Built from solid carbide, it accepts CP-style inserts secured by screw clamp holding and features through-coolant capability to manage heat and chip evacuation at the cutting zone. The bar carries a minimum bore diameter of 19.56 mm (0.770 inches), a 5\/8-inch shank diameter, and an overall length of 254 mm (10 inches). A neutral rake angle and a -5 degree lead angle define the cutting geometry. Machinists and toolroom professionals working on CNC lathes and boring mills are the primary users of this toolholder.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for internal diameter machining on CNC turning centers and horizontal boring mills where left-hand toolholder orientation is required. Its through-coolant design makes it appropriate for deep-bore applications and difficult-to-machine materials where heat buildup and chip packing are concerns. The screw-clamp insert holding method provides repeatable indexing without disturbing setup, making it a practical choice for production environments and tight-tolerance work. Insert geometry is controlled by the CP-style insert family with a 3\/8-inch inscribed circle and 5\/32-inch thickness.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand E-SCLP toolholder style for CNC turning and boring mill applications\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design with a 0.218-inch coolant hole diameter for effective heat and chip control\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-bore work\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding ensures secure, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eNeutral rake, -5 degree lead angle geometry compatible with CP-style inserts\u003c\/li\u003e\n  \u003cli\u003eCenter-to-cutting-edge distance of 0.406 inches for precise bore offset reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CP-style indexable inserts with a 3\/8-inch inscribed circle and 5\/32-inch thickness, as specified by the E-SCLP toolholder system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician with the machine powered off and all axes locked out per site lockout\/tagout procedures. Verify shank clamping torque against the machine tool manufacturer's specifications for 5\/8-inch boring bar holders before engaging the cut. Connect the through-coolant supply line according to the machine tool's internal coolant system requirements before initiating a cycle. Inspect insert seating and screw clamp engagement after each index to confirm cutting edge position.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 19.56 mm (0.770 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15.88 mm (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 254 mm (10 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-SCLP\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: CP style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral (0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.406 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: 0.218 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: 1152733\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731065962802,"sku":"1152733","price":1166.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f687cf98cf039fb6bf5a5004327d08d.jpg?v=1788726507","url":"https:\/\/voomisupply.com\/products\/kennametal-1152733-indexable-boring-bar-19-56mm-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
