It features straight flutes and a left-hand cutting direction, making it suited for specific tooling setups where conventional right-hand rotation is not appropriate. The head carries a Titanium Aluminum Nitride (TiAlN) coating, which improves wear resistance and tool life in ferrous and hardened materials. With a head diameter of 0.7500 inches and a head length of 0.4090 inches, this interchangeable head mounts onto compatible modular reamer bodies, allowing tooling flexibility across multiple bore sizes without replacing the entire tool assembly. Machinists and toolroom technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis modular reamer head is intended for precision reaming operations in machining environments, including CNC machining centers and manual mills where tight hole tolerances are required. The h7 hole tolerance classification designates it for close-clearance fits, common in bearing bores, hydraulic component ports, and precision assembly applications. It conforms to ISO 13399 tooling standards, supporting integration into tool management systems. Suitable for use in job shops, production machining facilities, and toolroom operations working with ferrous alloys, aluminum, and similar machinable materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.7500 inch head diameter with h7 hole tolerance for close-clearance precision fits\u003c\/li\u003e\n  \u003cli\u003eStraight flute geometry for controlled chip evacuation in through and blind hole reaming\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting direction for specialized tooling configurations\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for enhanced wear resistance and extended tool life in demanding materials\u003c\/li\u003e\n  \u003cli\u003eModular design mounts onto compatible reamer bodies for flexible tooling setups\u003c\/li\u003e\n  \u003cli\u003eISO 13399 compliant for compatibility with digital tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a modular replacement reamer head for use with compatible ISCAR modular reamer body systems accepting a 3\/4 inch head diameter in the h7 tolerance class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the reamer body and spindle are fully de-energized and the machine is in a locked-out state before mounting or removing the reamer head. Verify that mating surfaces on the reamer body are clean and free of chips or debris before torquing the head into position. Follow the tool manufacturer's assembly instructions for interface engagement to avoid damage to the modular connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.4090 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Tolerance\u003c\/strong\u003e: h7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Aluminum Nitride (TiAlN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 2.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2.24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5140143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51734827303218,"sku":"5140143","price":484.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b4edd8a082bee7c14a75e5751443f7a.jpg?v=1788767185","url":"https:\/\/voomisupply.com\/products\/iscar-5140143-modular-reamer-head-3-4-in-straight-flute-h7","provider":"Voomi Supply","version":"1.0","type":"link"}
