Built in the Heli-Grip series, it uses a clamp-style insert holding method compatible with GRIP-3 and HG.-3 insert size codes. The toolholder accepts groove widths from 0.118 inches to 0.125 inches and features a 0.75-inch by 0.75-inch square shank with a 5.5-inch overall length. It is rated for universal workpiece material compatibility, covering a broad range of ferrous and non-ferrous metals. Machinists and CNC tool-setup technicians rely on this holder for repeatable external grooving with quick insert indexing.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for external non-face grooving applications in production and job-shop turning environments. It handles right-hand cutting direction and is compatible with workpieces up to 1.76 inches in diameter. The 0.70-inch back-of-bar to cutting edge dimension and 1.43-inch head length support close-clearance grooving setups. Primary workpiece material codes H, K, M, N, P, and S confirm compatibility across cast iron, non-ferrous alloys, stainless steel, steel, and superalloys. The HELI toolholder style is consistent with ISCAR Heli-Grip system tooling used in standard lathe turrets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal, non-face grooving configuration with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eGroove width range of 0.118 to 0.125 inches for tight-tolerance grooving\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention compatible with GRIP-3 and HG.-3 insert size codes\u003c\/li\u003e\n  \u003cli\u003e0.75-inch by 0.75-inch square shank fits standard lathe turret pockets\u003c\/li\u003e\n  \u003cli\u003e5.5-inch overall length with a 4.07-inch shank length for extended reach setups\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for CAM and presetter integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with GRIP-3 and HG.-3 series ISCAR inserts.

Ensure the shank seating surface and turret pocket are clean and free of chips before clamping. Verify insert seating and clamp engagement before starting the spindle. Follow the machine tool manufacturer and ISCAR tooling guidelines for proper torque and setup procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Groove Width\u003c\/strong\u003e: 0.118 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Groove Width\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.70 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Workpiece Diameter\u003c\/strong\u003e: 1.76 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Type\u003c\/strong\u003e: Non-Face Grooving\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HELI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Heli-Grip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: GRIP-3; HG.-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H; K; M; N; P; S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\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: 0.79 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: 2500526\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727825830194,"sku":"2500526","price":252.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04262f69c933b3e7172a526c6bad2c03.jpg?v=1788683095","url":"https:\/\/voomisupply.com\/products\/iscar-2500526-indexable-grooving-toolholder-heli-grip","provider":"Voomi Supply","version":"1.0","type":"link"}
