With a 0.250 inch (Letter E) cutting diameter, 4 straight flutes, and an uncoated solid carbide construction, this reamer delivers accurate, repeatable sizing in ferrous and non-ferrous materials. The straight shank allows direct mounting in drill chucks or collets on manual lathes, CNC turning centers, and milling machines. Machinists and toolroom technicians use this reamer where tight tolerance bores are required and drill-quality holes are not acceptable. Overall length is 3 inches with a 1 inch flute length.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for light-to-medium stock removal in through-holes and blind holes where a finished bore diameter of 0.250 inch is required. Typical applications include fixture and jig work, bearing seat preparation, and close-tolerance pin or dowel fits. The solid carbide body maintains rigidity at higher speeds compared to high-speed steel alternatives, making it appropriate for production environments and short-run precision work alike. It is sold individually and does not require special adapters beyond a standard straight-shank chuck or collet of the appropriate bore size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding machining environments\u003c\/li\u003e\n  \u003cli\u003e0.250 inch cutting diameter, also designated Letter E, for precise bore sizing\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes provide clean chip evacuation and consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eStraight shank for direct mounting in drill chucks, ER collets, or collet chucks\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with standard cutting fluids across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCompact 3 inch overall length with 1 inch flute length for short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use chucking reamer for standard straight-shank toolholders accepting a 0.250 inch shank diameter.

Always secure the straight shank fully within the collet or chuck jaws before operation, and verify runout with a dial indicator where tolerance is critical. Power down and lock out the machine spindle before changing tooling. Apply an appropriate cutting fluid for the workpiece material to extend tool life and achieve the target surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.250 inch (1\/4 inch, Letter E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 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\u003eShank Type\u003c\/strong\u003e: Straight\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: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC87311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51753848537394,"sku":"TC87311","price":92.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a06e28f63151d52c59d0c41dd7f60a44_55711f37-fdb8-469e-8111-47aaca79418e.jpg?v=1788941454","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc87311-chucking-reamer-1-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
