Designed for precision boring operations, the insert features a 60-degree included angle, a 0.007-inch corner radius, and an 11-degree relief angle with a positive rake geometry. The CG5 micrograin carbide grade provides wear resistance across a broad range of workpiece materials. With three cutting edges per insert and screw-style holding, this neutral-hand insert suits high-volume production environments as well as job-shop boring applications. Licensed machinists and CNC operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for universal primary workpiece materials, covering steel, stainless, non-ferrous, and superalloys (ANSI material codes M, N, P, S), with cast iron (code K) as a rated secondary material. It fits boring bars and toolholders designed for TPHH-style inserts with a 0.25-inch inscribed circle. The TPHH21505 geometry is standardized under both ANSI code TPHH21505 and ISO code TPHH110202, allowing cross-reference across tooling catalogs. Typical applications include finish and semi-finish boring on lathes, machining centers, and dedicated boring machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin CG5 carbide grade for consistent edge integrity across diverse materials\u003c\/li\u003e\n  \u003cli\u003ePVD-applied titanium nitride (TiN) coating for improved surface hardness and tool life\u003c\/li\u003e\n  \u003cli\u003e60-degree triangle insert shape with three usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003ePositive rake and 11-degree relief angle reduce cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003e0.007-inch corner radius suits semi-finish and finish boring tolerances\u003c\/li\u003e\n  \u003cli\u003eScrew-style insert holding for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for toolholders accepting TPHH-style inserts with a 0.25-inch inscribed circle and screw-style clamping.

Power down and lock out the machine spindle before seating or removing the insert. Use the manufacturer-specified torx or hex key to tighten the clamping screw to toolholder specifications  -  do not over-torque. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert to ensure correct seating and edge repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPHH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.4330 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.4330 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2858 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CG5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (Steel, Stainless, Non-Ferrous, Superalloys)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: TPHH21505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPHH110202\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: WIDIA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2823914\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67909731189042,"sku":"2823914","price":38.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87a02fa35a5c34ef499cd42edda0857f.jpg?v=1791190509","url":"https:\/\/voomisupply.com\/products\/widia-2823914-boring-insert-tphh21505-cg5-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
