Machined from cobalt steel with a bright, uncoated finish, it delivers the hardness and heat resistance needed for interrupted cuts and tougher workpiece materials. The straight-cylindrical shank mounts directly in a drill chuck or collet. With a 5-inch overall length and a 1.25-inch straight flute section, this reamer suits bench drill presses, knee mills, and CNC drilling centers where consistent hole tolerance is the priority. Right-hand cutting direction is standard for conventional clockwise-spindle operation.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for production and job-shop machining applications requiring close-tolerance hole finishing in the 0.1500-to-0.1999-inch decimal range. Typical use cases include reaming holes in steel, cast iron, aluminum, and similar machinable materials where a drilled hole must be brought to a controlled final diameter. It is sized for operations that do not require oversized or undersized reaming, and it is not a dowel pin reamer. Machinists and tool-and-die professionals are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction resists heat buildup during extended reaming operations\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish allows direct visual inspection of cutting edges\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and ER collet systems\u003c\/li\u003e\n\u003cli\u003eStraight flute geometry provides clean entry and chip clearance in through-holes\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with conventional spindle rotation\u003c\/li\u003e\n\u003cli\u003eWire Size 8 at 0.1990 inches covers the upper range of the 0.1500-to-0.1999-inch diameter class\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use chucking reamer for machine tool setups requiring a Wire Size 8 straight-flute reamer with a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified toolroom technician should install and operate this reamer. Power down and lock out the spindle before seating or removing the shank from the chuck or collet. Use cutting fluid appropriate for the workpiece material to extend tool life and maintain hole finish. Follow shop safety standards and applicable OSHA machining guidelines when operating rotating cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1990 inches\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\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\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-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: 72308083\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730502320434,"sku":"72308083","price":41.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72e2e18333df4a003c3e2e1b8f028578_82423964-7130-48c8-b257-b87eaca07c43.jpg?v=1788718594","url":"https:\/\/voomisupply.com\/products\/hertel-72308083-chucking-reamer-wire-8-cobalt-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
