Built from solid carbide, this E-SDUP style toolholder accepts DP-series inserts secured by screw clamping and features a through-coolant channel to support high-speed, continuous cutting. The bar has a minimum bore diameter of 24.89mm (0.980 inches), a 3\/4-inch shank diameter, and an overall length of 254mm (10.0 inches). A neutral rake angle and a -3-degree lead angle make it well suited for stable finishing and semi-finishing passes in tight bores. Installation and setup are typically performed by machinists and CNC tooling technicians.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for internal boring applications where a left-hand cutting orientation is required. Through-coolant delivery directly to the cutting zone improves chip evacuation and extends insert life during deep-bore or high-feed operations. The 24.89mm minimum bore diameter and 0.562-inch center-to-cutting-edge measurement make this toolholder appropriate for small to mid-size bore work in steel, cast iron, and similar machinable alloys. It is a single-use configuration toolholder and is not designed as a multi-use or interchangeable modular system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand E-SDUP toolholder style for internal boring applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and vibration resistance in deep-bore conditions\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability with a 0.281-inch coolant hole diameter for direct chip and heat management\u003c\/li\u003e\n\u003cli\u003eAccepts DP-series indexable inserts with 3\/8-inch inscribed circle and 5\/32-inch insert thickness\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable positioning\u003c\/li\u003e\n\u003cli\u003eNeutral rake angle (0 degrees) and -3-degree lead angle for stable cutting geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DP-series (DP..) indexable inserts with a 3\/8-inch inscribed circle and 5\/32-inch thickness, as specified for the E-SDUP toolholder style.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the coolant supply is isolated before mounting or changing the toolholder or insert. The 3\/4-inch shank should be clamped in a compatible boring bar holder or turret pocket to the depth recommended by the machine manufacturer. Verify coolant line connection and insert seating before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 24.89mm (0.980 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 19.05mm (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 254mm (10.0 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: E-SDUP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DP.. series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.562 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: 0.281 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.14 pounds\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: 1152747\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737186795826,"sku":"1152747","price":1488.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eaa0fdb66fd3bc95620ba82185340ae7.jpg?v=1788785368","url":"https:\/\/voomisupply.com\/products\/kennametal-1152747-indexable-boring-bar-left-hand-e-sdup","provider":"Voomi Supply","version":"1.0","type":"link"}
