Ford 79125003 Countersink 90 Degree 6 Flute Hss","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.A. FORD 79125003 is a 6-flute high-speed steel countersink designed for right-hand cutting at a 90-degree included angle. With a 1-1\/4 inch head diameter and a 1\/2 inch straight-cylindrical shank, this single-end tool mounts in standard drill presses, CNC machining centers, or hand-held power drills wherever a rigid, repeatable countersink is needed. The bright, uncoated finish preserves the base HSS hardness without added coating thickness, making it well-suited for applications where close dimensional control is required. At 3 inches overall length, it provides adequate clearance for most fixture setups. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary users.\u003c\/p\u003e\u003cp\u003eThis countersink is built for production and maintenance machining environments where a wide range of workpiece materials must be processed at a single station. It handles chamfering, countersinking, and deburring operations across alloy steel, mild steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. The 6-flute geometry distributes cutting load evenly, reducing chatter on harder materials and improving finish quality on softer ones. The tool does not include a pilot and is a head-only countersink, so workpiece positioning is operator-controlled.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree included angle, 45-degree centerline angle for standard fastener seat geometry\u003c\/li\u003e\n\u003cli\u003e6-flute design reduces chatter and improves surface finish across material types\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness for interrupted cuts and varied materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish maintains base HSS properties with no coating buildup\u003c\/li\u003e\n\u003cli\u003e1\/2 inch straight-cylindrical shank fits standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eRated for chamfering, countersinking, and deburring in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any machine tool or power drill accepting a 1\/2 inch straight-cylindrical shank, including drill presses, CNC mills, and hand-held drills.

Power down and lock out the machine spindle before inserting or removing the tool from the collet or chuck. Secure the shank to the full recommended grip depth and verify runout before cutting. Do not exceed the spindle speed range appropriate for the workpiece material and tool diameter as specified in the machine manufacturer or tooling reference data.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 45 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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip\/Nose Diameter\u003c\/strong\u003e: 0.370 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: 79125003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743869239602,"sku":"79125003","price":132.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d49699b9482625bc81a9cd0bbb36e22a.jpg?v=1788850591","url":"https:\/\/voomisupply.com\/products\/m-a-ford-79125003-countersink-90-degree-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
