It carries the GTR3W-8D insert designation, manufactured from solid carbide with an IC354 PVD-coated grade suited for consistent performance in grooving applications. The insert delivers a 3.1 mm (0.122 inch) cutting width with an 8-degree right-hand lead angle, a 7-degree relief angle, and a 0.20 mm corner radius. The W-style chipbreaker promotes chip control during grooving cuts. Licensed machinists and CNC operators working in production and job-shop environments are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is applied in cutoff and grooving operations on ferrous and non-ferrous materials. The IC354 grade with PVD coating targets a C5-C6 material grade range, making it appropriate for steel and alloy turning applications. It is sized to fit insert seat size 3 toolholders configured for GTR-style inserts. The right-hand orientation determines toolholder compatibility and cutting direction. This insert is a single-use, single-end design and is not configured for reversal or repositioning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.1 mm (0.122 inch) cutting width for consistent groove and cutoff dimensions\u003c\/li\u003e\n  \u003cli\u003eIC354 PVD-coated solid carbide grade rated for C5-C6 material applications\u003c\/li\u003e\n  \u003cli\u003e8-degree right-hand lead angle with 7-degree relief angle for controlled entry geometry\u003c\/li\u003e\n  \u003cli\u003e0.20 mm corner radius minimizes stress concentration at groove base\u003c\/li\u003e\n  \u003cli\u003eW-style chipbreaker integrated into insert geometry for chip management\u003c\/li\u003e\n  \u003cli\u003eSingle-end design for dedicated toolholder seat size 3 systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit insert seat size 3 toolholders configured for GTR-style grooving and cutoff inserts with a right-hand orientation.

Disengage the machine spindle and confirm the turret or toolpost is fully stopped before handling inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket for wear or debris before seating a new insert to ensure proper support and geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC354\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: PVD Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.10 mm (0.122 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 8 degrees, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6099276\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748335649074,"sku":"6099276","price":254.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d10e3b50885a355fc6ad9f5d199f623_833d482d-5e68-4a8b-83ba-b54f99765d5e.jpg?v=1788892609","url":"https:\/\/voomisupply.com\/products\/iscar-6099276-cutoff-insert-gtr3w-8d-ic354-carbide-3-1mm","provider":"Voomi Supply","version":"1.0","type":"link"}
