It accepts KSEM1313 insert tips at an insert seat size of 9, covering a drill diameter range of 33.35 to 34.35 mm (1.313 to 1.3524 inches). Maximum drill depth reaches 102.11 mm (4.02 inches), corresponding to a 3xD depth-to-diameter ratio. The shank is a 38.1 mm (1.5 inch) Weldon Flat design, providing positive rotational drive and reliable tool holding in standard Weldon-style chucks. Through-coolant capability is built in, directing coolant directly to the cutting zone to manage heat and chip evacuation during deep-hole drilling operations. Machinists and CNC operators in production and job-shop environments are the primary users of this tool body.\u003c\/p\u003e\n\u003cp\u003eThis drill body is suited for medium-to-large diameter hole-making in ferrous and non-ferrous materials on CNC machining centers and horizontal boring mills. The KSEM series platform allows the operator to replace worn insert tips without discarding the body, reducing tooling cost per hole in high-volume production runs. The 3xD depth rating covers the majority of through-hole and blind-hole applications in structural, automotive, energy, and general metalworking part families. Coolant is supplied both through the body side and the shank end, with NPT-threaded ports at both locations for easy hookup to machine coolant systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable-tip KSEM series platform accepts KSEM1313 insert tips, insert seat size 9\u003c\/li\u003e\n  \u003cli\u003eDrill diameter range: 33.35 to 34.35 mm (1.313 to 1.3524 inches)\u003c\/li\u003e\n  \u003cli\u003eMaximum drill depth: 102.11 mm (4.02 inches) at a 3xD depth-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eWeldon Flat shank, 38.1 mm diameter, resists rotational slip under heavy feed loads\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant construction with NPT-threaded body side port (1\/8-27) and shank end port (1\/4-18)\u003c\/li\u003e\n  \u003cli\u003eOverall length of 276.23 mm (10.875 inches) with a flute length of 157.99 mm (6.22 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM1313 replaceable drill tip inserts at insert seat size 9 within the KENNAMETAL KSEM series platform.

Ensure the machine spindle is fully stopped and the machine is locked out before loading or removing the tool body from the holder. Secure the Weldon Flat shank in a properly sized Weldon-style chuck or tool holder and confirm that set screws bear fully against the flat to prevent axial pullout under thrust loads. Verify coolant supply line connections at the appropriate NPT ports before initiating a cutting cycle, and confirm that insert tips are fully seated and clamped to the specified torque listed in the KENNAMETAL KSEM tooling documentation before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 33.35 mm (1.313 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 34.35 mm (1.3524 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 102.11 mm (4.02 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 276.23 mm (10.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 157.99 mm (6.22 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: 38.10 mm (1.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM1313\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 9\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\u003eBody Side Coolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank End Coolant Hole Thread Size\u003c\/strong\u003e: 1\/4-18 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.1447 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: 1616100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735304110386,"sku":"1616100","price":1007.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5f658af0bffbc8a8a5121af45ea5cba_3fd26531-c55c-475b-9dd4-1c5ccfd99d8b.jpg?v=1788771656","url":"https:\/\/voomisupply.com\/products\/kennametal-1616100-replaceable-tip-drill-weldon-flat-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
