Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent bore sizing in a wide range of ferrous and non-ferrous materials. It features a 0.3475-inch diameter, six flutes, and a straight-cylindrical shank for secure chuck retention. With a 6-inch overall length and a 1.5-inch flute length, it is sized for bench-top lathes, drill presses, and CNC turning centers. Right-hand cutting direction is standard. This tool is typically installed and operated by machinists and tool-and-die professionals working to close dimensional tolerances.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for production and maintenance machining environments requiring repeatable bore finishing. The 0.3475-inch nominal diameter places it within the 0.3000 to 0.3499 inch reamer diameter range, making it appropriate for sizing holes to near-finished or finished bore specifications. It is commonly used in job shops, manufacturing facilities, and maintenance repair operations where HSS tooling is preferred for its toughness and regrindability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.3475-inch cutting diameter for precision bore finishing\u003c\/li\u003e\n\u003cli\u003eSix straight flutes for smooth, consistent stock removal\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability and regrindability\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup affecting dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, standard for most machine setups\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 systems accepting a straight-cylindrical shank.

Secure the shank firmly in the chuck or collet before operation and verify runout before engaging the workpiece. Always reduce spindle speed significantly compared to drilling — reaming typically requires one-third to one-half of the drilling speed for the material. Power down and lock out the machine before changing or inspecting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.3475 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.3000 to 0.3499 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: 8272387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733956002098,"sku":"8272387","price":67.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e222dc0262bb90a42d7d2294d51da27_66c2fbae-7fd8-47e6-a8ac-1dd560d80aa4.jpg?v=1788760173","url":"https:\/\/voomisupply.com\/products\/hertel-8272387-chucking-reamer-0-3475-in-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
