The body accepts KSEM0688 inserts at insert seat size 1, allowing tip replacement without discarding the drill body. The straight-cylindrical shank measures 19.05 mm in diameter and 50.80 mm in length, and the overall length is 4.88 inches. Through-coolant delivery via a 3.50 mm coolant hole supports chip evacuation and heat management at the cutting zone. This tool is installed and operated by machinists and CNC tooling technicians on machining centers and drill presses requiring repeatable, tight-tolerance bore diameters.\u003c\/p\u003e\u003cp\u003eThis drill body is suited for production drilling in ferrous and non-ferrous materials where a depth-to-diameter ratio of 3xD is appropriate. Maximum drill depth reaches 52.39 mm, with a depth range of 40.00 mm to 60.00 mm. The replaceable-tip design is common in high-volume job shop and manufacturing environments where insert indexing reduces downtime compared to regrinding solid carbide drills. The straight-cylindrical shank interfaces directly with standard drill chucks, hydraulic chucks, and shrink-fit toolholders sized for 19.05 mm shanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccepts KSEM0688 replaceable inserts at seat size 1 for fast tip changes without body replacement\u003c\/li\u003e\n\u003cli\u003eThrough-coolant delivery via 3.50 mm internal coolant hole for chip flushing and thermal control\u003c\/li\u003e\n\u003cli\u003eDrill diameter range of 17.46 to 17.96 mm (0.6874 to 0.7071 inches decimal) for adjustable bore sizing\u003c\/li\u003e\n\u003cli\u003e3xD depth-to-diameter ratio with a maximum drill depth of 52.39 mm (2.06 inches)\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 19.05 mm diameter is compatible with standard CNC toolholding systems\u003c\/li\u003e\n\u003cli\u003eOverall length of 4.88 inches with a flute length of 2.72 inches for reach in typical machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with KSEM0688 insert style at insert seat size 1.

Ensure the toolholder bore is clean and free of debris before seating the shank, and verify insert seating and clamping torque per the toolholder manufacturer's specifications. Through-coolant connections must be confirmed leak-free before resuming cutting operations. Follow the machine tool manufacturer's guidelines for spindle speed and feed rate when using replaceable-tip drill bodies of this type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 17.46 mm (0.6874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 17.96 mm (0.7071 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 52.39 mm (2.06 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\u003eMaximum Drill Depth Range\u003c\/strong\u003e: 40.00 to 60.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.72 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: KSEM0688\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 1\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: 0.9921 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: 2238534\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744031867186,"sku":"2238534","price":519.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89f9ad4adc8d30691e4dd5b48e1436c6.jpg?v=1788853256","url":"https:\/\/voomisupply.com\/products\/kennametal-2238534-replaceable-tip-drill-ksem-series","provider":"Voomi Supply","version":"1.0","type":"link"}
