It features a 100-degree included angle (50-degree centerline angle) and a bright, uncoated finish. The 1\/2-inch straight-cylindrical shank fits standard drill press and lathe tooling. With a 1-inch head diameter and a tip diameter of 0.1200 inches, this tool delivers clean, accurate countersinks in both production and maintenance environments. It is sized for general metalworking and fabrication shops where consistent hole preparation is required.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for use on a broad range of materials including alloy steel, mild steel, stainless steel, high-tensile steel, high-nickel steel, Monel, cast iron, aluminum, brass, magnesium, magnesium alloy, and plastic. The right-hand cutting direction and single-flute geometry make it straightforward to control feed rate and finish quality. Typical applications include screw-seat preparation, edge chamfering, and burr removal following drilling operations in both manual and CNC setups. It does not include a pilot and is configured as a single-end tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100-degree included angle for standard fastener seat preparation and chamfering\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design for controlled cut and reduced chatter on a variety of materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids across multiple material types\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 1\/2-inch shank for compatibility with standard toolholders and drill chucks\u003c\/li\u003e\n  \u003cli\u003eNo pilot required — works directly on pre-drilled holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style countersink for use in drill presses, lathes, and manual or CNC machining centers accepting a 1\/2-inch straight-cylindrical shank.

Secure the shank firmly in a drill chuck or toolholder before operation and confirm the workpiece is clamped or fixtured before engaging the cut. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect the cutting edge for wear or chipping before each use and replace if the edge shows damage that could affect countersink geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 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: 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 Diameter\u003c\/strong\u003e: 0.1200 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\u003eTool Application\u003c\/strong\u003e: Chamfering, Countersinking, Deburring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 61100004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51751520567602,"sku":"61100004","price":89.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/824437db4aa2a87f6a2f4e419c31f594.jpg?v=1788923707","url":"https:\/\/voomisupply.com\/products\/m-a-ford-61100004-countersink-100-degree-1-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
