Manufactured in a 60-degree triangle (TDHB) style with a 15-degree relief angle, this insert delivers clean, consistent cutting geometry on ferrous and non-ferrous workpieces. The cermet substrate at material grade C8 provides a balance of wear resistance and edge toughness suited for finishing and semi-finishing passes. Screw-type insert holding keeps the insert securely indexed in compatible boring bar toolholders. At 0.03 pounds, it is a lightweight precision cutting tool intended for machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal diameter boring applications requiring tight tolerances and good surface finish. The TDHB style with a 1\/64-inch corner radius is well matched to light to moderate depth-of-cut finishing passes in steel, stainless, and similar materials. It fits into TDHB-style boring bar holders that accept the 1.280.751 insert size code. Typical installation environments include production machine shops, toolrooms, and maintenance machining applications where cermet grade inserts are specified for their thermal and wear performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60-degree triangle shape with TDHB insert style for internal boring applications\u003c\/li\u003e\n\u003cli\u003eCermet uncoated substrate at material grade C8 for wear-resistant finishing cuts\u003c\/li\u003e\n\u003cli\u003e1\/64-inch (0.0150-inch) corner radius for controlled surface finish\u003c\/li\u003e\n\u003cli\u003e5\/32-inch (0.1600-inch) inscribed circle diameter defining insert size\u003c\/li\u003e\n\u003cli\u003e15-degree relief angle reduces rubbing and extends edge life\u003c\/li\u003e\n\u003cli\u003eScrew-type holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit TDHB-style boring bar toolholders accepting insert size code 1.280.751 with screw-type insert clamping.

Power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torque wrench and insert screw to seat the insert fully in the pocket without overtightening. Inspect the insert pocket and seating surface for chips or wear before installing a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TDHB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1.280.751\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: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT630B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/32 inch (0.1600 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0150 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/64 inch (0.0469 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 1.5 inches W x 0.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Package 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: H59873497\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730356076850,"sku":"H59873497","price":265.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99a3fe7b8a3ddb0577527194d3282b7f.jpg?v=1788715955","url":"https:\/\/voomisupply.com\/products\/hertel-h59873497-boring-insert-triangle-cermet-5-32-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
