Ford. 27231250 Chucking Reamer 5\/16 Inch Solid Carbide","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe M.A. FORD. 27231250 is a solid carbide chucking reamer designed to finish-ream drilled or bored holes to precise tolerances. With a 5\/16-inch (0.3125 inch) diameter and a tolerance of +0.0001 to +0.0003 inches, this reamer delivers the tight dimensional accuracy required in precision machining, toolroom work, and production environments. The 6-flute straight geometry promotes smooth, consistent cutting action on through-holes and blind holes alike. The straight shank seats directly into standard drill chucks or collet holders. It is installed by machinists and tool-and-die professionals on CNC machining centers, manual mills, and drill presses.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for finishing operations in metals where hole-size accuracy and surface finish are critical. Its uncoated solid carbide construction performs well in non-ferrous metals, cast iron, and other materials where carbide tooling is preferred over high-speed steel. The compact 3-1\/4-inch overall length keeps the tool rigid in setups with limited Z-axis clearance. It is appropriate for both low-volume toolroom applications and higher-volume production runs requiring repeatable hole geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance versus high-speed steel reamers\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0001 to +0.0003 inches delivers close-tolerance hole finishing\u003c\/li\u003e\n  \u003cli\u003e6-flute straight configuration for consistent surface finish and smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, straight shank for direct chuck or collet mounting\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no coating thickness variation affecting final hole diameter\u003c\/li\u003e\n  \u003cli\u003eCompact 3-1\/4-inch OAL with 1-1\/8-inch flute length suited to short-reach setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard drill chucks and collet holders accepting a straight shank in the 5\/16-inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers should be installed by qualified machinists following proper workholding and spindle-alignment procedures. Ensure the workpiece is securely fixtured and the spindle is aligned to the hole axis before reaming to prevent bell-mouthing or chatter. Cutting fluid or coolant appropriate for the workpiece material should be applied to extend tool life and improve surface finish. Never use a reamer to remove excessive stock — drill or bore the hole to within standard reaming allowance before finishing with this tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.3000 to 0.3499 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0001 \/ +0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-1\/4 inches (3.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\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\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 27231250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51727478358322,"sku":"27231250","price":109.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3bcb67d50664bb5596c0eadb4fa9e25.jpg?v=1788678357","url":"https:\/\/voomisupply.com\/products\/m-a-ford-27231250-chucking-reamer-5-16-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
