Built on the Heli-Grip platform with the HELII toolholder style, it accepts GRIP and GRIP Full Radius inserts held by a clamp-style insert holding method. The toolholder provides a maximum depth of cut of 0.197 inches and handles groove widths from 0.118 inches to 0.125 inches. Through-coolant capability supports chip evacuation and heat control at the cutting zone. With an overall length of 6.5 inches and a 0.75-inch shank diameter, this toolholder suits CNC turning centers and live-tool lathes where internal grooving is a routine operation.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for internal non-face grooving applications on both CNC turning centers and multi-axis lathes. The minimum hole diameter for entry is 0.986 inches, and the center-to-cutting-edge distance is 0.58 inches, making it suitable for tight-bore internal groove work. The universal material compatibility rating covers steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and titanium, corresponding to ISO material groups P, M, K, N, S, and H. This part is commonly specified by CNC machinists and tool-room technicians working in production or job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal right-hand cutting geometry with HELII toolholder style for secure insert seating\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.197 inches with groove width range from 0.118 inches to 0.125 inches\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs fluid directly to the cutting zone for improved tool life and chip control\u003c\/li\u003e\n  \u003cli\u003eAccepts GRIP and GRIP Full Radius indexable inserts via clamp holding method\u003c\/li\u003e\n  \u003cli\u003eMinimum entry bore diameter of 0.986 inches suits a wide range of internal bore sizes\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GRIP and GRIP Full Radius series indexable inserts.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Verify shank bore diameter and turret pocket clearance before installation to confirm proper fit. Follow the machine tool manufacturer and ISCAR tooling assembly guidelines when torquing clamping screws to avoid insert or pocket damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.197 inches\u003c\/li\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: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 0.986 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.58 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\u003eToolholder Style\u003c\/strong\u003e: HELII\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, GRIP Full Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO groups H, K, M, N, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.65 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: 2500536\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51746105884978,"sku":"2500536","price":322.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a5dcefaf460678f92c5fb8182b50f28.jpg?v=1788866495","url":"https:\/\/voomisupply.com\/products\/iscar-2500536-internal-grooving-toolholder-heli-grip","provider":"Voomi Supply","version":"1.0","type":"link"}
