Each countersink features a 6-flute design with a 60-degree included angle, producing clean, consistent seat profiles for flat-head fasteners. Head diameters range from 1\/4 inch to 1 inch, giving machinists and fabricators a broad size selection in a single kit. Shanks are straight and sized at approximately 1\/2 inch and 1\/4 inch (12.70 mm and 6.35 mm) to fit standard drill chucks and CNC tool holders. The bright, uncoated finish is typical for general-purpose HSS tooling intended for a wide range of cutting conditions.\u003c\/p\u003e\n\u003cp\u003eThis set suits production and maintenance environments where multiple countersink diameters are needed without changing tool holders repeatedly. Common applications include preparing holes for flat-head machine screws, wood screws, and aerospace-style fasteners. The included wood block storage keeps tools organized and accessible on a workbench or in a tool crib. The set is appropriate for use in manual drill presses, lathes, and light CNC operations. Machinists, toolroom technicians, and maintenance mechanics are the primary installers and users of this type of tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-piece set covers 1\/4 inch to 1 inch head diameters in a single kit\u003c\/li\u003e\n  \u003cli\u003e6-flute geometry produces smooth, chatter-resistant countersink seats\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle suits standard flat-head fastener specifications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles steel, aluminum, wood, and plastics\u003c\/li\u003e\n  \u003cli\u003eStraight shank design fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eWood block storage keeps the set organized and prevents tool damage\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, lathes, hand drills, and light-duty CNC equipment accepting straight-shank tooling.

Always secure the workpiece firmly before beginning the cut and start at a reduced RPM to confirm seat alignment before reaching full cutting speed. Inspect the cutting edges for wear or chipping before each use, and replace any tool showing damage to avoid irregular seat profiles. Refer to machine manufacturer guidelines and applicable shop safety standards for spindle speed recommendations based on material type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Head Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Head Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.70 mm \/ 6.35 mm\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\u003eTool Material\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\u003eStorage Unit\u003c\/strong\u003e: Wood Block\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC20608S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717951226162,"sku":"SC20608S","price":166.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a81a2a0cc137877d9dee3d3e1452a132.jpg?v=1788547708","url":"https:\/\/voomisupply.com\/products\/value-collection-sc20608s-countersink-set-8-pc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
