Coated with Titanium Nitride (TiN) via a PVD process, it delivers improved surface hardness and wear resistance over uncoated carbide. The insert features a 60-degree triangular shape with three cutting edges, a 0.375-inch inscribed circle, a 0.125-inch thickness, and a 0.015-inch corner radius. Grade CG5 micrograin carbide provides the substrate. The left-hand cutting direction and positive rake geometry make this insert suited for fine boring passes where surface finish and dimensional accuracy are priorities. A licensed machinist or toolroom technician is the typical installer.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in screw-held boring bar systems requiring a left-hand, TPCG-style triangular insert. It is applicable to a range of secondary workpiece materials including steel, stainless steel, cast iron, and non-ferrous metals. It is well suited for both roughing and finishing passes on CNC turning centers and manual lathes where a positive-rake, chipbreaker-equipped insert is specified. The Series TPHH-L toolholder family is the associated holder series. Maximum depth of cut is 0.42 inches. ANSI code is TPHH321L and ISO code is TPHH160304L.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCG5 micrograin carbide grade with PVD Titanium Nitride coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape with three usable cutting edges\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with integrated chipbreaker for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting direction, screw-held mounting method\u003c\/li\u003e\n  \u003cli\u003e0.015-inch corner radius for balanced edge strength and surface finish\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.42 inches supports both light finishing and moderate stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with TPHH-L series screw-held boring bar toolholders.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex driver. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPCG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CG5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Micrograin Carbide\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: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: TPHH321L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPHH160304L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: WIDIA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2821162\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67906158264626,"sku":"2821162","price":372.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d41b838c4b1c410c58f457409934f8e.jpg?v=1791165401","url":"https:\/\/voomisupply.com\/products\/widia-2821162-boring-insert-tpcg321l-cg5-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
