Manufactured in the TIP style with an IC908 grade carbide substrate and a PVD coating process, this insert delivers consistent thread form accuracy on a range of ferrous and non-ferrous workpiece materials. The partial profile 60-degree thread standard covers both metric and unified thread forms at a 1.25 mm pitch (20 TPI). The MT chipbreaker geometry and Cut Grip series designation make it suited for finishing and semi-finishing passes where chip control and surface finish are priorities for machining professionals.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for external threading applications in production and job-shop turning environments. The 4 mm cutting tip width and 0.15 mm corner radius suit fine-pitch threading on smaller diameter workpieces. Typical users include CNC machinists, tool-and-die shops, and contract manufacturers working to ISO 13399 tooling standards. It is compatible with ISCAR Cut Grip series toolholders designed to accept TIP-style threading inserts in size 4.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC908 carbide grade with PVD coating for extended wear resistance on steel and cast iron (material grades C1, C2, C6, C7)\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree included angle covers metric and unified external thread forms\u003c\/li\u003e\n  \u003cli\u003e1.25 mm pitch (20 TPI) for consistent thread geometry on fine-pitch applications\u003c\/li\u003e\n  \u003cli\u003e0.15 mm (0.0059 inch) corner radius for accurate thread root profile\u003c\/li\u003e\n  \u003cli\u003eMT chipbreaker designed for reliable chip evacuation during threading passes\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13399 cutting tool data representation standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISCAR Cut Grip series toolholders that accept TIP-style threading inserts in size 4.

Seat the insert firmly in the toolholder pocket and verify torque on the clamping screw per the toolholder manufacturer specification before initiating any cutting pass. Inspect the insert seating surface and pocket for chips or debris before installation, as contamination can affect thread form accuracy. Minimum order quantity for this insert is 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TIP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1, C2, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Partial Profile 60 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 1.25 mm (20 TPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Cut Grip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.15 mm (0.0059 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6403302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51731253297458,"sku":"6403302","price":552.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4b91e5f5e4e03b1b4da1903afc7b25e.jpg?v=1788728807","url":"https:\/\/voomisupply.com\/products\/iscar-6403302-threading-insert-ic908-carbide-1-25mm-20-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
