Built for left-hand orientation, it accepts TAG-series inserts via a clamp-style holding method, delivering secure insert retention during aggressive grooving and parting operations. The toolholder features a 1 x 1 inch square shank, a maximum groove width of 0.374 inches, and a maximum depth of cut of 0.98 inches. Through-coolant capability directs fluid directly to the cutting zone, extending insert life and improving chip evacuation. Machinists and CNC operators in production and job-shop environments install this holder on lathes requiring reliable external grooving performance.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external grooving and cut-off applications in both production turning and job-shop settings. The left-hand configuration positions it for specific spindle orientations or turret stations where right-hand holders are not appropriate. The Sumo-Grip clamping system is engineered for rigidity under the interrupted-cut and high-feed conditions common in grooving and parting work. Compatible inserts include TAG N-C\/W\/M and TAGB\/TAGBA series, providing flexibility across different groove profiles and workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand toolholder orientation for external grooving and cut-off operations\u003c\/li\u003e\n\u003cli\u003eMaximum groove width: 0.374 inches\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 0.98 inches\u003c\/li\u003e\n\u003cli\u003e1 x 1 inch square shank for rigid turret or block-style mounting\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability for improved chip control and insert life\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method compatible with TAG N-C\/W\/M and TAGB\/TAGBA inserts\u003c\/li\u003e\n\u003cli\u003eMeets ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with TAG N-C\/W\/M and TAGB\/TAGBA series inserts.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Verify that the insert and shim seat are clean and free of chips before clamping the insert. Connect the through-coolant supply line according to the machine tool manufacturer's specifications and confirm flow before resuming cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Sumo-Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: TGBH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Cut-Off and Grooving\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal or External\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Groove Width\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.98 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\/Diameter\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\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.84 inches\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: TAG N-C\/W\/M; TAGB\/TAGBA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.637 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153308\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: 2861090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738715226418,"sku":"2861090","price":363.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ac016a50d576cac48b2d2418449d2b4.jpg?v=1788803306","url":"https:\/\/voomisupply.com\/products\/iscar-2861090-grooving-cutoff-toolholder-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
