It accepts one STN27-style insert secured by a screw-clamp holding method, delivering consistent thread geometry across a cutting diameter of 1.18 inches. With a maximum hole depth of 2.03 inches and through-coolant capability, this tool manages chip evacuation and heat control during threading operations. The K118 toolholder style and a neck diameter of 0.945 inches provide clearance in tighter bore applications. Licensed machinists and CNC programmers use this tool in horizontal and vertical machining centers where thread milling is preferred over tapping.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for both internal and external threading applications on machining centers capable of helical interpolation. It works across a range of materials where thread milling offers advantages over tapping, including interrupted cuts, blind holes with minimal thread runout, and applications requiring a single tool to cut multiple thread pitches. Through-coolant delivery supports performance in deeper threading passes up to 2.03 inches. The 1-flute design reduces cutting forces and is appropriate for threading operations in medium to high-strength workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal and external threads in a single tool using helical interpolation\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design for active chip evacuation and heat management at the cutting zone\u003c\/li\u003e\n\u003cli\u003eAccepts one STN27 insert with a 5\/8-inch inscribed circle, held by a clamp screw for quick insert changes\u003c\/li\u003e\n\u003cli\u003eK118 toolholder style with 0.945-inch neck diameter provides bore clearance in tight applications\u003c\/li\u003e\n\u003cli\u003e1-flute configuration reduces radial cutting forces during threading passes\u003c\/li\u003e\n\u003cli\u003eOverall length of 4.38 inches suits standard toolholder projection in most machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with STN27-series threading inserts with a 1.06-inch insert size and a 5\/8-inch inscribed circle.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before mounting or removing the toolholder. Confirm through-coolant passages are clear and that machine coolant pressure is within the range specified by the machining center manufacturer before cutting. Verify helical interpolation programming and thread lead accuracy in the CNC program prior to first article threading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 2.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.945 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 1.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: STN27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: K118\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: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\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: 0.85 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: 1280548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749447631154,"sku":"1280548","price":571.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e3bf6e864c9339757b9d92df20850da.jpg?v=1788906223","url":"https:\/\/voomisupply.com\/products\/kennametal-1280548-indexable-thread-mill-1-18in-cut-dia","provider":"Voomi Supply","version":"1.0","type":"link"}
