Built on the KSEM platform, the drill accepts KSEM0938 inserts at an insert seat size 4, allowing quick tip changes without removing the body from the machine. The Weldon Flat shank measures 25.4 mm in diameter and provides positive rotational drive in compatible chucks and holders. Through-coolant delivery is supported via both body-side and shank-end coolant ports, keeping cutting zones clear during aggressive feed cycles. Licensed machinists and tooling technicians working in production or job-shop environments typically install and service this tool.\u003c\/p\u003e\n\u003cp\u003eThis drill body is suited for ferrous and non-ferrous material removal in CNC machining centers and drill presses where deep-hole performance at an 8xD depth-to-diameter ratio is required. The maximum drill depth reaches 190.5 mm, making it appropriate for through-holes and blind bores in medium-to-heavy workpieces. The tool is well matched to applications in automotive, aerospace, and general metalworking where repeatable hole geometry and fast insert indexing reduce downtime on high-volume runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable-tip design accepts KSEM0938 inserts at insert seat size 4 for fast, on-machine tip changes\u003c\/li\u003e\n  \u003cli\u003e8xD depth-to-diameter ratio supports maximum drill depth of 190.5 mm\u003c\/li\u003e\n  \u003cli\u003eWeldon Flat shank at 25.4 mm diameter provides positive rotational drive and secure chuck engagement\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability with body-side 1\/8-27 NPT and shank-end 1\/4-18 NPT coolant ports\u003c\/li\u003e\n  \u003cli\u003eOverall length of 307.98 mm with a flute length of 216.06 mm for extended reach in deep-bore setups\u003c\/li\u003e\n  \u003cli\u003ePart of the KSEM series, enabling insert commonality across multiple body sizes in a fleet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible insert style is KSEM0938 at insert seat size 4.

Torque the insert per the tooling manufacturer's documentation included with the insert, not from memory. Verify coolant port connections are clear and sealed before resuming operation. Confirm the holder bore matches the 25.4 mm Weldon Flat shank specification before mounting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 23.81 mm (0.9374 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 24 mm (0.9449 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 190.5 mm (7.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth-to-Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 307.98 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 216.06 mm (8.5063 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: 25.4 mm (1 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0938\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\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\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.94 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: 1517235\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":67637873475890,"sku":"1517235","price":917.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2bf5f2ea8d230572930363cc81cdc0f_aa629fef-fafe-46e5-bc71-ffe1c6ee98c0.jpg?v=1790452931","url":"https:\/\/voomisupply.com\/products\/kennametal-1517235-replaceable-tip-drill-23-81-24mm","provider":"Voomi Supply","version":"1.0","type":"link"}
