It accepts DG-series inserts secured by a clamp-style holding method, providing rigid, repeatable insert location for consistent groove geometry. The toolholder handles a groove width range of 1.9 to 2.5 mm and a maximum depth of cut of 12.7 mm. The 16 x 16 mm square shank and 120 mm overall length suit compact tool blocks and standard outside-diameter boring bars on short-overhang setups. CNC machinists and toolroom technicians are the primary users of this toolholder.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external grooving and cutoff work on metal turning applications including part-off operations, retaining-ring grooves, and undercut profiles. The left-hand orientation positions the cutting edge for specific turret stations or gang-tool configurations where a right-hand holder would interfere. The Do-Grip clamping system is engineered for secure insert seating without the need for a top clamp, keeping the cutting zone open for chip flow. The toolholder conforms to ISO 13399 standards for cutting tool data representation, supporting integration with CAM and tool-management software.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand toolholder style DGT for external grooving and cutoff operations\u003c\/li\u003e\n\u003cli\u003eGroove width range of 1.9 to 2.5 mm accommodates multiple DG insert widths\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 12.7 mm suitable for part-off and deep grooving passes\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for rigid, repeatable insert seating\u003c\/li\u003e\n\u003cli\u003e16 x 16 mm square shank with 100.5 mm shank length fits standard lathe tool blocks\u003c\/li\u003e\n\u003cli\u003eISO 13399 compliant for seamless CAM and tool-management integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible insert families include DGN\/DGNM with J, JS, and JT seat styles and DGR\/L with J, JS seat styles.

Seat the toolholder securely in the turret pocket to the full shank depth and torque the clamping screws to the machine tool manufacturer specification using calibrated tooling. Confirm insert seating and tool offset values in the control before resuming production cuts. Do not exceed the maximum depth of cut or groove width limits specified for the selected insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: External Grooving, Cut-Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Groove Width\u003c\/strong\u003e: 1.9 mm (0.0748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Groove Width\u003c\/strong\u003e: 2.5 mm (0.0984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 12.7 mm (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 16 mm (0.6299 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 16 mm (0.6299 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 100.5 mm (3.957 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 120 mm (4.7244 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 19.7 mm (0.7756 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 19.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility Code\u003c\/strong\u003e: DG..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius Insert\u003c\/strong\u003e: No\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: Do-Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1 pound\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: 2301538\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51753341059378,"sku":"2301538","price":211.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a006b339a153300b37952b2bf0fcd5fd.jpg?v=1788935610","url":"https:\/\/voomisupply.com\/products\/iscar-2301538-grooving-cutoff-toolholder-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
