It produces a 90-degree included angle chamfer with a 0.066-inch chamfer width, making it well suited for deburring and edge-breaking operations in tight or blind access conditions. The cutter head measures 3\/8 inch in diameter, the neck diameter is 0.237 inches, and the overall length is 4 inches. An AlTiN coating extends tool life in ferrous and hardened materials. Six flutes deliver smooth chip evacuation and a clean finish in a single pass.\u003c\/p\u003e\u003cp\u003eThis back chamfer tool is used in precision machining environments including aerospace, die and mold, and general metalworking shops. It is installed in CNC machining centers and manual mills wherever a back or reverse chamfer is required on a drilled or bored hole. The 3\/8-inch shank diameter is compatible with standard collet chucks and end mill holders. It handles materials such as alloy steel, tool steel, stainless steel, and cast iron where the AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree included angle produces consistent back chamfers in a single plunge\u003c\/li\u003e\n\u003cli\u003e0.066-inch chamfer width for controlled, repeatable edge breaks\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves performance in hardened and ferrous materials\u003c\/li\u003e\n\u003cli\u003e6-flute geometry supports smooth chip flow and fine surface finish\u003c\/li\u003e\n\u003cli\u003e0.237-inch neck diameter enables reach into confined bore features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual milling machines equipped with a standard 3\/8-inch collet, end mill holder, or equivalent tool holding system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by qualified machinists following standard CNC tooling setup procedures. Confirm the spindle is fully stopped and the machine is in a safe state before loading or unloading the cutter. Secure the 3\/8-inch shank firmly in a properly sized collet or end mill holder to the holder manufacturer torque recommendation. Verify runout before cutting and use appropriate speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Head Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.066 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.237 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 910470-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51743232262450,"sku":"910470-C3","price":201.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d84fc5d56956c6d048f56f8e71525ca_e9214ed2-f3ef-49c4-9b0c-d9784480c926.jpg?v=1788844289","url":"https:\/\/voomisupply.com\/products\/harvey-tool-910470-c3-back-chamfer-3-8-in-90-deg-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
