The insert features a PVD-applied MEGACOAT surface treatment on a micrograin carbide substrate, delivering wear resistance and edge integrity across a range of cutting conditions. Key dimensional specs include a 0.072-inch cutting width, a maximum depth of cut of 0.094 inches, and an overall length of 0.810 inches. The positive rake geometry and 3-degree lead angle reduce cutting forces on the workpiece. This insert is installed and indexed by licensed machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe PR1215 grade is engineered primarily for steel (ISO P) and secondarily for stainless steel (ISO M). It is suited to finish and semi-finish grooving passes where controlled chip evacuation and consistent groove width are required. The KCGP3072 insert size fits clamp-style toolholders designated for the KCGP series. Typical applications include OD grooving, undercut operations, and snap-ring groove machining on turned components in both low-volume and high-production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate with PVD MEGACOAT coating for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e0.072-inch cutting width with a maximum depth of cut of 0.094 inches\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with 3-degree rake angle and 3-degree lead angle to reduce cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation; clamp-style holding method\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.008 inches for controlled surface finish at groove edges\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ANSI\/ISO code KCGP3072RPR1215\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KCGP-series clamp-style grooving toolholders.

Ensure the machine spindle is fully stopped and locked out before handling or indexing the insert. Inspect the insert seat and clamp for chips or debris prior to seating the new insert to ensure proper clamping force and runout. Dispose of worn inserts according to applicable shop safety protocols for carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: KCGP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3072\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: PR1215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.072 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.075 to 0.100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 0.344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.195 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.810 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.008 inches\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: 3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: MEGACOAT (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: KCGP3072RPR1215\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: 0.21 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (MOQ: 10)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KYOCERA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8850659\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA","offers":[{"title":"Default Title","offer_id":51746330214706,"sku":"8850659","price":444.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e3ea3b930631df8e7937049396dffc5.jpg?v=1788868481","url":"https:\/\/voomisupply.com\/products\/kyocera-8850659-grooving-insert-kcgp3072-pr1215-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
