Manufactured from steel with 13% cobalt material grade, this insert features a Physical Vapor Deposition (PVD) TiN coating that extends cutting edge life and reduces friction during machining. The insert measures 0.5314 inches in length, 0.3149 inches in width, and 0.3543 inches in thickness. With a positive rake angle, a 45-degree included angle, and a single right-hand cutting edge secured by screw-holding method, it delivers controlled, accurate cuts in keyway applications.\u003c\/p\u003e\u003cp\u003eThis insert is intended for right-hand keyway milling operations in industrial and toolroom environments. The 8.00 mm cutting edge effective length and irregular insert shape make it suited for cutting standard metric keyway profiles in ferrous and non-ferrous workpieces. It belongs to the Series 99 product line and is appropriate for machine shops, maintenance facilities, and production environments where keyway broaching or milling is performed regularly. The insert is installed one piece per holder and ordered in a minimum quantity of two units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD TiN coating provides wear resistance and extends cutting edge service life\u003c\/li\u003e\n\u003cli\u003e13% cobalt steel construction for toughness in demanding keyway milling applications\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry reduces cutting forces and improves chip flow\u003c\/li\u003e\n\u003cli\u003e45-degree included angle and irregular shape optimized for keyway profiles\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting method ensures secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eSingle right-hand cutting edge for directional keyway slot cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for Series 99 keyway milling toolholders requiring an 8mm right-hand screw-held insert.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert replacement should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before removing or seating the insert. Use the appropriate torx or hex key driver specified by the toolholder manufacturer to secure the clamping screw  -  do not overtighten. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper seating and avoid premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: Keyway\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 8mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 13% Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Irregular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5314 inches (13.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3149 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.3543 inches (9.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 99\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DUMONT MINUTE MAN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 99407\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DUMONT MINUTE MAN","offers":[{"title":"Default Title","offer_id":67906957246770,"sku":"99407","price":266.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1548df9ca6cef0ec470756879dfa6045.jpg?v=1791172827","url":"https:\/\/voomisupply.com\/products\/dumont-minute-man-99407-keyway-milling-insert-8mm","provider":"Voomi Supply","version":"1.0","type":"link"}
