Wedges secure the cutting insert in the toolholder pocket, maintaining precise positioning under the cutting forces generated during internal diameter machining operations. This component is a consumable hardware item that wears or is lost during routine insert indexing. Machinists and tool crib technicians working with KENNAMETAL ATBI boring bar toolholders should keep replacement wedges on hand to minimize downtime during insert changes.\u003c\/p\u003e\n\u003cp\u003eThis wedge is intended for use in metal cutting environments where ATBI series boring bars are used for internal turning and boring operations. It is suited for both production shop and job shop settings running CNC turning centers or manual lathes equipped with compatible KENNAMETAL indexable boring bar toolholders. Replacement of worn or lost wedges restores proper insert clamping and helps maintain dimensional accuracy in bored features.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect replacement wedge for ATBI series indexable boring bar toolholders\u003c\/li\u003e\n  \u003cli\u003eCompatible with multiple ATBI toolholder sizes including ATBI-375-1 1\/2, ATBI-500-1 1\/2, ATBI-500-4, ATBI-625-4, ATBI-750-4, and ATBI-1000-4\u003c\/li\u003e\n  \u003cli\u003eSecures cutting insert in toolholder pocket to maintain positioning during machining\u003c\/li\u003e\n  \u003cli\u003eSold individually per package; minimum order quantity of 5 units\u003c\/li\u003e\n  \u003cli\u003eLightweight at approximately 1 pound per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL ATBI series indexable boring bar toolholders.

Ensure the boring bar is removed from the machine spindle or turret and all machine motion is stopped before servicing the toolholder. Use the appropriate Torx or hex key as specified by the toolholder design to seat the wedge and clamp the insert securely. Do not overtighten the clamping screw, as this can damage the wedge or insert seat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ATBI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Boring Bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Toolholder Styles\u003c\/strong\u003e: ATBI-1000-4, ATBI-375-1 1\/2, ATBI-500-1 1\/2, ATBI-500-4, ATBI-625-4, ATBI-750-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242100\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: 1256866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51783408615730,"sku":"1256866","price":153.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37308ce3216fcc854932b6531b710048.jpg?v=1789189421","url":"https:\/\/voomisupply.com\/products\/kennametal-1256866-indexable-boring-bar-wedge","provider":"Voomi Supply","version":"1.0","type":"link"}
