With a 3.2 mm (0.1260 inch) reamer diameter and a bright, uncoated finish, this tool delivers consistent bore sizing across a wide range of workpiece materials. The four-flute, straight-flute geometry provides smooth cutting action and accurate diameter control. It measures 57 mm in overall length with a 16 mm flute length, and features a straight cylindrical shank for secure chuck mounting. The right-hand cutting direction and tight diameter tolerance of plus 0.0001 to plus 0.0004 inches make it suitable for production and maintenance machining environments where hole quality and repeatability are critical.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for use in machine tool setups where a chucking reamer is mounted in a drill press, milling machine, or CNC machining center. It is sized within the 3.00 mm to 4.00 mm diameter range and is well suited for finish-reaming drilled or bored holes to close tolerances in metal components. Machinists and toolroom technicians in manufacturing, job shop, and MRO environments are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e3.2 mm (0.1260 inch) diameter with tolerance of plus 0.0001 to plus 0.0004 inches for precise bore finishing\u003c\/li\u003e\n\u003cli\u003eFour straight flutes for smooth, stable cutting performance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general machining applications\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for direct chuck clamping without adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard solid carbide chucking reamer for general machining applications within the 3.00 mm to 4.00 mm diameter range, part of the OSG 300D series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a drill chuck or collet before operation, and verify runout is within acceptable limits before cutting. Always bring the spindle to a complete stop before changing or inspecting the tool. Follow applicable shop safety procedures and machinery manufacturer guidelines for speeds and feeds appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 3.2 mm (0.1260 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 57 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 300D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 300-1260\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730794185010,"sku":"300-1260","price":55.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_1cf89c3f-7892-42b0-9534-22bb163aa224.jpg?v=1788722948","url":"https:\/\/voomisupply.com\/products\/osg-300-1260-chucking-reamer-3-2mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
