It features a 100-degree included angle (50-degree centerline angle) and a 3\/4-inch head diameter paired with a 1\/2-inch straight cylindrical shank. The bright, uncoated finish suits general-purpose shop use where coating is not required. Overall length is 2.75 inches. Machinists, tool-and-die technicians, and CNC setup operators install this tool in standard drill presses, mills, or hand-held drilling equipment when a clean, consistent countersink seat is required.\u003c\/p\u003e\u003cp\u003eThis countersink is suited for production and job-shop environments where a single tool must handle multiple material types. The 100-degree angle is commonly specified for fastener seating in aerospace-adjacent and general metalworking applications. Compatible workpiece materials include alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel. It does not include a pilot and is not a head-only style, making it ready to run straight from the package without additional components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100-degree included angle for standard fastener countersink profiles\u003c\/li\u003e\n\u003cli\u003e6 flutes for smoother cutting action and reduced chatter on harder materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a broad material range\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish for general-purpose metalworking use\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical 1\/2-inch shank fits standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eNo pilot required  -  single-end design installs without additional accessories\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, vertical mills, and hand-held drilling equipment accepting a 1\/2-inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the countersink from the collet or chuck. Secure the shank to the full recommended grip depth and verify runout before cutting. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/4 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\/2 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: 0.2100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\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: 79075004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743919702322,"sku":"79075004","price":65.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c1fbc943b32dc44e225a172b308a60f.jpg?v=1788851297","url":"https:\/\/voomisupply.com\/products\/m-a-ford-79075004-countersink-100-deg-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
