With a 100-degree included angle and a 3\/16-inch shank diameter, it handles chamfering, countersinking, and deburring across a wide range of materials. The straight-cylindrical shank fits standard drill chucks and collet holders without modification. The bright, uncoated finish is suitable for general-purpose shop use. At 1.5 inches overall length, it is compact enough for use in tight access areas. This tool is used by machinists, tool-and-die professionals, and general fabricators working on precision hole finishing.\u003c\/p\u003e\u003cp\u003eThis countersink is built for production and maintenance environments where consistent chamfer quality is required. The 6-flute geometry reduces chatter and produces a cleaner finish compared to single- or three-flute designs. It is rated for use on alloy steel, mild steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, high-nickel steel, high-tensile steel, Monel, and plastic. The 0.040-inch tip diameter allows the tool to start on a pre-drilled hole without a pilot. No pilot is included or required for standard countersinking operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100-degree included angle for standard countersink and chamfer geometry\u003c\/li\u003e\n\u003cli\u003e6-flute design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction supports use across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for general-purpose dry or lubricated cutting\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eNo pilot required  -  0.040-inch tip diameter self-starts on pre-drilled holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose countersink compatible with standard drill presses, CNC machining centers, and hand-held drilling equipment accepting a 3\/16-inch straight-cylindrical shank.

Secure the workpiece firmly before starting the cut. Apply cutting fluid when working on ferrous or stainless materials to extend tool life and improve finish quality. Inspect the cutting edges for wear or chipping before each use and replace the tool if edges are degraded to avoid poor chamfer geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.040 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\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: 79018704\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51742117232946,"sku":"79018704","price":26.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89aed5ff7aab9a24849b408b3000dacc.jpg?v=1788835370","url":"https:\/\/voomisupply.com\/products\/m-a-ford-79018704-countersink-100-degree-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
