Formed in a 60-degree triangle shape with the TCMT style and TN60 manufacturer grade, this insert features a positive rake angle and a 7-degree relief angle that reduce cutting forces and promote clean chip evacuation. The inscribed circle measures 7\/32 inches (0.2188 inches), insert thickness is 3\/32 inches (0.0940 inches), and the corner radius is 1\/32 inches. With three cutting edges per insert, it delivers extended service life per unit. Licensed machinists and tooling technicians install this insert in indexable drill toolholders on CNC and manual machine tools.\u003c\/p\u003e\u003cp\u003eThis insert is suited for steel machining applications, carrying primary workpiece material codes N and P. It fits within the SD series platform and conforms to ANSI code TCMT1.81.52HP TN60 and ISO code TCMT1.81.52HP. Material grades C2, C3, C4, C6, C7, and C8 apply, making it appropriate for a broad range of ferrous cutting conditions in both production and job-shop environments. The HP chipbreaker geometry is optimized for controlled chip formation during drilling cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCermet uncoated substrate with TN60 grade for steel cutting performance\u003c\/li\u003e\n\u003cli\u003e60-degree triangle shape with 3 usable cutting edges for cost efficiency\u003c\/li\u003e\n\u003cli\u003ePositive rake and 7-degree relief angle reduce cutting forces\u003c\/li\u003e\n\u003cli\u003eHP chipbreaker for controlled chip formation and evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO insert standards for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eNeutral cutting direction suits standard drilling and boring setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for TCMT-style indexable drill toolholders within the SD series; compatible with material grades C2, C3, C4, C6, C7, and C8 applications per ANSI code TCMT1.81.52HP TN60 and ISO code TCMT1.81.52HP.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked before changing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the insert clamp to the correct seating torque per the toolholder documentation. Inspect the insert pocket and seating surfaces for debris or damage before seating the new insert. Do not exceed the recommended cutting parameters for the TN60 cermet grade when programming feed rates and speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\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: TN60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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\u003eInscribed Circle\u003c\/strong\u003e: 7\/32 inches (0.2188 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/32 inches (0.0940 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.3540 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 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\u003eChipbreaker\u003c\/strong\u003e: HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 18152\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: N, P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4, C6, C7, C8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: TCMT1.81.52HP TN60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT1.81.52HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KYOCERA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TSJ89149\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA","offers":[{"title":"Default Title","offer_id":51731141558578,"sku":"TSJ89149","price":135.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a531f2859484e5fe7c5115496d9dcaa5.jpg?v=1788727448","url":"https:\/\/voomisupply.com\/products\/kyocera-tsj89149-indexable-drill-insert-tcmt18hp-tn60","provider":"Voomi Supply","version":"1.0","type":"link"}
