Built from steel with a right-hand cutting orientation, it accepts two 16NR-compatible inserts secured by a clamp-style holding method. The shank measures 1.339 inches in height and 1.427 inches in width, with an overall length of 12 inches. Coolant-through capability is included via axial concentric entry, supporting chip evacuation and tool life in deep-bore threading applications. Licensed machinists and CNC operators working in production turning environments will find this holder ready for direct setup.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for internal threading and turning on both ferrous and non-ferrous workpieces in production and job-shop environments. The 1.7-inch minimum bore diameter determines the smallest bore it can enter, making it appropriate for medium-to-large diameter internal thread work. It belongs to the SECO Snap Tap series and is configured for 3\/8-inch insert inscribed circle (IC) inserts coded 16NR. The CN toolholder style and clamp insert holding method are standard in high-volume turning setups where insert indexing speed matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal threading and turning capability in a single right-hand holder\u003c\/li\u003e\n\u003cli\u003eAccepts 16NR inserts with 3\/8-inch inscribed circle for standard thread profiles\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eCoolant-through design with axial concentric entry for improved chip control\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and vibration resistance in deep-bore applications\u003c\/li\u003e\n\u003cli\u003ePart of the SECO Snap Tap series for consistent insert-change workflows\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 16NR-compatible indexable inserts with a 3\/8-inch inscribed circle.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Confirm proper insert seating and clamp torque per the insert manufacturer's specification before cutting. Connect the coolant supply line to the axial concentric entry port and verify flow before initiating the threading cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\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: 1.339 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1.427 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 10 inches (254 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 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: 1.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.9 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\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Threading, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.94 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: 02562787\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558996934962,"sku":"02562787","price":697.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecfdbe96c12c09eb811052edd846478d.jpg?v=1786425292","url":"https:\/\/voomisupply.com\/products\/seco-02562787-indexable-threading-toolholder-internal","provider":"Voomi Supply","version":"1.0","type":"link"}
