It features an LNKU insert style with a rectangular shape and carries the ACK15 manufacturer grade with a CVD coating for wear resistance at elevated cutting temperatures. The insert has a positive rake geometry and a 0-degree relief angle, making it suited for demanding milling operations on ferrous and non-ferrous materials. With four available cutting edges on a double-sided configuration, this insert offers extended tool life between indexing events. It is installed and indexed by licensed machinists and toolroom technicians working with compatible milling cutter bodies.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in milling applications where controlled chip formation and consistent surface finish are required. The CI series designation and LNKU cutter series compatibility make it appropriate for face milling, shoulder milling, and similar operations in production and job-shop environments. It suits both horizontal and vertical machining center setups. The maximum depth of cut is 0.4724 inches (12.00 mm), which positions it for medium-duty material removal passes. Right-hand cutting orientation should be confirmed against the cutter body before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with CVD coating for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eDouble-sided insert with four cutting edges for maximum indexing value\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0315 inches (0.80 mm) for controlled edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.4724 inches (12.00 mm) supports medium-duty milling passes\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting method ensures secure seating in the cutter pocket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with LNKU cutter series milling bodies.

Use the manufacturer-specified torx or hex key to seat the clamping screw to the cutter body recommendation. Inspect the insert pocket for debris or damage before seating a new insert. Do not use damaged or chipped inserts, as they can fracture during cutting and create a hazard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LNKU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LNKU120608ERCCM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACK15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2669 inches (6.78 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: LNKU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54029988\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728052748594,"sku":"54029988","price":303.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7efc1eceb8f8d5f772038ca11f589eac.jpg?v=1788687119","url":"https:\/\/voomisupply.com\/products\/accupro-54029988-lnku-milling-insert-size-12-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
