It features a 100-degree included angle (50-degree centerline angle), a 3\/8-inch head diameter, and a straight-cylindrical 1\/4-inch shank. The bright, uncoated finish suits general-purpose cutting across a wide range of workpiece materials. At 2 inches overall length, it fits standard drill presses, CNC machines, and hand-held power tools. Machinists and tool-and-die technicians are the primary users of this type of tooling.\u003c\/p\u003e\u003cp\u003eThis countersink is suited for production and maintenance applications in machine shops, fabrication facilities, and industrial maintenance environments. It is compatible with a broad range of materials including alloy steel, mild steel, stainless steel, high-tensile steel, high-nickel steel, cast iron, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. The 6-flute geometry provides a smooth cutting action and reduces chatter compared to single- or double-flute designs, making it appropriate for finish-quality chamfer work on drilled holes.\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 quality\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 general-purpose cutting applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/4-inch shank fits standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eNo pilot required  -  single-end, pilotless design for flexible positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with materials including alloy steel, mild steel, stainless steel, high-tensile steel, high-nickel steel, cast iron, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic.

Secure the shank firmly in the chuck or collet before operation and confirm the spindle is at a full stop before tool changes. Set spindle speed appropriate to the workpiece material and tool diameter per standard machining feeds-and-speeds tables. Do not force the tool into the cut; allow the flutes to clear chips freely to prevent tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/8 inches\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: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip\/Nose Diameter\u003c\/strong\u003e: 0.0900 inches\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\u003eTool Application\u003c\/strong\u003e: Chamfering, Countersinking, Deburring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Brass, Cast Iron, High-Nickel Steel, High-Tensile Steel, Magnesium, Magnesium Alloy, Mild Steel, Monel, Plastic, Stainless Steel\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: 79037504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743951257906,"sku":"79037504","price":30.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd47480de9d05bc07b19863dd9dc75dc.jpg?v=1788851829","url":"https:\/\/voomisupply.com\/products\/m-a-ford-79037504-countersink-100-deg-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
