With a 0.4690 inch cutting diameter and a 4 inch overall length, this reamer delivers tight tolerances and consistent surface finish in through-holes and blind holes alike. The straight-cylindrical shank provides secure, concentric holding in drill chucks and collet holders. Six straight flutes with a right-hand cutting direction remove material efficiently while maintaining dimensional accuracy. The bright, uncoated carbide construction suits a wide range of materials where coatings are not required.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for use in CNC machining centers, manual mills, and drill presses across production and job-shop environments. It is sized within the 0.4000 to 0.4999 inch diameter range and is appropriate for finishing pre-drilled or bored holes to close tolerance. Machinists, tool-and-die makers, and general machine shop technicians are the primary users. The straight flute geometry works well in materials that do not require spiral flute chip evacuation, such as cast iron, brass, and certain steels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.4690 inch cutting diameter for precise hole sizing within the 0.4000 to 0.4999 inch range\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance over high-production cycles\u003c\/li\u003e\n\u003cli\u003eSix straight flutes with right-hand cutting direction for smooth, consistent material removal\u003c\/li\u003e\n\u003cli\u003e1-3\/8 inch flute length accommodates typical through-hole and shallow blind-hole depths\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for straightforward chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill chucks, ER collet holders, and similar straight-shank toolholding systems on CNC and manual machine tools requiring a 0.4690 inch finished hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers should be installed by qualified machinists following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Secure the shank with sufficient clamping force to prevent slippage but avoid overtightening collet nuts beyond manufacturer toolholder specifications. Always pre-drill or bore the hole to the appropriate undersize before reaming, and use cutting fluid compatible with the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.4690 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: 45676913\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734158639410,"sku":"45676913","price":259.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7df2aa6d9a5e58cca44ae39e70d3059.jpg?v=1788761134","url":"https:\/\/voomisupply.com\/products\/hertel-45676913-chucking-reamer-0-4690-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
