It belongs to the Top Notch series and accepts N.3R inserts held in place by a clamp-style insert holding method. The shank measures 1 inch wide by 1 inch tall (25.4 x 25.4 mm) with an overall length of 6 inches (152.4 mm). This toolholder is designed for grooving and threading applications on CNC lathes and turning centers. Licensed machinists and toolroom technicians are the primary users. The head length is 0.75 inches (19.05 mm) and the maximum depth of cut is 0.21 inches (5.33 mm).\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external threading and grooving operations in production turning environments, including both job shop and production floor settings. Its left-hand orientation makes it appropriate for applications that require cutting away from the chuck or in configurations where a right-hand holder cannot access the workpiece geometry. It is flagged as a multi-use tool, supporting both grooving and threading with compatible Top Notch series N.3R inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal, left-hand configuration for threading and grooving operations\u003c\/li\u003e\n\u003cli\u003eAccepts N.3R inserts secured by a clamp-style holding method\u003c\/li\u003e\n\u003cli\u003eTop Notch series toolholder style NE for consistent insert positioning\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.21 inches (5.33 mm)\u003c\/li\u003e\n\u003cli\u003eMulti-use capability supporting both grooving and threading\u003c\/li\u003e\n\u003cli\u003e1 inch x 1 inch square shank for rigid setup in standard tool posts and turrets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with N.3R inserts in the Top Notch series.

Power down and lock out the machine before mounting or removing the toolholder. Secure the shank fully in the tool post or turret block to the recommended clamping depth to prevent deflection under cutting loads. Inspect the insert pocket and clamping surfaces for chips or debris before seating the N.3R insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: NE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: N.3R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1 inch (25.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch (25.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.21 inches (5.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving, Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.63 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1097237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730862178610,"sku":"1097237","price":204.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/785e62de9dfee48f4e9249d4c93f3447.jpg?v=1788724028","url":"https:\/\/voomisupply.com\/products\/kennametal-1097237-threading-toolholder-external-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
