Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent material removal in demanding shop and field applications. The reamer measures 3\/4 inches in diameter with a 7-3\/8 inches flute length and a 12 inches overall length. A left-hand spiral, right-hand cut configuration reduces the tendency to pull the tool into the workpiece, giving the operator better control during through-hole finishing. It is installed and operated by machinists, ironworkers, and structural fabricators.\u003c\/p\u003e\n\u003cp\u003eBridge reamers are a standard tool in structural steel fabrication and erection, used to bring misaligned bolt holes into true alignment before fastener installation. This model is suited for use in both manual and machine setups. The 3 Morse Taper (3MT) shank connects directly to compatible drill presses, magnetic drills, and manual reaming handles without adapters on machines with a native MT3 spindle. The small end diameter of 15\/32 inches provides the entry lead-in geometry characteristic of bridge-style reamers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inches finished hole diameter with 15\/32 inches small end for guided entry\u003c\/li\u003e\n  \u003cli\u003e7-3\/8 inches spiral flute length for deep reach in thick structural members\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral, right-hand cut reduces tool pull and improves chip control\u003c\/li\u003e\n  \u003cli\u003e5-flute geometry distributes cutting load and produces a smoother bore finish\u003c\/li\u003e\n  \u003cli\u003e3 Morse Taper (3MT) shank for secure, self-holding connection in compatible spindles\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright uncoated finish suitable for general steel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, magnetic base drills, and reaming fixtures equipped with a 3 Morse Taper (3MT) spindle.

Apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Operate at reduced spindle speeds compared to twist drilling — bridge reamers require lower RPM and steady feed pressure. Inspect the flutes and cutting edges for chipping or wear before each use, and never use a damaged reamer in a structural application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Type\u003c\/strong\u003e: Bridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 15\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\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: Morse Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 3MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\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: 1.37 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: ST0730048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718282641714,"sku":"ST0730048","price":104.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95cca04ec242b529611f18cf928c1bb6.jpg?v=1788551572","url":"https:\/\/voomisupply.com\/products\/value-collection-st0730048-bridge-reamer-3-4-in-hss-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
