Built to the SGTH toolholder style, it accepts Self Grip series inserts and clamps them securely using a self-grip holding method that eliminates the need for clamping screws. The holder accommodates workpieces up to 1.18 inches in diameter and accepts inserts ranging from 0.079 inches to 0.094 inches in width. With an overall length of 4.33 inches and a blade width of 0.063 inches, it delivers a rigid, low-profile setup suited to tight clearance cutoff work. Machinists and toolroom technicians install this holder in standard square shank tool stations.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for cutoff and parting applications in production turning environments, including both manual turret lathes and CNC turning centers. The compact head dimensions — 0.62 inches in height and 0.71 inches in length — make it appropriate for machines with limited cross-slide clearance. The 0.5-inch shank height and 0.375-inch shank width fit standard rectangular boring bar pockets and quick-change tool posts commonly found in light to mid-size turning equipment. No coolant-through capability is present on this holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand orientation for standard OD cutoff and parting operations\u003c\/li\u003e\n\u003cli\u003eSelf Grip insert clamping — no clamping screw required for insert indexing\u003c\/li\u003e\n\u003cli\u003eAccepts GTN 2.., GTN 2.4.., GTR 2.., and GTR 2.4.. series inserts\u003c\/li\u003e\n\u003cli\u003eMaximum workpiece diameter of 1.18 inches keeps tool engaged on small-to-mid diameter stock\u003c\/li\u003e\n\u003cli\u003eBlade width of 0.063 inches minimizes material loss per cutoff pass\u003c\/li\u003e\n\u003cli\u003eOverall length of 4.33 inches provides sufficient reach for standard tool post mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with GTN 2.., GTN 2.4.., GTR 2.., and GTR 2.4.. series inserts.

Power down and lock out the machine spindle before mounting or removing the toolholder from the turret or tool post. Verify shank pocket dimensions match the 0.5-inch height and 0.375-inch width before seating the holder. Insert indexing requires no tools with the self-grip clamping method — follow the insert manufacturer's procedure for seating and releasing inserts to avoid damage to the grip pocket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: SGTH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Workpiece Diameter\u003c\/strong\u003e: 1.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Insert Width\u003c\/strong\u003e: 0.079 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Insert Width\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 0.063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.33 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\u003eCutting Tool Application\u003c\/strong\u003e: Cut-Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Self Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Codes\u003c\/strong\u003e: GTN 2.., GTN 2.4.., GTR 2.., GTR 2.4..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Reference\u003c\/strong\u003e: SGTHR 12.7-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 2300912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51729627447602,"sku":"2300912","price":215.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/400c00ccdc24625ca02f820b69751dfc.jpg?v=1788706920","url":"https:\/\/voomisupply.com\/products\/iscar-2300912-indexable-cutoff-toolholder-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
