It features a 100-degree included angle (50-degree centerline angle) and a 3\/8-inch head diameter, making it well suited for standard fastener seat preparation. The straight cylindrical 1\/4-inch shank fits common drill chucks and quick-change holders. At 2 inches overall length, it is compact enough for close-quarters work. The bright uncoated finish is appropriate for general-purpose cutting without specialty coating requirements. Machinists, tool-and-die workers, and maintenance technicians are the typical end users.\u003c\/p\u003e\u003cp\u003eThis countersink is used in job shops, production machining cells, and maintenance-repair-overhaul environments where precise fastener seat geometry is required. Its single-flute design reduces chatter and produces a clean, smooth finish on the countersink seat. The broad material compatibility makes it a practical choice when operators work across mixed-material workpieces in a single setup. It is sold individually as a single-piece unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100-degree included angle for standard fastener countersinking applications\u003c\/li\u003e\n\u003cli\u003eSingle flute design minimizes chatter and improves surface finish quality\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a wide material range\u003c\/li\u003e\n\u003cli\u003e1\/4-inch straight cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose use across multiple materials\u003c\/li\u003e\n\u003cli\u003eNo pilot required — single-end design for direct plunge countersinking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces.

Secure the shank fully in the drill chuck or collet and verify concentricity before engaging the workpiece. Always power down and lock out the machine spindle before changing or inspecting the tool. Use appropriate cutting fluid or lubricant when working with ferrous materials to extend tool life and improve finish quality.\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: 1\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\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip\/Nose Diameter\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\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: 61037504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51734085632306,"sku":"61037504","price":29.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/924475a68b3d5ebed562b5421b149849.jpg?v=1788760834","url":"https:\/\/voomisupply.com\/products\/m-a-ford-61037504-countersink-100-degree-1-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
