Built from solid carbide in IC908 grade and coated with TiAlN via a PVD process, this insert delivers consistent performance across a wide range of workpiece materials. The LG chipbreaker geometry promotes controlled chip evacuation during drilling operations. With an insert size code of 09, a width of 0.374 inches, and a length of 0.394 inches, this insert fits drill bodies engineered to ISCAR FINEBEAM series specifications. It is part of the ISO 13399 standard family, making tool data compatible with CAM and tool management systems.\u003c\/p\u003e\u003cp\u003eThis insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, P, and S. That range includes hardened steels, cast irons, general steels, stainless steels, and heat-resistant superalloys. It is suited for both production shop and job-shop environments where a single insert grade must handle varied material runs without frequent grade changes. Machinists and CNC operators in metal-cutting operations are the primary installers of this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 carbide grade with TiAlN PVD coating for broad material compatibility and wear resistance\u003c\/li\u003e\n\u003cli\u003eLG chipbreaker geometry for controlled chip formation and evacuation during drilling\u003c\/li\u003e\n\u003cli\u003eFINEBEAM series designation ensuring dimensional fit with compatible ISCAR drill bodies\u003c\/li\u003e\n\u003cli\u003eISO 13399 compliant — tool data integrates with CAM and digital tool management platforms\u003c\/li\u003e\n\u003cli\u003eUniversal material coverage across ISO groups H, K, M, P, and S\u003c\/li\u003e\n\u003cli\u003eCompact insert geometry: 0.374 inches wide by 0.394 inches long\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ISCAR FINEBEAM series indexable drill bodies that accept NPMT09 insert size inserts.

Always power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key as specified by the drill body — do not substitute drivers that may round the screw head. Inspect the pocket seating surface for chips or debris before installing a new insert to ensure full contact and repeatable runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NPMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: LG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: FINEBEAM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 09\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.374 inches (9.5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.394 inches (10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO groups H, K, M, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4818356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738457833778,"sku":"4818356","price":280.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7b0acfebc12e868d51b39d7217d82e4.jpg?v=1788799780","url":"https:\/\/voomisupply.com\/products\/iscar-4818356-npmt09lg-ic908-indexable-drill-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
