With a cutting diameter of 1.024 inches and a maximum hole depth of 1.69 inches, it handles a wide range of threading applications on machining centers and CNC mills. The tool accepts two STN16-style inserts secured by screw-lock retention and features through-coolant capability to manage heat and chip evacuation during cutting. Overall length is 4.02 inches with a neck diameter of 0.891 inches. Toolholder style is K102. This tool is intended for use by machinists and tool-and-die professionals working in precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThe 1280517 suits both internal and external thread milling operations, making it a versatile choice for job shops, aerospace component manufacturers, and general precision machining. Its two-flute configuration and through-coolant design support consistent thread quality in ferrous and non-ferrous materials. The 3\/8-inch insert inscribed circle (IC) and STN16 insert style are standard indexable formats, allowing straightforward insert replacement without special tooling. Typical applications include threading bores and external bosses where tap breakage risk or thread quality requirements make thread milling preferable to tapping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts both internal and external threads with one tool body\u003c\/li\u003e\n  \u003cli\u003e1.024 inch cutting diameter with 1.69 inch maximum hole depth capacity\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design for heat control and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eAccepts two STN16 indexable inserts with screw-lock retention\u003c\/li\u003e\n  \u003cli\u003eK102 toolholder style with 0.891 inch neck diameter\u003c\/li\u003e\n  \u003cli\u003eTwo-flute geometry for balanced cutting performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with STN16-style indexable inserts with a 3\/8-inch inscribed circle in a K102 toolholder configuration.

Before changing inserts, de-energize and lock out the machine per standard OSHA lockout\/tagout procedures. Confirm insert seating and screw torque per KENNAMETAL tooling specifications before running. Through-coolant port alignment with the spindle coolant supply should be verified prior to operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1.024 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 1.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.891 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: STN16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: K102\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: 0.76 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291800\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1280517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737850544434,"sku":"1280517","price":571.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b84271c93427b9501cd77e75a531454.jpg?v=1788794325","url":"https:\/\/voomisupply.com\/products\/kennametal-1280517-indexable-thread-mill-1-024-in","provider":"Voomi Supply","version":"1.0","type":"link"}
