Ground to a wire gauge No. 43 diameter of 0.0890 inches, it holds a tight tolerance of 0.0000 to 0.0002 inches, making it suitable for close-tolerance bore work where accuracy is critical. The 4-flute straight geometry and bright uncoated finish are standard for this type of carbide reamer, which is typically run in CNC machining centers, drill presses, and manual lathes equipped with collet or drill chucks. Machinists and toolroom technicians are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis reamer is used in production and toolroom environments where small-diameter, tight-tolerance holes are required in ferrous and non-ferrous materials. With an overall length of 2 inches and a flute length of 0.5 inches, it is suited for shallow through-holes and short blind bores. The straight cylindrical shank allows direct clamping in standard collets and drill chucks. Applications include instrument manufacturing, aerospace component machining, and general precision metalwork where wire-gauge hole sizes are specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 43 diameter: 0.0890 inches with tolerance of 0.0000 to 0.0002 inches\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in precision reaming\u003c\/li\u003e\n\u003cli\u003e4-flute straight design for consistent chip evacuation in short-flute applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids in a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for secure clamping in collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, standard for conventional reaming operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard wire-gauge chucking reamer for use in CNC machining centers, drill presses, and lathes equipped with collet chucks or drill chucks that accept a straight cylindrical shank at this diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist or toolroom technician familiar with reaming practices. Ensure the spindle and workpiece are properly secured and that the machine is at a complete stop before mounting or removing the tool from its holder. Apply an appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain dimensional accuracy. Do not use this reamer to remove excessive stock; pre-drill or bore the hole to within the recommended reaming allowance before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Gauge)\u003c\/strong\u003e: No. 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 79890786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734441460018,"sku":"79890786","price":67.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffaeeaefd5bec0febb83351b0cf7ee19.jpg?v=1788763066","url":"https:\/\/voomisupply.com\/products\/hertel-79890786-chucking-reamer-wire-43-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
