Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer maintains sharp cutting edges across a range of ferrous and non-ferrous materials. The 4-flute straight-flute geometry provides consistent chip evacuation and smooth bore finishes in through-hole and blind-hole applications. The straight-cylindrical shank seats directly in a drill chuck or collet, making setup fast and repeatable. It is a standard stock item for machinists, tool-and-die makers, and maintenance technicians who need reliable hole-finishing at small diameters.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for small-diameter finish reaming in manual mills, drill presses, CNC machining centers, and lathes. It covers applications in light manufacturing, maintenance and repair operations (MRO), and toolroom work where tight hole tolerances are required. The 0.0850-inch diameter falls within the 0.0500 to 0.0999-inch decimal inch range, making it appropriate for small precision bores in fixtures, dies, and machine components. Right-hand cutting direction is standard for conventional spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0850-inch reamer diameter for precise small-bore finishing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute design promotes smooth finish and consistent chip clearance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose reaming without added coating cost\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for use with conventional spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose chucking reamer for use in drill presses, manual mills, CNC machining centers, and lathes equipped with standard drill chucks or collet systems accepting a straight-cylindrical shank at this diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers should be installed by a qualified machinist or toolroom technician. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation, and verify runout before cutting. Always ream at reduced spindle speeds compared to drilling, and apply appropriate cutting fluid for the workpiece material. Never use a reamer to remove excessive stock — drill or bore the hole to within a few thousandths of final size before reaming.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.0850 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.0500 to 0.0999 inches (decimal inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SM0400850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701121483058,"sku":"SM0400850","price":19.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba8491fd0391f09af4d63d7832bafa18.jpg?v=1788398454","url":"https:\/\/voomisupply.com\/products\/value-collection-sm0400850-chucking-reamer-0-085-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
