The tool accepts two STN11-style inserts held by screw clamp, giving machinists a fast and repeatable insert-change process without removing the body from the spindle. At 0.67 inches cutting diameter and 3.42 inches overall length, this tool suits CNC machining centers running thread milling cycles in a wide range of materials. Through-coolant delivery is built in, supporting chip evacuation and thermal control at the cutting zone. The neck diameter of 0.537 inches provides clearance for deep-hole approaches up to 1.34 inches maximum hole depth.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for job shops, tool rooms, and production machining environments where a single tool must handle both internal and external thread forms. The 0.43-inch insert size and 1\/4-inch inscribed circle geometry correspond to the STN11 insert platform, which is commonly stocked for general threading work. Two flutes and through-coolant supply make this tool effective in interrupted cuts, blind holes, and through-hole applications on vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal and external threads in one tool platform\u003c\/li\u003e\n\u003cli\u003eAccepts two STN11 inserts (1\/4-inch inscribed circle, 0.43 inches insert size) for quick changeover\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design supports chip evacuation and edge life in deep-thread applications\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eToolholder style K067 with 0.537-inch neck diameter for clearance in tight-bore entries\u003c\/li\u003e\n\u003cli\u003eMaximum hole depth of 1.34 inches accommodates typical fastener and fitting thread depths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style indexable thread milling body compatible with STN11-platform inserts in the K067 toolholder style.

Ensure coolant supply lines are clear and through-coolant pressure is set per machine specifications before engaging the cut. Power down the spindle and confirm it is at rest before performing any insert change or torque-down of clamping screws. Follow the machine tool builder guidelines and applicable shop safety procedures when handling indexable cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.67 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 1.34 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.42 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.537 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: STN11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: K067\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Threading Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\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: 0.37 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1280494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736886640946,"sku":"1280494","price":525.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4b11e4eb32910494d1120f51d2dcffe.jpg?v=1788781547","url":"https:\/\/voomisupply.com\/products\/kennametal-1280494-indexable-thread-mill-0-67in-cut-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
