Manufactured to the TPCG320.5 insert style standard, this triangular insert carries HERTEL grade HT630B cermet material and meets C8 material grade classification. It features a 60-degree included angle, a 0.007 inch corner radius, and a 3\/8 inch inscribed circle diameter. The 11-degree relief angle supports efficient chip clearance during cutting. Left-hand orientation and screw-type holding make it a direct-fit replacement for compatible boring bars and toolholders. Machinists and toolroom technicians working in production or maintenance turning environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finish and semi-finish boring operations on ferrous and non-ferrous metals where cermet uncoated tooling is specified. The TPCG-style triangular geometry performs well in applications requiring consistent surface finish and dimensional accuracy at moderate to high cutting speeds. The left-hand insert orientation suits specific boring bar configurations where right-hand inserts are not compatible. Screw clamping via the TPCG holding method provides secure seating under continuous cutting loads. Catalog reference number for this insert is TPCG3205L. Minimum order quantity for this item is 10 pieces, sold individually per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCermet uncoated construction in HT630B grade for consistent wear resistance without coating\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape with 11-degree relief angle for effective chip clearance\u003c\/li\u003e\n  \u003cli\u003e0.007 inch corner radius for finish and semi-finish boring surface quality\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle diameter, 1\/8 inch thickness for standard TPCG toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation with screw-type holding method\u003c\/li\u003e\n  \u003cli\u003eC8 material grade classification for hard and abrasive workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for TPCG-style boring bars and toolholders accepting a 3\/8 inch inscribed circle triangular insert with screw clamping.

Ensure the machine spindle is fully stopped and all energy sources are locked out before changing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure. Inspect the insert pocket and clamping screw for wear or debris before seating the 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 Size Code\u003c\/strong\u003e: 320.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\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\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inch (0.1270 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\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT630B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\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\u003eManufacturers Catalog Number\u003c\/strong\u003e: TPCG3205L\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 inches\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: H59875500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743889883442,"sku":"H59875500","price":504.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b150c990ff319d9fbb964f974bc698e.jpg?v=1788850863","url":"https:\/\/voomisupply.com\/products\/hertel-h59875500-boring-insert-tpcg320-5-ht630b-cermet","provider":"Voomi Supply","version":"1.0","type":"link"}
