Built to Series 300D standards, it produces a diameter of 0.1040 inches with a tight tolerance of +0.0001 to +0.0004 inches, making it suitable for work requiring accurate, repeatable bore sizing. The reamer features a straight flute configuration with a right-hand cutting direction, a cylindrical straight shank for chuck mounting, and an uncoated bright finish. At 2.25 inches overall length with a 0.625-inch flute length, it fits compact work envelopes and close-tolerance setups common in precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for use in machining centers, drill presses, and CNC lathes where accurate final-pass hole sizing is required. Wire size 37 corresponds to a 0.1040-inch diameter, placing it in the smaller end of the decimal inch range for chucking reamers. It is well suited for ferrous and non-ferrous materials in production and job shop environments where dimensional accuracy and finish quality are critical. Licensed machinists and tooling specialists are the typical end users for this style of reamer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides hardness and wear resistance for consistent performance across production runs\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0001 to +0.0004 inches delivers precision bore sizing\u003c\/li\u003e\n\u003cli\u003eFour straight flutes with right-hand cut for clean material removal on finish passes\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains dimensional accuracy without coating buildup considerations\u003c\/li\u003e\n\u003cli\u003eCylindrical straight shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eSeries 300D designation for standard carbide general machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard carbide chucking reamer for general machining applications requiring wire size 37 (0.1040-inch) hole finishing with a straight shank chuck mount.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed by qualified machinists following the machine tool manufacturer guidelines for speed, feed, and fixturing. Always ensure the spindle and workpiece are properly secured before operation. Reamers should be used as a finish tool after a drill or boring operation has brought the hole to within a few thousandths of final size. Do not attempt to remove excessive stock with a reamer, as this will reduce tool life and compromise hole geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 37\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 inches\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: 300-1040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747336847666,"sku":"300-1040","price":51.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_aef981e0-d471-47d0-b2a7-7ac261c55f8e.jpg?v=1788878771","url":"https:\/\/voomisupply.com\/products\/osg-300-1040-chucking-reamer-size-37-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
