Built to wire size 27 (0.1440 inches diameter), this reamer holds a tolerance of +0.0002 to 0.0000 inches, making it suitable for work where final bore size is critical. The AlTiN coating extends tool life in hard and abrasive materials. With a 3-inch overall length and a straight-cylindrical shank measuring 0.1875 inches in diameter, it seats securely in standard chucks and collets used on CNC mills, drill presses, and manual lathes. Four straight flutes in a right-hand cutting direction provide smooth, consistent stock removal on the finishing pass.\u003c\/p\u003e\u003cp\u003eThis reamer is part of the Miniature Reamers series, intended for small-diameter holemaking and threading applications in precision machining environments. It is well suited for toolrooms, production shops, and maintenance operations that require repeatable hole geometry in metal components. The 3\/4-inch flute length concentrates the cutting action close to the tip, which is appropriate for shallow through-holes and blind-hole finishing at this diameter range. Machinists working with small-bore hydraulic fittings, instrument housings, and precision assemblies will find this reamer addresses the accuracy demands of those applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 27 diameter: 0.1440 inches with a tight tolerance of +0.0002 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends cutting life\u003c\/li\u003e\n\u003cli\u003e4 straight flutes, right-hand cut, for clean and consistent bore finishing\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank (0.1875 inches) for direct chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eMiniature series design optimized for small-diameter precision holemaking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for small-diameter chucking reamer applications in the miniature reamers product category.

Secure the shank fully in a collet or drill chuck rated for the spindle speed appropriate to the workpiece material and reamer diameter before starting the cut. Always bring the machine to a complete stop before changing or inspecting tooling. Use appropriate cutting fluid or coolant where the machine setup permits to support surface finish and tool life, noting that this reamer does not feature through-coolant capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.1440 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: +0.0002 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature Reamers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RSB1440-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731894599986,"sku":"RSB1440-C3","price":80.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b21a35b19ea3ae3711f814292264c786_1cc1b46c-aa17-44d4-9ba4-c1c14e91a5b5.jpg?v=1788736198","url":"https:\/\/voomisupply.com\/products\/harvey-tool-rsb1440-c3-chucking-reamer-0-1440-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
