With a 3\/8 inch cutter head diameter, a 90-degree included angle, and 0.066 inch chamfer width, this tool handles deburring and back-chamfering operations in a single pass. The 6-flute geometry supports smooth cutting action and efficient chip evacuation. An AlTiN coating extends tool life in ferrous and hardened materials. Machinists and toolroom operators use this cutter in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis back chamfer cutter suits precision machining applications in job shops, production environments, and toolrooms. It is used when a standard chamfer mill cannot reach the back edge of a drilled or bored feature. Common applications include deburring cross-holes, back-spotting, and chamfering counterbore exits in steel, stainless, cast iron, and similar materials. The 3\/8 inch shank diameter is compatible with standard ER collets and end mill holders. The 0.237 inch neck diameter provides clearance for reaching into deep features without interference.\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\u003e0.066 inch chamfer width for consistent, repeatable edge breaks\u003c\/li\u003e\n\u003cli\u003e6-flute design for smooth cutting and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for extended tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e0.237 inch neck diameter allows access to recessed and hard-to-reach features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills with standard 3\/8 inch collet chucks or end mill holders.

Power down and lock out the spindle before changing tooling. Verify runout after installation, as even minor runout can affect chamfer width consistency on a 6-flute cutter. Follow the machine tool manufacturer guidelines for speeds and feeds when working with AlTiN-coated carbide tooling.\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: 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\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 943470-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51746372354354,"sku":"943470-C3","price":195.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d84fc5d56956c6d048f56f8e71525ca_9ad811b6-eb9b-4e5a-bcec-653a7e058032.jpg?v=1788869152","url":"https:\/\/voomisupply.com\/products\/harvey-tool-943470-c3-back-chamfer-cutter-3-8-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
