Built from cobalt steel, this reamer delivers the hardness and heat resistance required for reaming ferrous and harder alloy materials. It features a 0.1230-inch diameter with a straight-cylindrical shank for secure chuck holding, a 7\/8-inch flute length, and a 3-1\/2-inch overall length. The bright, uncoated finish suits applications where coating buildup tolerance is tight. Right-hand cutting direction. Weighing 0.15 pounds, it is sized for precision work in drill press, lathe, or CNC setups.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for precision hole sizing and finishing in machine shop, toolroom, and production floor environments. It falls within the 0.1000 to 0.1499-inch reamer diameter range, making it appropriate for small-bore finish reaming in steel, cast iron, and similar materials. The straight-cylindrical shank allows it to seat directly in a standard drill chuck or collet holder. It is packaged individually and is a direct-use tooling item for machinists and tooling technicians working to close dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1230-inch reaming diameter for precision small-bore finishing\u003c\/li\u003e\n\u003cli\u003eCobalt steel construction for elevated heat resistance and hardness\u003c\/li\u003e\n\u003cli\u003eStraight flute design reduces cutting pressure in through-hole applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, bright uncoated finish\u003c\/li\u003e\n\u003cli\u003eDesignated as a dowel pin reamer for accurate pin-hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard drill press, lathe tailstock, or CNC machining center setups that accept straight-cylindrical shank tooling in the applicable diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with reaming operations. Ensure the workpiece and spindle are properly secured before operation, and confirm the shank is fully seated and clamped in the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Follow applicable shop safety procedures and machine manufacturer guidelines when setting spindle speed and feed rate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.1230 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.1000 to 0.1499 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: Yes\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: 72556129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736872747314,"sku":"72556129","price":47.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09858ac7a4699b50513997f6c7a95830_4bfcdb3d-cfb4-4b2a-8d13-a9ef041c71a5.jpg?v=1788781350","url":"https:\/\/voomisupply.com\/products\/hertel-72556129-chucking-reamer-0-1230-in-cobalt-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
