Built from high-speed steel with a bright, uncoated finish, it features a 1-3\/8 inch diameter cutting head and a 4MT Morse taper shank for secure seating in taper-socket spindles. The left-hand spiral, right-hand cut geometry produces a smooth finish while controlling chip flow away from the cutting edge. With five flutes and a 7-3\/8 inch flute length, it handles deep through-holes with consistent stock removal. Ironworkers, structural fabricators, and millwrights are the primary users for this tool.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for structural steel erection, heavy equipment fabrication, and bridge or frame assembly work where bolt holes must be brought into alignment before fastener installation. The 4MT shank mounts directly in magnetic drill presses, drill press quills, and heavy-duty portable rigs equipped with a matching Morse taper socket. The 1-1\/8 inch small end diameter allows entry into undersized or misaligned holes before full-diameter engagement. It is intended for use on steel and similar ferrous materials where precise hole sizing and alignment are critical to structural integrity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8 inch cutting diameter with 1-1\/8 inch small end for guided entry into misaligned holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability and heat resistance during heavy-feed reaming\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral, right-hand cut geometry controls chip evacuation and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eFive flutes deliver a consistent finish and even cutting load across the hole wall\u003c\/li\u003e\n  \u003cli\u003e4MT Morse taper shank seats securely in compatible drill press and portable drill spindles\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains dimensional accuracy without coating buildup\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 portable drilling equipment fitted with a No. 4 Morse taper socket.

Secure the Morse taper shank fully into the spindle socket and verify it is seated and locked before operation. Power down and de-energize the drill before mounting or removing the reamer. Use cutting oil or a suitable metalworking fluid to extend tool life and maintain surface finish quality.\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: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1-1\/8 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: 3.7 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: ST0740124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690750607666,"sku":"ST0740124","price":242.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e9230b0f4ed180ab569a1945f64ba38.jpg?v=1788274960","url":"https:\/\/voomisupply.com\/products\/value-collection-st0740124-bridge-reamer-1-3-8-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
