Built with a 100-degree included angle and six flutes, it delivers clean, consistent results across a wide range of materials. The straight-cylindrical shank measures 0.5 inches in diameter with an overall length of 2.75 inches. The bright uncoated finish is suited for general-purpose machining where coating compatibility with specific cutting fluids is a consideration. Machinists and tool-and-die professionals working in production or maintenance settings will find this tool well matched to high-volume countersinking operations.\u003c\/p\u003e\u003cp\u003eThis countersink is intended for use on metal and non-metal workpieces in machining, fabrication, and assembly operations. Its six-flute configuration reduces chatter and improves surface finish compared to fewer-flute designs. It is appropriate for use in CNC machining centers, manual mills, and drill press setups where repeatable countersink geometry is required. No pilot is included, making it suited for applications where a pilot is unnecessary or where the operator provides piloting through fixturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100-degree included angle for standard aerospace and fastener-seating countersink profiles\u003c\/li\u003e\n\u003cli\u003eSix flutes for reduced chatter and improved finish quality\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a broad range of cutting fluids and lubricants\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for compatibility with standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eSingle-end design with no pilot — suitable for fixturing-guided or free-hand countersinking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for chamfering, countersinking, and deburring operations on alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this countersink should be performed by qualified machinists familiar with rotary cutting tools. Secure the 0.5-inch shank fully within the collet or chuck before operation and verify runout within acceptable tolerance for the application. Always bring the spindle to a full stop before measuring or inspecting the countersink. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 50 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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip\/Nose Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody 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\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\u003eTool Application\u003c\/strong\u003e: Chamfering, Countersinking, Deburring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.43 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 78100004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51732508901682,"sku":"78100004","price":277.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1e4c44f78f5037f16e7bfbba6201ed6.jpg?v=1788743771","url":"https:\/\/voomisupply.com\/products\/m-a-ford-78100004-countersink-100-deg-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
