The set covers a head diameter range of 3\/16 inches to 1-1\/4 inches, with all tools ground to a 90-degree included angle and a 45-degree centerline angle. Each countersink features a 6-flute, right-hand cutting geometry with a straight shank, providing smooth chip evacuation and clean seat finishes. The bright, uncoated finish is standard for cobalt steel tooling and holds up under the elevated heat of hard-material work. Tools are stored in a fitted wood block for organization and bench-top access.\u003c\/p\u003e\n\u003cp\u003eThis set is suited for machine shops, maintenance facilities, and fabrication environments where a range of countersink sizes is needed at one station. It handles deburring, chamfering, and seat preparation for flat-head fasteners across a wide diameter range. The straight shank is compatible with standard drill chucks and quick-change tool holders. Both manual drill press setups and CNC applications can use these tools. The wood block storage keeps sizes organized and prevents edge damage between uses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-piece set covering 3\/16 inches to 1-1\/4 inches head diameter range\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction for elevated heat and hardness resistance\u003c\/li\u003e\n  \u003cli\u003e6-flute geometry with right-hand cutting direction for smooth, chatter-free seats\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle suits standard flat-head fastener countersink geometry\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard drill chucks and quick-change holders\u003c\/li\u003e\n  \u003cli\u003eFitted wood block storage protects cutting edges and keeps set organized\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink set for use with straight-shank drill chucks and tool holders across drill press, hand drill, and CNC applications requiring a 90-degree countersink angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCountersinks should be installed by machinists or skilled tradespeople familiar with drilling and deburring operations. Secure the workpiece before operation and set spindle speed appropriate to the material being cut — lower speeds for harder materials. Inspect the shank and cutting edges before each use and remove any tools showing chipping or excessive wear. Store tools in the provided wood block to protect flute geometry between uses.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Head Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Head 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 Type\u003c\/strong\u003e: Straight\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: Cobalt 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 Type\u003c\/strong\u003e: Wood Block\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.35 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: SC21901210S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51724028739890,"sku":"SC21901210S","price":613.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/348564f4f607f85446d1eaf770b24d5f_ebd35385-cc2d-4aca-900e-803adbc21e88.jpg?v=1788611861","url":"https:\/\/voomisupply.com\/products\/value-collection-sc21901210s-countersink-set-10-pc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
