Built from cobalt steel with a bright, uncoated finish, it delivers the heat and wear resistance needed for reaming harder ferrous and exotic alloy workpieces. The straight flute geometry and right-hand cutting direction are standard for general-purpose through-hole reaming on drill presses, lathes, and CNC machining centers. Four flutes provide a balance of chip clearance and surface finish quality. The straight-cylindrical shank seats directly in standard drill chucks or collet holders without adapters, making tool changes straightforward in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for precision hole finishing in metalworking applications where wire-gauge tolerances are required. With an overall length of 2.5 inches and a flute length of 0.5 inches, it is sized for shallow reaming passes in small-diameter through holes. Machinists, tool-and-die makers, and maintenance technicians working on small-bore components such as bushings, dowel pin holes, and instrument housings will find this size range common in their work. It is not designed as a dowel pin reamer and is not an over- or under-size variant.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire-gauge No. 54 diameter: 0.0550 inches, within the 0.0500 to 0.0999 inch decimal range\u003c\/li\u003e\n\u003cli\u003eCobalt steel construction for improved heat resistance over standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — ready to use as supplied or compatible with post-treatment coatings\u003c\/li\u003e\n\u003cli\u003e4-flute straight geometry balances chip evacuation with bore surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets with no adapter required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in any machine tool setup accepting a straight-cylindrical shank of equivalent diameter, including drill presses, engine lathes, turret lathes, and CNC machining centers performing small-bore hole finishing operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and removed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing tooling. Secure the straight-cylindrical shank firmly in the chuck or collet to the tool-holder manufacturer's specified clamping torque range. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore tolerance. Never use a reamer to remove more stock than recommended for the diameter class — pre-drill or bore to within a few thousandths of finished size before reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: No. 54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.0500 to 0.0999 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 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-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: 72308547\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748195303730,"sku":"72308547","price":54.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09858ac7a4699b50513997f6c7a95830_967955f9-5ba9-4bc4-98b7-42c2c9aa1d6f.jpg?v=1788890189","url":"https:\/\/voomisupply.com\/products\/hertel-72308547-chucking-reamer-size-54-cobalt-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
