Built from solid carbide, this single-end tool delivers consistent cutting performance on ferrous and non-ferrous materials. It features a 90-degree chamfer angle, a 0.36-inch cutting diameter, a 0.055-inch chamfer depth, and a bright finish that allows easy wear inspection during use. The 3\/8-inch shank diameter provides rigid tool holding in standard collet chucks and end mill holders. Machinists and tooling professionals rely on this style of back chamfer tool for deburring and edge-breaking operations that standard chamfer mills cannot reach.\u003c\/p\u003e\u003cp\u003eThis back chamfer tool is suited for CNC machining centers and manual mills where back-side edge preparation is required. Typical applications include aerospace, automotive, and general metalworking operations where cross-drilled holes, intersecting bores, or countersunk features need a clean, consistent chamfer on the underside. The 1\/32-inch flat width and 1\/4-inch neck diameter allow the tool to pass through tight bore clearances before engaging the back edge. The 2-1\/2-inch overall length provides reach for moderate-depth applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for wear resistance and rigidity\u003c\/li\u003e\n\u003cli\u003e90-degree chamfer angle for standard back-edge preparation\u003c\/li\u003e\n\u003cli\u003e0.36-inch cutting diameter with 0.055-inch chamfer depth\u003c\/li\u003e\n\u003cli\u003e1\/32-inch flat width allows passage through tight bore clearances\u003c\/li\u003e\n\u003cli\u003eBright finish for easy wear monitoring\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter fits standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use back chamfer tool compatible with CNC machining centers and manual mills equipped with standard 3\/8-inch collet chucks or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with rotary cutting tool safety. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Confirm the shank is fully seated and the collet or set screw is properly torqued per the tool holder manufacturer specifications before running. Back chamfer tools require a pre-drilled or bored through-hole large enough to pass the neck diameter before engaging the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Depth\u003c\/strong\u003e: 0.055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat Width\u003c\/strong\u003e: 1\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02703049\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728093937970,"sku":"02703049","price":103.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbef4911f6c3f9d8d178f46a4b6bff34.jpg?v=1788687828","url":"https:\/\/voomisupply.com\/products\/accupro-02703049-solid-carbide-back-chamfer-0-36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
