cab79d01db9dcb05.jpg?v=1788835050","url":"https:\/\/voomisupply.com\/products\/kennametal-1329703-replaceable-tip-drill-19-05mm","provider":"Voomi Supply","version":"1.0","type":"link"}
