The bar accepts WP-style inserts secured by a screw-clamp holding method and features a through-coolant channel with a 0.047-inch coolant hole diameter for effective chip evacuation and heat control at the cutting zone. With a minimum bore diameter of 8.15mm (0.3210 inches) and a neutral rake angle of 0 degrees, this tool is suited for precision finish and semi-finish boring passes where dimensional accuracy is critical. Licensed machinists and CNC operators install this tool in applications requiring tight bore tolerances in small-diameter features.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in production and job-shop environments for small-diameter internal boring on lathes and live-tool turning centers. The 1\/4-inch (6.35mm) round shank fits standard boring bar holders and quick-change tooling systems designed for that shank size. The -3-degree lead angle geometry influences cutting force direction and is appropriate for general-purpose boring where radial load management is a consideration. The 101.6mm (4.000-inch) overall length provides adequate reach for typical small-bore applications without excessive overhang. No multi-use tool designation applies; this bar is dedicated to boring operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-diameter bores\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability with 0.047-inch coolant hole for chip flushing and thermal management\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cut orientation for back-boring or specific spindle rotation requirements\u003c\/li\u003e\n  \u003cli\u003eNeutral rake (0 degrees) geometry compatible with a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e-3-degree lead angle for controlled radial cutting force distribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eAccepts WP-style inserts with a 3\/16-inch inscribed circle and 5\/64-inch thickness in the E-SWLP insert seat style.

Ensure the machine spindle is fully stopped and the tooling system is locked out before mounting or removing the boring bar. Torque the insert screw to the insert manufacturer specification using the correct Torx or hex key — do not over-torque. Verify coolant supply line pressure and flow compatibility with the machine tool before enabling through-coolant to avoid seal damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 8.15mm (0.3210 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.35mm (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 101.60mm (4.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: E-SWLP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WP style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral (0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.1560 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.1560 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: 0.0470 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1232 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: 1152753\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728732586290,"sku":"1152753","price":505.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/789770f2727bf0470ef2fdefbf5baea4.jpg?v=1788695577","url":"https:\/\/voomisupply.com\/products\/kennametal-1152753-indexable-boring-bar-e-swlp-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
