It accepts TGMF-style inserts secured by a clamp-style holding method and supports through-coolant delivery for improved chip evacuation and tool life at the cutting zone. With a maximum depth of cut of 0.43 inches and a groove width range of 0.157 to 0.197 inches, this toolholder handles internal grooving in bores down to 1.65 inches minimum diameter. The overall length is 8.65 inches with a 1-1\/4 inch shank, making it a direct-fit solution for standard turret and block-style tooling setups. Compatible insert size codes include TGMA, TGMF, and TGMF\/P.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for internal grooving applications across a universal range of workpiece materials, including steels, stainless steels, cast irons, non-ferrous metals, aluminum alloys, and heat-resistant superalloys, corresponding to ISO material groups H, K, M, N, P, and S. It is suited for production turning environments where tight groove tolerances and consistent insert indexing are required. The through-coolant capability makes it well-suited for deep-bore grooving where flood coolant cannot reach the cutting edge effectively. Setup is performed by a machinist or toolroom technician during turret configuration or job changeover.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand cutting direction for standard internal grooving on CNC turning equipment\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability improves chip flushing and extends insert life in deep-bore applications\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding provides repeatable seating for TGMF and TGMF\/P inserts\u003c\/li\u003e\n\u003cli\u003eMinimum bore entry of 1.65 inches supports a wide range of internal diameter applications\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for compatibility with CAM and presetter software\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across ISO groups H, K, M, N, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TGMF and TGMF\/P inserts, including complete insert compatibility with TGMF 4-series and TGMF 5-series.

Before mounting or indexing inserts, confirm that the machine spindle is fully stopped and the turret is locked in a safe position. Use the appropriate torque wrench and clamping screw per the toolholder manufacturer guidelines when securing the insert. Verify through-coolant port alignment with the machine turret coolant supply before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: TGI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Type\u003c\/strong\u003e: Non-Face Grooving, Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Groove Width\u003c\/strong\u003e: 0.157 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Groove Width\u003c\/strong\u003e: 0.197 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 6.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 2.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 1.00 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TGMF, TGMF\/P, TGMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Insert Compatibility\u003c\/strong\u003e: TGMF 4-series, TGMF 5-series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\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: 2850060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730675171634,"sku":"2850060","price":682.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/684702df7e43653faaee8466dac96e17.jpg?v=1788721288","url":"https:\/\/voomisupply.com\/products\/iscar-2850060-internal-grooving-toolholder-top-grip","provider":"Voomi Supply","version":"1.0","type":"link"}
