Each countersink features 6 flutes and a 90-degree included angle, producing clean, consistent chamfers in a single pass. Shank diameters range from 1\/4 inch to 1\/2 inch, and overall lengths span 1.5 inches to 2.75 inches across the set. The bright polished finish reduces friction and aids chip evacuation. This set is appropriate for machinists, tool-and-die tradespeople, and maintenance technicians who need a range of countersink sizes on hand without pulling individual tools.\u003c\/p\u003e\n\u003cp\u003eThis set is suited for countersinking fastener seats in metal, wood, and composite materials across light manufacturing, maintenance, and fabrication environments. The 90-degree angle matches the most common flat-head machine screw and bolt standards used in general metalworking and assembly. The included plastic storage block keeps all four tools organized and protected between uses, making it practical for both shop and field service applications where multiple fastener sizes are encountered on a single job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-piece set spans 1\/4 inch to 1 inch head diameter range\u003c\/li\u003e\n  \u003cli\u003e6-flute geometry for smooth finish and reduced chatter\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle matches standard flat-head fastener specifications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright polished finish aids chip flow and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003eIncludes plastic storage block for organized tool retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink set compatible with standard drill presses, CNC machining centers, and hand-held drill drivers accepting 1\/4 inch to 1\/2 inch round shanks.

Secure the workpiece firmly before operation and confirm the drill chuck is properly tightened to the appropriate shank diameter before starting the spindle. Select spindle speed according to workpiece material and tool diameter following standard machining reference tables. Inspect each countersink for chipping or wear before use and do not exceed the tool's rated capacity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Head Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Head Diameter\u003c\/strong\u003e: 1.0 inches (1 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Shank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Shank Diameter\u003c\/strong\u003e: 0.50 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Overall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Overall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eStorage Unit Type\u003c\/strong\u003e: Block\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStorage Unit Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 79000013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51746736701746,"sku":"79000013","price":191.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/791a6599dcd5e3292232b5d9f716cb11.jpg?v=1788873237","url":"https:\/\/voomisupply.com\/products\/m-a-ford-79000013-countersink-set-4-pc-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
