The reamer features 6 spiral flutes with a left-hand spiral geometry and right-hand cutting direction, a combination that reduces chatter and produces a smooth bore finish. Overall length is 117mm (4.61 inches) with a 33mm (1.30 inches) flute length. The bright, uncoated finish is suitable for use in a wide range of ferrous and non-ferrous materials. This tool is installed and operated by machinists and tool-and-die professionals in precision machining environments.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is used in CNC machining centers, knee mills, and drill presses where a straight-cylindrical shank is compatible with standard chuck toolholding. It is well suited for finishing holes in the 7.00mm to 8.00mm diameter range in production or maintenance machining operations. The straight-cylindrical shank allows quick changeover in collet chucks or drill chucks without specialized toolholding. Coolant-through is not supported, making it appropriate for conventional flood-coolant or dry-cutting setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7.92mm (0.3118 inches) finished diameter with +0.005mm tolerance for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction provides heat and wear resistance over high-speed steel\u003c\/li\u003e\n  \u003cli\u003e6 left-hand spiral flutes with right-hand cut reduce chatter and improve surface finish\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet toolholding\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating prep or recoating required\u003c\/li\u003e\n  \u003cli\u003e117mm (4.61 inches) OAL with 33mm (1.30 inches) flute length suits typical through-hole and shallow blind-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in machine tool spindles accepting a straight-cylindrical shank, compatible with applications requiring a finished hole diameter in the 7.00mm to 8.00mm range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis reamer is intended for use by trained machinists. Secure the straight-cylindrical shank firmly in a collet or drill chuck before operation, and ensure the spindle and workpiece are properly fixtured to prevent movement. Power down and lock out the machine before changing or inspecting the tool. Do not use this reamer as a drill — always pre-drill the hole to the appropriate undersize before reaming.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 7.92mm (0.3118 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 7.00mm to 8.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.005mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 117.00mm (4.61 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 33.00mm (1.30 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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.8 inches (L) x 0.51 inches (W) x 0.51 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5072872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51729638457650,"sku":"5072872","price":114.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7bd197fe31d79feabae08f5ab8291e6.jpg?v=1788707065","url":"https:\/\/voomisupply.com\/products\/walter-titex-5072872-chucking-reamer-7-92mm-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
