It operates at a 90-degree included angle and produces a 0.044 inch chamfer width. The cutter head diameter is 1\/4 inch, with a 5-flute geometry that improves chip evacuation and surface finish in ferrous and non-ferrous materials. The bright uncoated finish makes it suitable for a wide range of base materials. Machinists and toolroom technicians use this tool in CNC machining centers and manual mills where back-side deburring or chamfering is required.\u003c\/p\u003e\u003cp\u003eThis back chamfer cutter is suited for applications where a standard front-entry chamfer tool cannot reach, such as counterbored holes, undercuts, and reverse-side edge breaks. It is commonly used in precision machining environments including aerospace, medical device, and general metalworking shops. The reduced neck diameter allows the cutter to reach into recessed features without interference from the shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree included angle for standard back chamfer geometry\u003c\/li\u003e\n\u003cli\u003e0.044 inch chamfer width for controlled, consistent edge breaks\u003c\/li\u003e\n\u003cli\u003e5-flute design promotes smoother cuts and improved chip clearance\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eReduced neck diameter of 0.156 inches allows access to recessed and counterbored features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch collets and tool holders on CNC machining centers and manual milling machines where back chamfering or reverse-side deburring is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by a machinist or toolroom technician into a compatible 1\/4 inch collet or end mill holder. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Verify runout with a dial indicator after installation to maximize tool life and chamfer consistency. Do not use this cutter as a drilling tool or apply axial plunge loads not intended for this geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Head Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.044 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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.156 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: 0.06 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: 938216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51738673971506,"sku":"938216","price":156.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b03ebc3521ea169da0c0b66dee53cb2c_75509281-dd9b-432a-ac85-31eff04e37a3.jpg?v=1788802641","url":"https:\/\/voomisupply.com\/products\/harvey-tool-938216-back-chamfer-1-4-in-90-deg-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
