Built on the Self Grip series platform, it accepts a range of GFN and GFR\/L insert styles secured without fasteners through a self-gripping clamping method. The toolholder handles workpieces up to 2.5 inches in diameter and accommodates inserts with widths from 0.139 inches up to 0.178 inches. The shank measures 1 inch in height by 1 inch in width, and the overall length is 5.9 inches. It is installed by machinists and tool-room technicians on production and job-shop turning equipment.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for light to medium parting and grooving work in residential machine shops, production facilities, and contract machining operations. The left-hand orientation positions the cutting edge for specific spindle-direction and approach configurations common in OD grooving and cutoff applications. Compatible insert families cover a wide range of groove profiles, making this holder adaptable across multiple part geometries without changing the body. The self-grip clamping system allows quick insert indexing without additional clamping hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand holder orientation for OD grooving and parting setups\u003c\/li\u003e\n\u003cli\u003eSelf Grip clamping method — no separate clamp screw required for insert retention\u003c\/li\u003e\n\u003cli\u003eAccepts GFN-A, GFN-C, GFN-J, GFN-M, GFN-U, GFN-W, GFR\/L-C, GFR\/L-J, GFR\/L-W, and GFR-U inserts\u003c\/li\u003e\n\u003cli\u003eMaximum workpiece diameter of 2.5 inches suits most light-duty parting applications\u003c\/li\u003e\n\u003cli\u003eInsert width range of 0.139 to 0.178 inches covers common groove and cutoff widths\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for CAM and tool management integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with GFN-A, GFN-C, GFN-J, GFN-M, GFN-U, GFN-W, GFR\/L-C, GFR\/L-J, GFR\/L-W, and GFR-U indexable inserts.

Power down and lock out the machine spindle before changing or indexing inserts. Seat the shank fully in the turret or toolpost block and torque all clamping fasteners to the machine manufacturer's specification. Verify tool centerline height before making the first cut, as incorrect height directly affects parting performance and insert life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: SGTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Workpiece Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Insert Width\u003c\/strong\u003e: 0.139 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Insert Width\u003c\/strong\u003e: 0.178 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Self Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Self Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving, Parting, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: SGTFL 25.4-4\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: 2300815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51734598058290,"sku":"2300815","price":278.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e50ed0beecd3106532504935b171dccb.jpg?v=1788763670","url":"https:\/\/voomisupply.com\/products\/iscar-2300815-indexable-cutoff-toolholder-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
