Built from high speed steel (HSS), it delivers the hardness and heat resistance needed for demanding metal removal tasks. The 5\/8-inch cutting diameter and 1\/2-inch Morse taper shank give it a stable, concentric grip in compatible taper-socket spindles. Five spiral flutes clear chips efficiently and reduce chatter during the reaming pass. Overall length is 5 inches. Licensed machinists, ironworkers, and fabricators working on structural connections rely on this style of reamer for bolt-hole alignment and finishing on bridge and heavy construction assemblies.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for structural steel fabrication, bridge construction, and heavy ironwork where pre-drilled bolt holes require finishing or alignment correction. The spiral flute geometry makes it effective in through-hole applications with consistent chip evacuation. It is a single-piece, solid HSS tool used in drill press, mill, or hand-reaming setups with a Morse taper adapter. Typical applications include beam splice plates, gusset connections, and erection bolt holes where dimensional accuracy is critical to structural fit-up.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-inch cutting diameter for standard structural bolt-hole finishing\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction resists heat buildup during extended reaming passes\u003c\/li\u003e\n\u003cli\u003e5-flute spiral design promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e1\/2-inch Morse taper shank provides secure, concentric seating in taper-socket toolholders\u003c\/li\u003e\n\u003cli\u003e5-inch overall length suits typical structural steel thickness ranges\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use bridge-construction reamer compatible with Morse taper spindle toolholders accepting a 1\/2-inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall the Morse taper shank securely into a compatible taper socket on a drill press, mag drill, or milling machine spindle before use. Power down the machine and ensure the workpiece is firmly clamped before engaging the reamer. Apply cutting fluid appropriate for steel to extend tool life and maintain hole finish quality. This tool is intended for use by trained machinists or qualified ironworkers following applicable shop safety procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Morse Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20994\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51691444633906,"sku":"20994","price":150.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ae40047e9a161e3eb46f231cc2cc9f1.jpg?v=1788285118","url":"https:\/\/voomisupply.com\/products\/import-20994-bridge-construction-reamer-5-8-in-hss-spiral","provider":"Voomi Supply","version":"1.0","type":"link"}
