It features a spiral flute geometry with a left-hand spiral direction and right-hand cutting action, which reduces chatter and produces a smooth bore surface. The reamer measures 0.5312 inches in diameter with a 3.13-inch flute length and an overall length of 6.25 inches. Constructed from high speed steel with a bright uncoated finish, it delivers reliable edge retention across a range of ferrous and non-ferrous materials. Machinists and toolmakers use this reamer to bring drilled holes to final size with tight dimensional tolerance.\u003c\/p\u003e\u003cp\u003eThis hand reamer is suited for bench work and manual reaming operations where a machine spindle is not used. It is typically applied in maintenance, repair, and fabrication environments where precise hole sizing is required on assembled components or in locations that are difficult to reach with powered equipment. The straight shank design seats cleanly in a tap wrench or adjustable handle for controlled manual feed. It is appropriate for use in job shops, maintenance facilities, and general metalworking applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5312-inch reamer diameter for precise hole finishing to close tolerances\u003c\/li\u003e\n\u003cli\u003eSpiral flute design with left-hand helix reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard manual reaming operation\u003c\/li\u003e\n\u003cli\u003e8 flutes provide even chip distribution and consistent bore geometry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction offers strong wear resistance across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating thickness to account for in critical tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard hand reamer for use in tap wrenches and adjustable reamer handles that accept a straight shank.

Secure the workpiece before reaming and apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Always rotate the reamer in the cutting direction only; reversing rotation can damage the cutting edges. Follow applicable shop safety procedures when working with sharp-edged cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.5312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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: 27112837\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: 2329720\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730347852082,"sku":"2329720","price":211.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ef53b704c5d7b1fcd1c18d1193817e7.jpg?v=1788715782","url":"https:\/\/voomisupply.com\/products\/hertel-2329720-hand-reamer-0-5312-in-8-flutes-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
