Built from high-speed steel (HSS) with a bright uncoated finish, this reamer produces accurate, smooth bores at wire size 52, corresponding to a decimal diameter of 0.0635 inches. The straight 4-flute geometry and right-hand cutting direction deliver consistent material removal in drill press, lathe, and CNC applications. At 1-7\/8 inches overall length with a 1\/2-inch flute length, this is a compact tool suited for shallow, tight-tolerance reaming operations in small-diameter bores.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for use in machine tool setups where the workpiece or tool is held in a chuck or collet. It is well suited for general machining environments including job shops, tool rooms, and production lines working with ferrous and non-ferrous metals. The straight-cylindrical shank seats securely in standard chucks and collets, making setup straightforward for machinists and tool-and-die professionals. It is typically used as a finishing step after drilling to bring a hole to final size and surface quality.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 52 diameter — 0.0635 inches decimal equivalent for precise small-bore finishing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of metals\u003c\/li\u003e\n\u003cli\u003e4-flute straight geometry for stable, consistent cutting action\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction — standard for most machine tool setups\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for compatibility with standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup concerns in sensitive tolerance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in machine tool setups requiring wire size 52 hole finishing with a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed by machinists in lathes, drill presses, or CNC machining centers. Secure the straight-cylindrical shank firmly in a chuck or collet before use and ensure the workpiece is clamped. Always bring the hole to near-final size by drilling before reaming — do not use this tool as a primary hole-making cutter. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0635 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches (2.0000 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1\/2 inch\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: 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: 0.1 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: 72290521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728801104178,"sku":"72290521","price":35.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fde7dad717d2d818e16cebf163b35705_f985adee-ac4d-4107-a227-b6dce32544e6.jpg?v=1788696278","url":"https:\/\/voomisupply.com\/products\/hertel-72290521-chucking-reamer-size-52-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
