It uses a T15 Torx drive and an M4 thread, providing positive engagement and reliable clamping torque without fastener slip during high-speed milling operations. The flat head profile seats flush against the insert pocket, keeping the cutting geometry consistent from one insert change to the next. At 8.00 mm overall length, this screw is sized specifically for the WaveMill series insert pocket geometry. Machinists and toolroom technicians working with Sumitomo indexable milling tools will keep these screws on hand as consumable service hardware.\u003c\/p\u003e\n\u003cp\u003eThis insert screw is used in indexable milling applications where a Torx-drive M4 fastener is required to clamp inserts into the toolholder pocket. It is part of the WaveMill series tooling system and is suited for production milling on machining centers and CNC mills. Replacing worn or damaged clamping screws is a routine part of indexable toolholder maintenance, and using the correct OEM-spec screw ensures proper insert seating and full clamping force. A single screw is included per package, allowing precise stock replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eT15 Torx drive for positive, slip-resistant engagement during insert changes\u003c\/li\u003e\n  \u003cli\u003eM4 thread size matches WaveMill series milling cutter toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eFlat head type seats flush to maintain correct insert positioning\u003c\/li\u003e\n  \u003cli\u003e8.00 mm overall length matched to WaveMill insert pocket depth\u003c\/li\u003e\n  \u003cli\u003eSold individually for precise replacement stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SUMITOMO WaveMill series indexable milling cutters requiring an M4 thread, T15 Torx, flat-head insert clamping screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert screw replacement is performed by machinists or toolroom technicians during routine indexable insert changes. Ensure the milling cutter is fully removed from the spindle and secured before servicing. Use a calibrated T15 Torx key or driver and tighten to the toolholder manufacturer specification — do not exceed recommended torque, as overtightening can damage the insert pocket threads. Inspect the screw threads and pocket threads for wear or contamination before reinstalling any insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Type\u003c\/strong\u003e: Insert Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Torx T15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Milling Cutter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: WaveMill\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.646 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161500\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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2G00155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51732378583346,"sku":"2G00155","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09cb49ac26a1d0e27ca56558d3512df4_6e06b493-88ed-4845-9d9d-538cd830e55b.jpg?v=1788742240","url":"https:\/\/voomisupply.com\/products\/sumitomo-2g00155-insert-screw-t15-torx-m4-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
