It accepts size 1.5 inserts with a 3\/8-inch inscribed circle and is compatible with 16NL insert style. The shank measures 0.65 inches in height and 0.707 inches in width with an overall length of 7 inches. Built from steel, this toolholder features axial concentric coolant entry and through-coolant capability, making it suitable for demanding cutting conditions where heat management is critical. It is installed and used by machinists and CNC turning specialists.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for internal threading and turning applications in both production and job-shop environments. The CN toolholder style and clamp-style insert holding method provide secure insert retention during threading passes. With a minimum bore diameter of 0.95 inches, it is appropriate for mid-range bore work on steel, alloy, and similar materials. The Snap Tap series designation and multi-use capability make it adaptable across a range of threading operations. The 30 mm head length and 0.52-inch center-to-cutting-edge dimension support precise tool positioning in tight bore setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand internal threading orientation for CNC lathe and turning center use\u003c\/li\u003e\n\u003cli\u003eAccepts size 1.5 inserts with 16NL insert compatibility and 3\/8-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eAxial concentric coolant entry with through-coolant support for thermal control\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for secure retention during threading passes\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and durability under intermittent and continuous cuts\u003c\/li\u003e\n\u003cli\u003eMulti-use capability supports both threading and turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with size 1.5 inserts using the 16NL insert style.

Ensure the machine spindle is fully stopped and all axis motion is locked out before mounting or removing the toolholder. Verify insert seating and clamp torque per shop standards before initiating any cutting pass. Confirm bore clearance against the 0.95-inch minimum bore diameter before tool engagement to avoid interference.\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: Left 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: 16NL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 1.5\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\/Diameter\u003c\/strong\u003e: 0.707 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 5.512 inches (140 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.181 inches (30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.52 inches\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\u003eCoolant Through\u003c\/strong\u003e: Yes\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\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\u003eWeight\u003c\/strong\u003e: 0.66 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291800\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: 02562790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564081217842,"sku":"02562790","price":376.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e07a5f0a18baf9d578e698d5bde3632.jpg?v=1786510451","url":"https:\/\/voomisupply.com\/products\/seco-02562790-indexable-threading-toolholder-internal-lh","provider":"Voomi Supply","version":"1.0","type":"link"}
