Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and smooth bore finish in a range of common workpiece materials. The straight-cylindrical shank seats securely in standard chuck holders, and the right-hand cutting direction is compatible with conventional drilling setups. With an overall length of 6 inches and a 1.5-inch flute length, this reamer suits general-purpose machine shop and maintenance applications where close-tolerance hole finishing is required.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for use in vertical mills, drill presses, lathes, and CNC machining centers performing finish-reaming operations on ferrous and non-ferrous materials. It is a practical choice for toolroom work, fixture building, and production runs requiring repeatable hole sizing in the 0.2500 to 0.2999-inch diameter range. Machinists and maintenance technicians install it wherever a drilled or bored pilot hole needs to be brought to final tolerance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2750-inch reamer diameter for precise finish-bore sizing\u003c\/li\u003e\n\u003cli\u003e6-flute straight design promotes smooth cutting and accurate hole geometry\u003c\/li\u003e\n\u003cli\u003eHSS construction provides toughness and wear resistance across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for straightforward chuck mounting\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in any machine tool equipped with a drill chuck or collet that accepts a straight-cylindrical shank; fits applications requiring finish reaming in the 0.2500 to 0.2999-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this reamer should be performed by a qualified machinist or maintenance technician familiar with machine tool operation. Always secure the workpiece and verify the machine is at a safe, reduced RPM appropriate for reaming before starting the cut. Apply cutting fluid to extend tool life and improve surface finish. Never force the reamer through an undersized pilot hole; ensure the pilot bore is properly sized before finish-reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: HSS (High-Speed 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: 72027501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728441213234,"sku":"72027501","price":66.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_219e9379-fc82-4e56-a1ff-769d5400dfe0.jpg?v=1788691237","url":"https:\/\/voomisupply.com\/products\/hertel-72027501-chucking-reamer-0-2750-in-hss-straight-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
