Built to the A2TZN style, it accepts blades with a 26 mm (1.024 inches) compatible blade height and features a 3\/4 inch (19.05 mm) shank height and 3\/4 inch (19.05 mm) shank width. The overall length measures 3.39 inches (86 mm) and overall height is 1.65 inches. The block is reversible, extending blade and insert life by allowing the holder to be flipped when one side wears. A licensed machinist or CNC lathe operator typically installs and services this tooling.\u003c\/p\u003e\u003cp\u003eThis tool block is suited for production turning environments where repeatable cutoff and grooving performance is required. The neutral insert cutting direction makes it appropriate for standard right-to-left parting passes on a lathe. The A2 Cut-Off series designation indicates compatibility with A2-style indexable blade systems. It is used in both job-shop and high-volume production settings on ferrous and non-ferrous workpieces where secure, rigid tool clamping is critical to part quality and surface finish.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReversible design doubles effective use life of the tool block body\u003c\/li\u003e\n\u003cli\u003eCompatible blade height of 26 mm (1.024 inches) for A2-style cutoff blades\u003c\/li\u003e\n\u003cli\u003e3\/4 inch shank height and 3\/4 inch shank width for standard tool post mounting\u003c\/li\u003e\n\u003cli\u003eNeutral insert cutting direction for conventional parting operations\u003c\/li\u003e\n\u003cli\u003eOverall length of 3.39 inches (86 mm) with overall width of 1.38 inches (35 mm)\u003c\/li\u003e\n\u003cli\u003eNo coolant-through configuration — external coolant application applies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with A2 Cut-Off series indexable blades with a compatible blade height of 26 mm.

Secure all machine power and engage the spindle lock before mounting or adjusting the tool block in the tool post. Ensure the shank seats fully and squarely in the tool holder to prevent chatter or deflection during cutoff passes. Consult the machine tool manufacturer's guidelines and applicable shop safety standards when setting tool height and overhang.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Block Style\u003c\/strong\u003e: A2TZN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A2 Cut-Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Blade Height\u003c\/strong\u003e: 26 mm (1.024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 19.05 mm (0.750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 19.05 mm (0.750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 86 mm (3.39 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 35 mm (1.38 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Height\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Cutting Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReversible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2125 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1878086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755261264178,"sku":"1878086","price":565.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20eacd508a87ebccc78a426b5dee5200.jpg?v=1788952815","url":"https:\/\/voomisupply.com\/products\/kennametal-1878086-cutoff-tool-block-a2tzn-3-4-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
