With a nominal diameter of 0.2765 inches and a 6-inch overall length, this reamer provides the extended reach needed for production and jobshop applications. The straight flute geometry and bright uncoated finish make it well-suited for reaming softer materials including aluminum, brass, and mild steel. It is installed by machinists and toolroom technicians operating drill presses, lathes, CNC machining centers, and manual mills.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is used in general metalworking environments where hole-finishing to close dimensional tolerances is required. The straight-cylindrical shank allows direct chucking in standard drill chucks or collet holders without additional adapters. With a 1.5-inch flute length and right-hand cutting direction, it is appropriate for through-holes and shallow blind holes in light to medium production runs. It is a single-unit tool suited to prototype work, maintenance machining, and repetitive production fixturing alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2765-inch reamer diameter for precise hole finishing in the 0.2500 to 0.2999-inch diameter range\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides clearance in deeper workpiece setups\u003c\/li\u003e\n\u003cli\u003e6-flute straight configuration delivers smooth cutting action and good chip clearance in soft to medium-hardness materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct mounting in standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish on HSS substrate  -  no coating to chip or flake during re-sharpening\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, compatible with conventional spindle rotation\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 chucks and collet holders accepting straight-cylindrical shanks across drill presses, lathes, and machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers should be installed by qualified machinists following established shop safety procedures. Always power down and lock out the spindle before mounting or removing the tool from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole-finish quality. Never force a reamer into an undersized hole  -  pre-drill or bore to within a few thousandths of the finish diameter before reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2765 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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\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: 72027659\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51972012245298,"sku":"72027659","price":68.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_7ed663ec-93a0-4eb4-bd13-deb42a54d8b6.jpg?v=1789960944","url":"https:\/\/voomisupply.com\/products\/hertel-72027659-chucking-reamer-0-2765-in-hss-straight-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
