Built from high speed steel (HSS), this reamer features a spiral flute design with 5 flutes and measures 1 inch in diameter with a 1\/2 inch Morse taper shank. The 6.5 inch overall length provides the reach needed for bridge plate and structural connection work. HSS construction delivers the hardness and wear resistance required for repeated use in ferrous metals. This tool is installed by ironworkers, structural fabricators, and maintenance machinists working on bolted steel connections.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for structural steel fabrication, bridge construction, and heavy equipment maintenance where bolt holes must be aligned and finish-reamed to accept high-strength fasteners. The Morse taper shank allows direct mounting in drill presses, magnetic drills, and milling machines equipped with compatible taper-socket tooling. It is appropriate for both shop and field use on carbon steel and similar ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch reamer diameter for structural bolt-hole finishing\u003c\/li\u003e\n\u003cli\u003eSpiral flute geometry with 5 flutes for smooth chip evacuation and reduced chatter\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability in ferrous metal applications\u003c\/li\u003e\n\u003cli\u003e1\/2 inch Morse taper shank for positive tool retention in compatible holders\u003c\/li\u003e\n\u003cli\u003e6.5 inch overall length provides reach for deep or obstructed hole locations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, magnetic base drills, and milling machines fitted with a Morse taper tool holder.

Power down and fully de-energize the host machine before mounting or removing the reamer from the spindle. Secure the Morse taper shank firmly in the socket and verify there is no runout before commencing the cut. Use appropriate cutting fluid for ferrous metals and never exceed the recommended feed and speed parameters for HSS tooling in the material being reamed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\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: 6.5 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\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: 20997\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51721702179122,"sku":"20997","price":276.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_dcd9e4f8-1565-4bd9-a586-71d0c6c76167.jpg?v=1788579622","url":"https:\/\/voomisupply.com\/products\/import-20997-bridge-construction-reamer-1-in-hss-spiral","provider":"Voomi Supply","version":"1.0","type":"link"}
