Ford. 27203940 Chucking Reamer 1mm Solid Carbide","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.A. FORD. 27203940 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 1 mm (0.0394 inch) diameter and a 4-flute straight configuration, it delivers consistent, accurate results in close-tolerance bores. The straight shank allows direct mounting in standard chuck holders. At 1-1\/2 inches overall length with a 1\/4-inch flute length, this compact reamer suits small-diameter work where rigidity and concentricity are critical. The uncoated solid carbide construction handles hard and abrasive workpiece materials where high-speed steel tooling falls short. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for precision hole sizing in production machining, mold and die work, and instrument manufacturing where 1 mm bores require tight dimensional control. The right-hand spiral direction and right-hand cutting geometry are standard for conventional CNC and manual machine tool setups. Typical applications include finishing pre-drilled or bored holes to achieve H7 or similarly close fits in steel, aluminum, brass, and other machinable materials. No coolant-through capability means it is best applied with external flood or mist coolant delivery where chip evacuation allows.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 mm (0.0394 inch) diameter with tolerance of +0.004\/+0.008 mm for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003e4-flute straight configuration promotes smooth cutting action and consistent surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral geometry compatible with standard CNC and manual setups\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard chuck holders without special tooling adapters\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications where coating compatibility with workpiece material is a concern\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision chucking reamer for use in standard straight-shank chuck holders on CNC machining centers, drill presses, and manual mills or lathes configured for small-diameter reaming operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the straight shank firmly in a precision collet or drill chuck and verify runout before operation. Power down the machine spindle completely before changing or setting tooling. Apply adequate external coolant or cutting fluid during operation to manage chip evacuation and tool temperature, as this reamer does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1.00 mm (0.0394 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (38.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1\/4 inch (6.50 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\u003eSpiral Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.004\/+0.008 mm\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: 272\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 27203940\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51730965823794,"sku":"27203940","price":49.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84a8cc15933969e074f42bdf876353c1.jpg?v=1788725404","url":"https:\/\/voomisupply.com\/products\/m-a-ford-27203940-chucking-reamer-1mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
