With a 5\/16 inch diameter tip and an overall length of 6 inches, this reamer is sized for common bore finishing tasks where dimensional accuracy and surface finish matter. HSS construction provides the hardness and wear resistance needed for reaming ferrous and non-ferrous materials. Machinists and tool-and-die professionals rely on this style of reamer to bring drilled holes to final tolerance.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for use in drill presses, lathes, and CNC machining centers where a chuck-held tool is required. The straight flute geometry makes it appropriate for through-holes and shorter blind-hole applications in a shop or field machining environment. It is sold individually and is a standard fit for general metalworking, maintenance repair, and precision assembly operations requiring a finished 5\/16 inch bore.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for hardness and wear resistance across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight flute design suited for through-hole and short blind-hole reaming\u003c\/li\u003e\n\u003cli\u003e5\/16 inch diameter tip for standard bore finishing to close tolerance\u003c\/li\u003e\n\u003cli\u003e6 inch overall length accommodates chuck-held setups in drill presses, lathes, and machining centers\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.05 pounds — easy to handle and tool-change quickly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in any machine tool capable of holding a straight-shank tool, including drill presses, engine lathes, and CNC machining centers requiring a 5\/16 inch finished bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers should be installed by a qualified machinist or tooling technician. Ensure the spindle and workpiece are secured before operation, and always use appropriate cutting fluid for the material being reamed to extend tool life and achieve the desired surface finish. Never use a chucking reamer to remove excessive stock — pre-drill or bore the hole to within a few thousandths of final diameter before reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 5\/16 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 Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 698464072130\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5010640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51344708010290,"sku":"5010640","price":33.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538589.jpg?v=1782041104","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5010640-hss-chucking-reamer-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
