Built from steel, this right-hand holder accepts two 16NR-compatible inserts secured by a clamp-style holding method. The shank measures 1.15 inches in height and 1.209 inches in diameter, with an overall length of 10 inches. A minimum bore diameter of 1.4 inches defines the smallest hole this tool can reach. Coolant-through capability is supported via axial concentric entry, keeping the cutting zone clear during threading passes. This holder is part of the SECO Snap Tap series and is suited for production turning environments where consistent thread quality and fast insert indexing are priorities.\u003c\/p\u003e\u003cp\u003eThis toolholder is used in internal threading and turning applications on metal-cutting lathes, machining centers, and horizontal boring machines. It is a fit for shops running high-volume threading operations in materials that benefit from coolant delivery directly to the cutting edge. The right-hand configuration and CN toolholder style are standard in many production turning setups. The 3\/8-inch insert inscribed circle and 16NR insert compatibility make it appropriate for threading operations requiring precision insert positioning. Installation is performed by qualified machinists or toolroom personnel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal threading and turning application with right-hand cut direction\u003c\/li\u003e\n\u003cli\u003eAccepts 16NR inserts with 3\/8-inch inscribed circle, secured by clamp holding method\u003c\/li\u003e\n\u003cli\u003eCoolant-through design with axial concentric entry for direct cutting-zone cooling\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity in high-cycle production environments\u003c\/li\u003e\n\u003cli\u003eSnap Tap series with CN toolholder style for repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eMulti-use capability supporting both threading and turning operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 16NR threading inserts sized at 3\/8-inch inscribed circle.

Power down and lock out the machine before mounting or removing the toolholder. Ensure the turret pocket or boring bar bore is clean and within tolerance before seating the shank. Follow insert manufacturer torque guidelines for the clamp screw when indexing or replacing inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Type\u003c\/strong\u003e: Indexable Threading Toolholder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: CN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: 16NR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\/Diameter\u003c\/strong\u003e: 1.209 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 8.032 inches (204 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.811 inches (46 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.78 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Entry Style\u003c\/strong\u003e: Axial Concentric Entry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Threading, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02562786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563682070834,"sku":"02562786","price":516.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f563fb127f20a7cdc04b5ef3ab4e2814.jpg?v=1786501234","url":"https:\/\/voomisupply.com\/products\/seco-02562786-indexable-threading-toolholder-internal","provider":"Voomi Supply","version":"1.0","type":"link"}
