Built from high-speed steel with a bright uncoated finish, it delivers reliable cutting performance in ferrous and non-ferrous materials. The reamer measures 1-5\/16 inches in diameter with a 7-3\/8 inches flute length and a 13 inches overall length. A No. 4 Morse Taper shank seats securely in compatible machine spindles, and the five-flute spiral configuration provides stable material removal. Licensed machinists and ironworkers use this tool in bridge fabrication, structural steel erection, and heavy equipment maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis bridge reamer is suited for through-hole alignment work where bolt holes in mating structural members must be brought to final size and concentricity. The left-hand spiral flute geometry pulls chips away from the cutting edge on a right-hand cut, reducing chip packing in deep holes. It is commonly used in field and shop operations involving structural steel connections, gusset plates, and heavy fabricated weldments where precise hole sizing is required before fastener installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-5\/16 inches cutting diameter with 1-1\/64 inches small end diameter for gradual lead-in\u003c\/li\u003e\n  \u003cli\u003e7-3\/8 inches spiral flute length accommodates material stack thickness common in structural work\u003c\/li\u003e\n  \u003cli\u003eFive-flute design distributes cutting load and improves surface finish inside the bore\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral with right-hand cut evacuates chips away from the cutting zone\u003c\/li\u003e\n  \u003cli\u003eNo. 4 Morse Taper shank for positive drive in drill presses, magnetic drills, and machine spindles\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright uncoated finish for general-purpose use across common metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any machine spindle or portable magnetic drill accepting a No. 4 Morse Taper shank.

Secure the Morse Taper shank fully into the spindle socket before operation and confirm the drift slot is accessible for removal. Always reduce spindle speed relative to a standard twist drill of the same diameter when reaming, and apply cutting fluid appropriate for the workpiece material. Never attempt to ream a hole more than a small fractional increment larger than the drilled pilot diameter in a single pass.\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\u003eCutting Diameter\u003c\/strong\u003e: 1-5\/16 inches (1.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1-1\/64 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: 13 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: 4MT\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: 3.85 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: ST07S0120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698796298546,"sku":"ST07S0120","price":222.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/841349310c697440be7853beac3001ea.jpg?v=1788368070","url":"https:\/\/voomisupply.com\/products\/value-collection-st07s0120-bridge-reamer-1-5-16-in-hss-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
