It features a parallelogram shape with a 70-degree included angle, two cutting edges, and a right-hand orientation. The insert measures 17.50 mm (0.6890 inches) in length, 8.50 mm (0.3310 inches) in width, and 4.50 mm (0.1772 inches) in thickness. A PVD-applied TiAlN plus TiN multilayer coating provides heat and wear resistance at the cutting edge. The 15-degree positive rake angle and honed cutting edge style reduce cutting forces when machining difficult materials. Licensed HVAC technicians, machinists, and tooling specialists working with CNC milling platforms install this insert.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for aggressive milling of steel, stainless steel, superalloys, and titanium — workpiece material codes P, M, and S. The GD chip breaker geometry promotes controlled chip evacuation in interrupted and continuous cuts. It is secured via screw-holding method into compatible milling toolholders. Typical applications include face milling, shoulder milling, and profiling operations on CNC machining centers in manufacturing and job-shop environments where tool life and edge security in tough alloys are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN plus TiN coating for extended tool life in steel and superalloy cutting\u003c\/li\u003e\n\u003cli\u003ePositive 15-degree rake angle reduces cutting forces and heat generation\u003c\/li\u003e\n\u003cli\u003eGD chip breaker promotes reliable chip control across a range of depths of cut\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style improves edge toughness and reduces micro-chipping\u003c\/li\u003e\n\u003cli\u003eRight-hand, single-sided insert with 2 usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eCompatible with Mill 1-14 cutter series for broad toolholder availability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the Mill 1-14 cutter series.

Ensure the milling spindle is fully de-energized and locked out before seating or removing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to achieve proper screw-clamp torque without over-tightening. Inspect the pocket seating surface for debris or damage before installing a new insert to avoid premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: EDCT140431PDERGD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: EC1431EGD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCSM40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: EDCT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiAlN plus TiN (PVD)\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 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\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 70 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 17.50 mm (0.6890 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8.50 mm (0.3310 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.50 mm (0.1772 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1220 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1339 inches (0.13 mm nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: Mill 1-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01268 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6171591\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733142470962,"sku":"6171591","price":220.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de094708fe4c4fb58ba66377e00f1a5e.jpg?v=1788751822","url":"https:\/\/voomisupply.com\/products\/kennametal-6171591-milling-insert-edct140431pdergd-kcsm40","provider":"Voomi Supply","version":"1.0","type":"link"}
