Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer features a 7\/8 inch diameter, a left hand spiral with right hand cut, and five flutes that produce a smooth, accurate bore. The 7-3\/8 inch flute length and 12 inch overall length give it reach for deep-hole applications. The No. 3 Morse taper shank seats directly into compatible drill presses, magnetic drills, and drill motors without a separate chuck.\u003c\/p\u003e\n\u003cp\u003eBridge reamers are standard tooling in structural steel shops, ironworking, and heavy equipment repair where bolt holes must be brought to precise diameter and alignment. This model is suited for reaming through multiple layers of steel plate or misaligned bolt holes on structural connections. The left hand spiral pushes chips down and out of the hole during right hand cutting, keeping the flutes clear in blind or deep-hole conditions. It is typically run at controlled spindle speeds with cutting fluid applied to the work surface to extend tool life and achieve proper hole finish.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8 inch diameter with 0.8750 inch decimal equivalent for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in structural steel and tough alloys\u003c\/li\u003e\n  \u003cli\u003eLeft hand spiral, right hand cut geometry clears chips away from the cutting zone\u003c\/li\u003e\n  \u003cli\u003eNo. 3 Morse taper (3MT) shank for direct mounting in compatible spindles and drill motors\u003c\/li\u003e\n  \u003cli\u003eFive flutes deliver a smooth bore finish and balanced cutting action\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — ready to use as delivered, accepts re-coating if needed after resharpening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling choice for drill presses, magnetic drills, and drill motors equipped with a No. 3 Morse taper (3MT) socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBridge reamers are installed and operated by machinists, ironworkers, and tool-and-die professionals. Before mounting, confirm the spindle or adapter accepts a No. 3 Morse taper and that the taper bore and shank are clean and free of chips or burrs. Power down and lock out the machine before seating or removing the shank. Apply cutting fluid to both the reamer and workpiece during operation, and never exceed the tool manufacturer's recommended spindle speed for the workpiece material.\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: 7\/8 inch (0.8750 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\u003eSmall End Diameter\u003c\/strong\u003e: 39\/64 inch\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 (No. 3 Morse Taper)\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 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: ST0730056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723213078834,"sku":"ST0730056","price":116.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e9230b0f4ed180ab569a1945f64ba38_76104e53-b804-4979-804a-735a5c93aa97.jpg?v=1788602009","url":"https:\/\/voomisupply.com\/products\/value-collection-st0730056-bridge-reamer-7-8-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
