It accepts KSEM0563 series inserts at an Insert Seat Size B, allowing the cutting tip to be swapped without replacing the entire drill body. The tool covers a diameter range of 14.3 to 14.5 mm (0.563 to 0.571 inches) and reaches a maximum drill depth of 71.44 mm (2.81 inches), representing a 5xD depth-to-diameter ratio. Through-coolant capability is standard, supplied via 1\/8-27 NPT ports at both the shank end and body side. Machinists and CNC operators in production shops install this tool in machining centers and turning centers where consistent, repeatable hole geometry is required.\u003c\/p\u003e\n\u003cp\u003eThis drill body is suited for medium-to-high production environments running ferrous and non-ferrous materials where replaceable-tip tooling reduces downtime versus brazed or solid carbide alternatives. The Weldon flat shank with a 19.05 mm (0.75 inch) shank diameter seats securely in standard Weldon-style tool holders, making setup straightforward on horizontal and vertical machining centers. The KSEM series platform is engineered for shops that prioritize insert-index speed and consistent cutting geometry across high-volume runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable-tip design accepts KSEM0563 inserts, Insert Seat Size B  -  no full-body replacement needed at tip wear\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant delivery via 1\/8-27 NPT ports at shank end and body side for effective chip evacuation and thermal control\u003c\/li\u003e\n  \u003cli\u003e5xD depth-to-diameter ratio with a maximum drill depth of 71.44 mm (2.81 inches)\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank at 19.05 mm diameter for positive anti-rotation engagement in Weldon-style holders\u003c\/li\u003e\n  \u003cli\u003eOverall length of 158.75 mm (6.25 inches) with a flute length of 84.10 mm (3.31 inches)\u003c\/li\u003e\n  \u003cli\u003eDiameter range of 14.3 to 14.5 mm accommodates minor diameter adjustment with compatible insert selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with KSEM0563 series replaceable-tip inserts at Insert Seat Size B within the KSEM tooling platform.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by CNC machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the drill body from the tool holder. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to prevent axial pull-out during cutting. Verify coolant line connections at the 1\/8-27 NPT ports are sealed and confirm through-coolant flow before initiating a cut cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 14.30 mm (0.563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 14.50 mm (0.571 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 71.44 mm (2.81 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: 158.75 mm (6.25 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 84.10 mm (3.31 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 (0.75 inches)\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 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: 0.7275 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: 1785289\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740241822002,"sku":"1785289","price":587.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/069c648d9fcfb291d4629aaade427fcb.jpg?v=1788823704","url":"https:\/\/voomisupply.com\/products\/kennametal-1785289-replaceable-tip-drill-14-3-14-5mm-weldon","provider":"Voomi Supply","version":"1.0","type":"link"}
