With a reamer diameter of 0.186 inches and a four-flute straight flute geometry, it delivers tight tolerances and smooth surface finishes in through-holes and blind holes alike. The straight shank mounts directly in a drill chuck or collet holder on a milling machine, drill press, or lathe. A bright polished finish reduces friction and helps with chip evacuation. Machinists and tool-and-die professionals use this reamer when a drilled hole requires accurate sizing to a close tolerance for pin or dowel fits.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for use in job shops, production machining, and maintenance repair environments where consistent hole quality is required. The 0.186-inch diameter falls within the 0.1500 to 0.1999 inch decimal range, making it appropriate for small-hole finishing operations in steel, cast iron, aluminum, and similar materials. The overall length of 2.75 inches and a flute length of 0.875 inches allow it to reach through standard workpiece thicknesses without excessive tool overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eFour straight flutes with right-hand cutting direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright polished finish to reduce built-up edge and improve chip flow\u003c\/li\u003e\n\u003cli\u003eStraight shank for direct mounting in a drill chuck or collet holder\u003c\/li\u003e\n\u003cli\u003e0.186-inch diameter for close-tolerance hole sizing in the 0.15 to 0.1999 inch range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, milling machines, lathes, and CNC machining centers that accept a straight-shank tooling with appropriate chuck or collet capacity for the 0.186-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified toolroom technician should install and operate this reamer. Ensure the machine spindle is fully stopped and the toolholder is properly seated and tightened before starting the cut. Use the correct cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Do not use this reamer to remove excessive stock; drill the hole to within a few thousandths of final size before reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.186 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.1500 to 0.1999 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 45675048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":52090684014898,"sku":"45675048","price":99.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/727ad9bf6b7cb8e2d95e4e65dedd7c6c.jpg?v=1790062646","url":"https:\/\/voomisupply.com\/products\/hertel-45675048-chucking-reamer-0-186-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
