Manufactured in the RNG43T00825 style, this insert carries the HT601CA ceramic grade and ships uncoated for direct use in high-speed, high-temperature turning applications where ceramic tooling outperforms carbide. With a 1\/2 inch inscribed circle and a 3\/16 inch thickness, it is held in place by a clamp-style toolholder and features a negative rake geometry. Licensed machinists and CNC operators working in production turning environments install this insert for finishing and semi-finishing passes on hardened ferrous materials and cast iron.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations in aerospace, automotive, and general machining environments where ceramic cutting tools provide the thermal resistance and wear life required at elevated cutting speeds. The neutral hand orientation allows use in both right-hand and left-hand toolholders where the RNG round insert style is specified. Round insert geometry provides the highest possible edge strength and is commonly selected for profiling and continuous turning cuts. Sold individually, with a minimum order quantity of 10 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic uncoated cutting material for high-speed turning of hardened and abrasive workpieces\u003c\/li\u003e\n\u003cli\u003eRound insert shape with insert shape code R delivers full 360-degree usable cutting edge\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry increases edge strength and supports interrupted or continuous cuts\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method compatible with standard RNG round insert toolholders\u003c\/li\u003e\n\u003cli\u003eHT601CA manufacturer grade ceramic formulation for thermal stability at elevated surface speeds\u003c\/li\u003e\n\u003cli\u003eNeutral hand designation allows fitment in right-hand or left-hand clamp toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in clamp-style RNG round insert toolholders accepting a 1\/2 inch inscribed circle insert with an RNG43 insert size code and G tolerance class.

Power down and lock out the machine before changing inserts. Handle ceramic inserts carefully as they are brittle and can chip if dropped or impacted. Verify the insert seat and clamp are clean and undamaged before seating the new insert to ensure proper contact and clamping force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RNG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle Code\u003c\/strong\u003e: RNG43-T00825\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT601CA\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: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\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: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 8850559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736279548210,"sku":"8850559","price":296.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01a8854de7a0e7f4d06bac53895dfd6f.jpg?v=1788776957","url":"https:\/\/voomisupply.com\/products\/hertel-8850559-turning-insert-ceramic-round-1-2-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
