Built on the L-SCLP toolholder style, it accepts CP-style inserts secured by screw clamping, providing rigid, repeatable insert positioning. The shank measures 5\/8 inches in diameter with an overall length of 7.992 inches. A minimum bore diameter of 0.77 inches and a maximum bore depth of 1.03 inches define its working envelope. Internal coolant delivery through a 0.156-inch coolant hole helps evacuate chips and control heat in deep-bore applications. This bar is installed by machinists and tooling specialists in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for right-hand internal turning on lathes where tight bore tolerances and finish quality are required. The -5 degree lead angle and neutral rake geometry support consistent chip formation across a range of ferrous and non-ferrous workpiece materials. The heavy metal body provides significantly higher vibration damping compared to standard steel shanks, making it well-suited for longer reach boring where chatter is a concern. Typical applications include finishing and semi-finishing of bored holes in medium to high production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy metal body for superior vibration damping in long-reach boring\u003c\/li\u003e\n  \u003cli\u003eScrew clamp insert holding for secure, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with 0.156-inch coolant hole for in-cut chip evacuation\u003c\/li\u003e\n  \u003cli\u003eAccepts CP-style inserts with 1\/4-inch inscribed circle and 3\/32-inch thickness\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle and -5 degree lead angle for controlled chip geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation; center to cutting edge of 0.406 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept CP-style indexable inserts with a 1\/4-inch inscribed circle and 3\/32-inch insert thickness, consistent with L-SCLP toolholder system requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool builder guidelines for boring bar setup and overhang limits. Ensure the machine spindle and turret are fully powered down and locked out before mounting or removing the toolholder. Use calibrated torque tools when tightening the insert clamping screw to avoid insert seat damage. Verify bore alignment and runout with a dial indicator before taking the first cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.77 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.992 inches\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\u003eLead Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Neutral)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CP style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: L-SCLP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Heavy Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.28 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: 3331044\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731059802418,"sku":"3331044","price":754.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3afccec2819c983a8222d2f6e5662ab3.jpg?v=1788726398","url":"https:\/\/voomisupply.com\/products\/kennametal-3331044-indexable-boring-bar-5-8-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
