Built to the E-STLP toolholder style, it accepts TP.. series inserts secured by a screw-clamp holding method. The bar features a minimum bore diameter of 15.24mm (0.600 inches) and an overall length of 203.20mm (8.000 inches), with a 12.70mm (0.500 inch) shank diameter. A neutral rake angle and a -5 degree lead angle provide stable, controlled cutting geometry. Through-coolant capability supports chip evacuation and heat management in deep-bore applications. This tool is intended for installation and use by machinists and CNC toolroom professionals.\u003c\/p\u003e\u003cp\u003eThe 1152770 is suited for internal boring operations on CNC lathes and turning centers where left-hand tooling orientation is required. The through-coolant design makes it well-suited for deeper bore applications where direct coolant delivery to the cutting zone is critical for tool life and surface finish. The screw-clamp insert retention provides repeatable indexing, reducing setup time between insert changes. Typical applications include finishing and semi-finishing of bored holes in ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand E-STLP toolholder style for correct cutting orientation on CNC turning setups\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-bore applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability with a 0.187-inch coolant hole diameter for direct cutting-zone delivery\u003c\/li\u003e\n\u003cli\u003eAccepts TP.. series inserts with 1\/4-inch inscribed circle and 3\/32-inch insert thickness\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method ensures secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eNeutral rake (0 degrees) with -5 degree lead angle for controlled chip formation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TP.. series indexable inserts.

Ensure the machine spindle is fully stopped and the turret is in a safe, indexed position before mounting or removing the tool. Confirm shank clamping torque meets the machine tool manufacturer's specifications for the turret style in use. Connect through-coolant supply only after confirming port alignment and adequate coolant pressure for the application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: E-STLP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 15.24mm (0.600 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.70mm (0.500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 203.20mm (8.000 inches)\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: TP..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch\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: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.312 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: 0.187 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.661 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: 1152770\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51999803375922,"sku":"1152770","price":871.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ff69e425a7d5d59a993186b76231dbf.jpg?v=1789995888","url":"https:\/\/voomisupply.com\/products\/kennametal-1152770-indexable-boring-bar-e-stlp-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
