The cutter head measures 0.08 inches in diameter with a 90-degree included angle and a chamfer width of 0.014 inches. With 4 flutes and a bright, uncoated finish, this tool delivers clean, consistent chamfer geometry in ferrous and non-ferrous materials. The 0.047-inch neck diameter allows it to reach into confined passages where standard chamfer tools cannot access, making it a practical choice for precision machining work.\u003c\/p\u003e\u003cp\u003eThis back chamfer cutter is used in CNC machining centers and manual milling applications where back-side edge preparation is required. Typical applications include deburring and chamfering the reverse side of cross-drilled holes, undercut features, and intersecting bores in close-tolerance components. It is well suited for aerospace, medical device, mold and die, and general precision machining environments where access is restricted and burr removal on hidden edges is critical to part function and assembly fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.08 inches cutter head diameter for work in small-diameter holes and tight-access features\u003c\/li\u003e\n\u003cli\u003e90-degree included angle produces standard chamfer geometry on back-side edges\u003c\/li\u003e\n\u003cli\u003e0.014 inches chamfer width for fine, controlled edge breaks\u003c\/li\u003e\n\u003cli\u003e4 flutes for improved chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003e0.047 inches neck diameter enables reach into restricted passages\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/8-inch collet or chuck systems on CNC machining centers, VMCs, and manual mills requiring back chamfering capability in small-diameter bores.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified machinist or CNC programmer. Secure the 1\/8-inch shank in a precision collet or end mill holder, verifying runout before cutting. Confirm spindle speed and feed rate are appropriate for the workpiece material and cutter diameter before engaging the tool. Always power down and lock out the machine before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Head Diameter\u003c\/strong\u003e: 0.08 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.014 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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.047 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\/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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 943380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51729295573298,"sku":"943380","price":123.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b03ebc3521ea169da0c0b66dee53cb2c.jpg?v=1788702558","url":"https:\/\/voomisupply.com\/products\/harvey-tool-943380-back-chamfer-cutter-0-08in-90-deg-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
