It features a 120-degree included angle and a 1-1\/2-inch head diameter, making it well suited for chamfering, countersinking, and deburring operations across a wide range of workpiece materials. The straight-cylindrical shank measures 3\/4 inches in diameter, and the tool runs 3-1\/2 inches in overall length. A tip nose diameter of 0.430 inches ensures clean entry. Right-hand cutting direction and HSS construction make this a durable, general-purpose countersink for machine shop and fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThis countersink is designed for use on manual mills, CNC machining centers, drill presses, and similar rotary equipment. Its material compatibility spans a broad spectrum: alloy steel, mild steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. It does not include a pilot and is sold as a head-and-shank assembly, not a head-only unit. Machinists and tool-and-die professionals use this type of countersink for production chamfering and screw-seat preparation in both one-off and repeat-run applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-degree included angle (60-degree centerline angle) for standard chamfer profiles\u003c\/li\u003e\n  \u003cli\u003e6 flutes for smoother cutting action and improved chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use across the full listed material range\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch straight-cylindrical shank for common collet and chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eNo pilot required, allowing flexible positioning on the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use on alloy steel, mild steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic workpieces in standard machining setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists or tool operators into a compatible 3\/4-inch collet, end mill holder, or drill chuck. Ensure the machine spindle is fully stopped and locked out before mounting or removing the countersink. Set spindle speed according to the workpiece material and tool diameter using standard HSS speed-and-feed references. Avoid excessive feed pressure, which can cause chatter or premature edge wear on harder materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Nose Diameter\u003c\/strong\u003e: 0.430 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 79150006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51739311997234,"sku":"79150006","price":186.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56e3ca94deb8803a847b35835b9ed238.jpg?v=1788812980","url":"https:\/\/voomisupply.com\/products\/m-a-ford-79150006-countersink-120-degree-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
