With a 0.1240 inch diameter and a right-hand cutting direction, this reamer delivers accurate, smooth bore finishing in drilled holes. It features 4 straight flutes with a bright, uncoated finish and is classified as an under-size reamer, making it suitable for applications that require tight dimensional tolerances. The straight-cylindrical shank allows for reliable grip in standard chucks and collets. Overall length is 2.75 inches with a 0.875 inch flute length. Machinists and tool-and-die professionals use this reamer for precision finishing work on small-diameter holes.\u003c\/p\u003e\u003cp\u003eThis reamer is well suited for light-duty precision reaming operations in machine shops, tool rooms, and production environments. Its compact size and under-size designation make it a practical choice for finishing bores where close dimensional control is required. The straight flute geometry works effectively on a range of ferrous and non-ferrous materials. It is compatible with standard drill presses, lathes, CNC machining centers, and manual milling machines equipped with an appropriate chuck or collet setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1240 inch diameter with under-size designation for tight-tolerance bore finishing\u003c\/li\u003e\n\u003cli\u003e4 straight flutes with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eHSS tool material for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for secure seating in standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 2.75 inches with 0.875 inch flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with a compatible chuck or collet accepting a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this reamer should be performed by qualified machinists or tooling technicians. Always secure the shank fully in a properly sized chuck or collet before operation, and verify spindle runout is within acceptable limits to avoid reamer damage or out-of-tolerance results. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never force a reamer through a hole smaller than the recommended pre-drilled diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.1240 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size\u003c\/strong\u003e: Under Size (0.1240 U\/S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 72293061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754342875442,"sku":"72293061","price":33.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c51c095728745ff1dc969ca3208c4fa6_cecfda7a-8f8d-4fb8-a463-3f942958cca8.jpg?v=1788944498","url":"https:\/\/voomisupply.com\/products\/hertel-72293061-chucking-reamer-0-1240-in-hss-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
