Constructed from high-speed steel with a bright uncoated finish, this reamer delivers consistent sizing and surface finish in a wide range of metals and engineering materials. The 6-flute configuration distributes cutting load evenly, reducing chatter and improving hole roundness. With a 2-1\/4-inch flute length and 4-1\/2-inch overall length, the tool is well suited for through-holes and blind holes in light- to medium-duty production and maintenance work. Machinists and tool-and-die tradespeople reach for hand reamers at the bench vise or in hand-held drill drivers when tight tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThis hand reamer is intended for manual or low-speed machine reaming operations where controlled stock removal and accurate final bore size are the priority. The straight shank seats directly in a tap wrench, chuck, or reamer driver. Typical applications include sizing holes in fittings, brackets, and machined components in HVAC fabrication shops, plumbing prefab operations, and general metalworking environments. The right-hand cutting direction is standard for conventional clockwise rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch reamer diameter for precise hole sizing to 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e6 straight flutes distribute cutting load evenly to reduce chatter\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows visual inspection of cutting edges\u003c\/li\u003e\n  \u003cli\u003eStraight shank compatible with standard tap wrenches and drill chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for conventional clockwise operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hand reamer replacement for use in standard tap wrenches, chuck-mounted drivers, and bench reaming setups requiring a 5\/16-inch finished bore diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHand reamers are installed and operated by machinists or qualified tradespeople familiar with cutting tool safety. Secure the workpiece firmly before reaming and apply a suitable cutting fluid to extend tool life and improve surface finish. Always rotate in the cutting direction only — reversing rotation under load will damage the flute edges. Follow applicable shop safety standards for eye protection and chip management when working with metal-cutting tools.\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\u003eFlute Length\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 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\u003eShank 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\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: SM1900020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720929640754,"sku":"SM1900020","price":38.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9384ea7a0f2adb5db46ee34b49d72ccc.jpg?v=1788571096","url":"https:\/\/voomisupply.com\/products\/value-collection-sm1900020-hand-reamer-5-16-in-6-flutes-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
