It features a Physical Vapor Deposition (PVD) TiN coating over a cermet substrate, which provides wear resistance and thermal stability during continuous and light interrupted cuts. The insert has a neutral hand orientation, a positive rake angle of 15 degrees, and a corner radius of 0.0312 inches (1\/32 inch). The inscribed circle measures 0.375 inches (3\/8 inch) and the insert thickness is 0.1875 inches (3\/16 inch). Machinists and CNC lathe operators install this insert in compatible WNMG-style toolholders for finishing and semi-finishing operations on steel and hardened materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning operations on ferrous metals, including medium-carbon and alloy steels, where a fine surface finish and tight dimensional tolerances are required. The G chip breaker geometry and 15-degree positive rake angle help control chip flow and reduce cutting forces during light-to-moderate depth-of-pass operations. It is commonly used in production turning environments on CNC lathes and manual engine lathes equipped with clamp-and-pin style WNMG toolholders. The 80-degree trigon (W) shape provides two usable cutting edges per insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHP225CR cermet grade with PVD TiN coating for extended tool life on steel finishing cuts\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (15 degrees) reduces cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003eG chip breaker geometry promotes controlled chip formation in light-to-medium cuts\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert fits left- or right-hand WNMG-style toolholders\u003c\/li\u003e\n  \u003cli\u003e80-degree trigon shape (W) delivers two cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method ensures rigid, repeatable seating in the pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for WNMG332-style insert pockets using clamp-and-pin holding systems.

Seat the insert fully into the pocket before engaging the clamp and pin; an improperly seated insert can fracture under cutting load. Inspect the toolholder pocket for wear or damage before installing a new insert. Follow the toolholder manufacturer torque recommendations for the clamp screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG332BH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HP225CR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (80 degrees, W)\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: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 8851934\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748377297202,"sku":"8851934","price":186.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfa6434ff557943109848682eaff38bc.jpg?v=1788893112","url":"https:\/\/voomisupply.com\/products\/hertel-8851934-turning-insert-wnmg332bh-hp225cr-cermet","provider":"Voomi Supply","version":"1.0","type":"link"}
