It accepts KSEM0906 insert tips and operates across a diameter range of 23.01 to 23.52 mm (0.9059 to 0.9260 inches), reaching a maximum drill depth of 69.06 mm (2.72 inches) at a 3xD depth-to-diameter ratio. The tool features a 25.4 mm straight-cylindrical shank and an overall length of 6.75 inches. Through-coolant capability is built in via a 3.50 mm coolant hole, supporting chip evacuation and thermal management at the cutting zone. Machinists and CNC operators in production and job-shop environments are the primary users of this tool body.\u003c\/p\u003e\u003cp\u003eThis drill body is suited for use in CNC machining centers and turning centers where consistent, repeatable hole diameters in the 23 mm range are required. The KSEM series platform is built around indexable replaceable tips, allowing the cutting edge to be swapped without removing the body from the spindle. This makes it a practical choice for high-volume drilling operations in steel, cast iron, and similar ferrous workpiece materials where tool change time and consistency are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiameter range: 23.01 to 23.52 mm (0.9059 to 0.9260 inches) using KSEM0906 insert tips\u003c\/li\u003e\n\u003cli\u003eMaximum drill depth of 69.06 mm (2.72 inches) with a 3xD drill-depth-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank, 25.4 mm diameter, 76.20 mm shank length\u003c\/li\u003e\n\u003cli\u003eThrough-coolant delivery via 3.50 mm coolant hole for chip control and heat reduction\u003c\/li\u003e\n\u003cli\u003eInsert seat size 4 for secure tip indexing and repeatable geometry\u003c\/li\u003e\n\u003cli\u003eOverall length of 6.75 inches with a flute length of 3.59 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with KSEM0906 replaceable-tip inserts, insert seat size 4.

The machine spindle should be powered down and locked out before mounting or removing the drill body from the tool holder. Confirm shank fit and clamping torque per machine tool manufacturer specifications before operation. Verify coolant-through passages are clear and coolant pressure is within machine specifications before beginning any drilling cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 23.01 mm (0.9059 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 23.52 mm (0.9260 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 69.06 mm (2.72 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 3xD\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: 25.40 mm (1.00 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 76.20 mm (3.00 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0906\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\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: 1.68 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291502\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: 2238550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741415866674,"sku":"2238550","price":657.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30ed7ba4b0f0830935eeb206e9f24be3_2f239b61-44a8-4c97-9d6d-7d9740746c2e.jpg?v=1788831386","url":"https:\/\/voomisupply.com\/products\/kennametal-2238550-replaceable-tip-drill-ksem-series","provider":"Voomi Supply","version":"1.0","type":"link"}
