Identified by ANSI code CCMT32.51 and ISO code CCMT09T304, it features an 80-degree diamond (rhombic) insert shape with a positive side clearance and a neutral hand orientation. The CVD coating and ACP15K grade deliver high to moderate wear resistance combined with toughness, making this insert effective across a range of workpiece materials. The corner radius measures 0.40 mm (0.0157 inches) and the insert thickness is 3.97 mm (0.1563 inches). It is held in the toolholder via a screw-clamp method and belongs to the CI series.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning applications on steel, stainless steel, and cast iron workpieces, corresponding to ISO material group codes P, M, and K. The WSF+ chip breaker geometry is optimized for finishing and semi-finishing cuts where controlled chip flow and surface finish are priorities. Maximum depth of cut is 2.25 mm (0.0886 inches). It is typically installed by machinists and CNC programmers working in production turning, job shop, and maintenance machining environments. The inscribed circle measures 9.53 mm (0.3752 inches), confirming compatibility with standard CCMT seat toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI code CCMT32.51 and ISO code CCMT09T304 for direct cross-reference ordering\u003c\/li\u003e\n\u003cli\u003eCVD-coated ACP15K carbide grade for wear resistance across steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (C) with positive side clearance for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eWSF+ chip breaker geometry suited for finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method for secure, repeatable seating in the toolholder pocket\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits both left- and right-hand toolholder configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard CCMT32.51 screw-on toolholders accepting an 80-degree diamond insert with a 9.53 mm inscribed circle and positive clearance geometry.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully into the toolholder pocket and tighten the clamping screw to the toolholder manufacturer-specified torque using the appropriate Torx or hex key. Inspect the insert seat and clamp for wear or debris before seating a new insert to ensure accurate positioning and prevent premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT32.51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT09T304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80-Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACP15K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3.97 mm (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (0.3752 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 2.25 mm (0.0886 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WSF+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: P (Steel), M (Stainless Steel), K (Cast Iron)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Size Code\u003c\/strong\u003e: 32.51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Size Code\u003c\/strong\u003e: 09T304\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: 75551739\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733023654194,"sku":"75551739","price":176.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9d79e465700ef4227f157ccdd07d2ed_97010fce-6589-4d41-877b-4b3f61357cfb.jpg?v=1788750654","url":"https:\/\/voomisupply.com\/products\/accupro-75551739-ccmt32-51-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
