Carrying the ISO designation SCMT09T304, this insert features a 90-degree included angle, a 7-degree relief angle, and a 0.40 mm (0.0157 inch) corner radius that balances surface finish quality with edge strength. The substrate is CVD-coated carbide, grade ACM20P, engineered for high wear-resistance to moderate wear-resistance and toughness across steel and stainless steel workpiece materials. Machinists and toolroom operators install it using a screw-clamp holding method. With four cutting edges per insert and a positive side clearance geometry, it delivers consistent, repeatable performance per edge.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel and stainless steel components in production and jobshop environments. The SCMT style and positive side clearance geometry make it appropriate for moderate to light cutting depths, with a maximum depth of cut of 3.00 mm (0.1181 inch). The WM+ chip breaker geometry promotes reliable chip control during continuous and interrupted finish turning passes. It fits standard SCMT-compatible toolholders and is a practical choice for machinists maintaining CNC turning centers or manual turret lathes where consistent insert interchangeability is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD-coated ACM20P carbide grade rated for high to moderate wear-resistance on steel (P) and stainless steel (M) workpiece materials\u003c\/li\u003e\n\u003cli\u003eSquare insert shape (S) with 90-degree included angle and 7-degree relief angle for positive clearance geometry\u003c\/li\u003e\n\u003cli\u003e0.40 mm corner radius balances surface finish quality with cutting-edge durability\u003c\/li\u003e\n\u003cli\u003eWM+ chip breaker geometry promotes chip control in finish and moderate turning applications\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert extend overall tooling economy\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method provides rigid, repeatable insert seating in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for SCMT09T304-style insert seats; compatible with any ANSI SCMT32.51 screw-clamp toolholder accepting a square insert with a 0.1772-inch hole diameter and 0.1563-inch insert thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and toolroom technicians following standard CNC or manual lathe lockout and energy-isolation procedures before any insert change. Seat the insert firmly against the toolholder pocket walls before tightening the clamp screw to the toolholder manufacturer's specified torque. Inspect the insert pocket and seating surface for chips or debris that could rock the insert and cause premature edge failure. Dispose of worn carbide inserts according to applicable local regulations for metal cutting waste.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SCMT09T304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: S - Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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: 0.1772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACM20P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI Code SCMT32.51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 75515528\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739949072690,"sku":"75515528","price":181.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c408691174b24a3d990246a7a592b59_c9dda1f2-2e82-4871-baa3-b14e073437e7.jpg?v=1788820647","url":"https:\/\/voomisupply.com\/products\/accupro-75515528-scmt09t304-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
