Sized to wire gauge No. 56, it machines holes to a decimal diameter of 0.0465 inches. Constructed from high-speed steel (HSS) with a bright, uncoated finish, the reamer delivers consistent cutting performance across ferrous and non-ferrous materials. The straight-cylindrical shank seats directly in a standard drill chuck or collet. Four right-hand flutes provide smooth stock removal and accurate hole sizing in production and maintenance machining applications. Overall length is 2.5 inches with a flute length of 0.5 inches.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for machine shop production, toolroom work, and maintenance machining where small-diameter holes require close-tolerance finishing. The wire gauge No. 56 size addresses applications in instrument work, light manufacturing, and precision assembly where standard fractional or letter-size reamers are too large. It is intended for use in a drill press, mill, or lathe with appropriate work-holding and feeds appropriate to HSS tooling in small diameters. Licensed machinists and tool-and-die professionals are the primary installers and operators.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 56 diameter (0.0465 inches decimal) for precision small-hole finishing\u003c\/li\u003e\n\u003cli\u003eHSS construction provides good wear resistance across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish allows direct visual inspection of cutting edges\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without adaptation\u003c\/li\u003e\n\u003cli\u003eFour straight flutes, right-hand cutting, for smooth and accurate stock removal\u003c\/li\u003e\n\u003cli\u003eCompact 2.5-inch OAL suits short-reach setups and close-tolerance work-holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, milling machines, and lathes equipped with a drill chuck or collet capable of holding a straight-cylindrical shank in the applicable diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePower down and lock out the machine before mounting or removing the reamer from the chuck or collet. Secure the workpiece firmly before cutting to prevent movement that can break small-diameter tooling. Use cutting fluid appropriate for the workpiece material and maintain recommended feeds and speeds for HSS tooling at this diameter range. Inspect cutting edges before each use; discard or resharpen if chipping or wear is visible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Gauge)\u003c\/strong\u003e: No. 56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0465 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\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\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: 2291565\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732759511346,"sku":"2291565","price":48.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a40272d09b39da88529778c4e9675c6b_cfa41ad9-bf66-4047-931b-d74d47f0ab2d.jpg?v=1788746402","url":"https:\/\/voomisupply.com\/products\/hertel-2291565-chucking-reamer-size-56-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
