This round-profile insert features a 1\/2 inch (0.5000 inch) inscribed circle and a 5\/16 inch (0.3150 inch) thickness, ground to a G tolerance with a C clearance angle and 7-degree relief. The titanium nitride (TiN) coating is applied via PVD process over a ceramic substrate, improving surface hardness and wear resistance at elevated cutting temperatures. Grade HP610CA is formulated for demanding turning applications where tool life and edge stability are priorities. The insert is neutral hand, making it suitable for both left- and right-hand toolholders. Total weight is 0.12 pounds per insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finish and semi-finish turning of hardened steels, cast irons, and high-temperature alloys in production machining environments. The round insert shape (shape code R) provides multiple cutting edges per insert, reducing per-edge tooling cost on high-volume runs. The RCGX style designation indicates a clamp-held, round, 7-degree relief insert with an X chip breaker geometry. It is used in both horizontal and vertical CNC turning centers as well as manual lathes equipped with compatible RCGX toolholders. Typical applications include shaft turning, bore finishing, and contour work where a round insert profile provides continuous edge engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic insert material with TiN coating applied via PVD process for enhanced wear resistance\u003c\/li\u003e\n  \u003cli\u003eRound insert shape (code R) delivers multiple usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch inscribed circle (12.70 mm) with 5\/16 inch insert thickness\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits both left- and right-hand RCGX toolholders\u003c\/li\u003e\n  \u003cli\u003eX chip breaker geometry supports consistent chip control in turning operations\u003c\/li\u003e\n  \u003cli\u003eG tolerance and C clearance code ensure precise fitment in standard RCGX pockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard RCGX-style clamp-held turning toolholders with a 1\/2 inch inscribed circle insert pocket.

Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or indexing the insert. Use the appropriate torx or hex key to tighten the clamp screw to the toolholder manufacturer's specified torque. Inspect the insert pocket seat and clamp for damage or debris before installing a new insert edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RCGX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round (code R)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HP610CA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inch \/ 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/16 inch (0.3150 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 104\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8850557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730484887858,"sku":"8850557","price":781.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc9a7f7d3e8e0c52322367d607171bbb.jpg?v=1788718294","url":"https:\/\/voomisupply.com\/products\/hertel-8850557-ceramic-turning-insert-rcgx-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
